Title: R6 rear shock on the FZS600
Post by: kebab19 on 05 June 2013, 05:09:47 PM
Credit to Luke / DevilsYam for original inspiration
Credit to DCurzon for his top-hat spacer idea

These shocks fit but with a bit of hassle.

The standard spring is too soft unless you're a featherweight 8 stone or less & don't think about a pillion! A re-spring is needed to be safe


Although some people have transplanted the Fazer FZS 1000's rear shock onto their 600 (and this is a step in the right direction), these R6 shocks are an improvement again as they have separate high & low speed compression adjusters (particularly useful for overcoming those jarring, sharp-edged bumps that litter our public roads)

Save yourself a lot of p1ssing around by REMOVING the suspension linkages to allow the shock to fit more easily! While they're out, give 'em a good greasing.

The model you're after (13S) is the same one that all the 1000 owners are after, as well as GS500 twin owners(!) (2008 onwards shocks, it must have the compression adjusters together, not separate).  That means you'll have to watch ebay like a hawk or just buy one off a 1000 owner. Still, much cheaper than the likes of Nitron's basic emulsion shock & actually offers more adjustment options.
At 293mm long from eye centre to centre, its nearly 10mm shorter than the standard shock, so need different dogbones. I went with multiple height plates listed frequently on ebay that allow four different options & chose the highest ride height (normally +40mm) which is still slightly lower than standard.

Luke / Devilyam's suggested settings,

"Setting the high/low compression damping at 4 clicks out from full hard on the high speed adjusting nut, and 16 clicks out from full hard on the low speed compression blue screw worked well for me, and my weight. Rebound damping i have set at 16 clicks out from full hard, and that worked well, also."

Nice one kebab!


I wondered what you were up to from your comment on my previous suspension post.


You could now class yourself as fazer pioneer i reckon.


Would be interesting to hear how it feels,personally im still learning so the less hassle with fitting stuff the better but for the seasoned fazer fettlers this cold be a real good option at less cost.

Ah yes, was hinting @ what was to come  ;)
Thanks, I've made a few suspension mods in my time here (first for a 600, then for my 1000 & now back to a 600 again):

http://foc-u.co.uk/index.php/topic,7962.0.html (http://foc-u.co.uk/index.php/topic,7962.0.html)

Having said that, this wasn't my idea, Luke / Devilyam came up with the great idea for fitting these shocks to the FZS1000 & they work well. Tho I am the first to have fitted one (so far).
Haven't ventured too far on the new shock yet (6 miles, all town riding) but it feels more compliant, a little softer than the original shock but perhaps it was harsh previously because the damping had gone. I'm not sure whether to aim for settings while @ standard rear ride height or jack it up a little, but at least my kidneys will survive bumps from now on. More fine tuning to come.

I'm turning my attention to the FZS600's front-end again next. Thundercat forks have been done, TRX850 forks are another option, or R6 5SL front forks if the front speedo drive can be bored out successfully (well I do have a set of 'em sitting in the garage  :lol ). Or I may just modify the damping internals of the standard forks. Decisions decisions...

Post by: kebab19 on 10 July 2013, 09:36:07 AM
Ok I tested her quite a bit.

The shock performs superbly BUT the standard spring is on the soft side. This is unsurprising since the donor bike is considerably lighter.
I am just over 11 stone, maybe 13 in full gear and even with the spring preload wound to maximum my rear sag with me on the bike was about 52mm. Considering there is 119mm of suspension travel this is too soft (should be between a quarter to a third of travel, 30-40mm maximum). While fine for me keeping things under a ton, things might get interesting above that speed, or if you are 16 stone, or if you were to take a pillion  :eek So if you aren't heavy & ride solo, the straight shock swap is fine. I'm a bit of a suspension perfectionist, & sadly the Fazer 600's spring was too long to fit onto the R6 shock, so I ordered & fitted a heavier Faulkner's spring (£27) to get my sag closer to optimum.

Slightly disappointing as the spring change complicates things & adds more expense, but I felt it was worth mentioning to anyone considering the swap over.

Hum intresting would have tried preload up one click to 5 to stiffen spring
Wot is the bone centre to centre to maintain stock ride height?
Good work not have a 600 to play with couldn't explore this so weldone

Sag is sag,
Although adjusting preload can help temporarily if you don't have the right sag for your weight then the bike will never ever handle correctly.
This is why sag is always the first thing to be set before playing with any other adjustments!

Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 13 July 2013, 08:23:04 PM
It was your idea, Luke - all credit to you.
I maxed the preload out & that sag measurement was the best I could get. Not sure re correct dogbone length - I bought the four-way 'projection' adapter plates as one of them raises the standard rear height 40mm. I have it on this setting & it's still 3 or 4 mm shorter than standard setup, & makes the centre-stand more of a PITA to lift onto. next time it's off I'll measure the gap between holes.

When road testing it didn't feel like it completely bottomed out on me which was surprising as Irish 'B' roads are known to resemble the surface of the moon. But I'd be concerned that someone with a passenger or two-up with luggage could find it dangerous, so it can't be recommended without first uprating the spring weight. An uprated 650 lbs/inch shouild do the job, or possibly 700lbs/inch if you're ... big boned.

Andy, the FZS1000 shock will be an improvement over the standard unit, but as Luke will probably agree, its the separate high and low-speed compression damping circuits that elevates these R6 shocks into something pretty special, more in line with the ride sensation top aftermarket shock manufacturers like Nitron offer.

I've had a thou shock on my 600 "with 600 spring" for two seasons now. I never have cause to think about what the suspension is doing . A good sign that all is well in my books

The fzs 600 spring is 823 lbs/inch, so the r6 spring is way off!!
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 14 July 2013, 12:13:48 PM
Luke,
According to this thread:  http://foc-u.co.uk/index.php/topic,2078.25.html (http://foc-u.co.uk/index.php/topic,2078.25.html)
the FZS swingarm pivot to wheel spindle is about 540mm

With the standard R6 standard shock spring with preload maxed my rear sag was 52mm
With a Faulkner's 600 lb/inch spring fitted & preload maxed my sag was 40mm - getting much closer
I've just ordered a Faulkners 650lb/ inch spring, which should hopefully be perfect for me

The R6 spring length is also a PITA at 6.5 inches long; the FZS600 spring is 7 inches, so it wouldn't fit without a major amount of preload being exerted. The Faulkner springs are only 6 inches long, hence I had to have a metal spacer fitted to the bottom of the shock to take up the slack
Title: Re: R6 rear shock on the FZS600
Post by: bwizz on 14 July 2013, 05:03:26 PM
When comparing spring rates it is easy to overlook the contribution of the gas in the thou, and r6 units. a  fazer 600 unit does not have gas assistance . chap at revvs reconed the gas added 70% .
Title: Re: R6 rear shock on the FZS600
Post by: wezdavo on 14 July 2013, 06:34:25 PM
According to the fzs1000 manual its shock has a gas pressure of 1,200 kPa (12 kg/cm2, 170.7 psi)
 
But wait for this...
 
According to the fzs 600 manual its shock also has a gas pressure of 1,200 kPa (12 kg/cm2, 170.7 psi)
 
This info is obtained from the Yamaha workshop manuals spec section, where it has spring rate and such things...
 
So maybe the guy at revs was wrong?
 
Title: Re: R6 rear shock on the FZS600
Post by: bwizz on 14 July 2013, 07:55:08 PM
Bit over my head this ,but the point is the 1000 and r6 gas assistance can be adjusted
wheras the 600 oil/spring unit is fixed so in theory either should be better than the 600 basic unit, In my experience the r6 unit on my thou and the 1000 unit (600 spring) on the 600 are much better than stock
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 17 July 2013, 08:34:12 PM
Ok, I've now fitted a 650lb/inch Faulkner's spring to the shock. With the preload ring moved to maximum, sag with me on the bike is 31mm  :)
Although subjective, common consent for rear sag for roadbikes is between 30-35mm, so it looks like this is the spring weight needed to avoid bottoming out.
I'd estimate if you're over 17 stone, or regularly carry a passenger at speed, you may need to fit a heavier spring, such as 700lb/inch to the shock instead.

Some testing tomorrow, a proper workout weather permitting  :lol
Title: Re: R6 rear shock on the FZS600
Post by: wezdavo on 17 July 2013, 10:02:21 PM
Very good Kebab ;)
 
Could I trouble you for the spring size, id and length?
 
 
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 18 July 2013, 11:43:17 AM
Sure, I ordered from here:     http://www.demon-tweeks.co.uk/motorcycle/rear-springs (http://www.demon-tweeks.co.uk/motorcycle/rear-springs)

The spring I went for:
Free length - 6.0 inch / 152.4mm
Internal Diameter - 2.25 inches / 58.5mm
Rate - 650lbs ins / 114N/mm

Bear in mind that this spring is half an inch shorter than the original Yam spring; I had an alloy spacer made up to take up the gap. You might be able to fit the 7 inch version of the spring instead, but there may be too much preload by the time its compressed onto the shock. I have a contact who's a dab hand at machining parts & can knock up an identical spacer for about £20 if you need one.

A decent 20 mile spin this morning and all is (very) well now. Much firmer rear end, with 31mm probably at the sporty end of the adjustment range. I'll back the preload ramp off a couple of positions for slightly more comfort, but finally the quest for rear-end perfection is coming to an end .... matching the front-end perfection of Debrix emulators with VFR750 fork springs  :D

Post by: Fuzzy on 01 August 2013, 05:45:53 PM
Great stuff kebab, good you're getting close to your perfect setup... I can only wish I was too.

An often overlooked subject is the ease of preload adjustment. Makes a big difference to me as I ride with luggage/pillion/solo in equal amounts. The standard shock is quick and easy to adjust but I want a good adjustable shock! Answer would be a Nitron or something decent with a remote preload adjuster. Without one those aftermarket shocks are a pain as they have a threaded adjuster not notched like the oem shocks, which I found out to my expense with a Wilbers.

So before I start starving myself so I can afford a £600 shock or consider another bike, how easy is it to adjust on the R6 shock? As easy as on the standard shock?
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 01 August 2013, 07:41:34 PM
Hello,
Yes, adjustment is via a preload ramp / collar, the same as the standard shock. There is the compression reservoir at the back of the shock but it doesnt get in the way of adjusting the preload ring. For speed I remove the top bolt of the footrest hanger, letting it hang down. This allows me to pull on the spanner without gouging my fingers against it. Also, I've been using the FZS600 C-spanner to make all the adjustments.

Shock has been great so far & am now getting shorter bespoke dogbones made up in order to raise the rear another 10mm or so

Post by: kebab19 on 08 August 2013, 03:28:39 PM
Short update.
As the 'projection' dogbones still hadn't returned the rear to standard height, I had a pair of bespoke ones fabricated, 127mm from hole centre to centre.
Handling has got better with the slightly raised rear & bump energy transmission is even less than before.
They are 8mm thick & have no taper in order to give extra rigidity. Bit more blingy too, but that unfortunately highlights how grotty the rest of the bike is  :o   I've attached a pic of the rear wheel when the bike is placed on the centre-stand - does this look closer to the ground than standard?
Yes, I have a Thunderace rear caliper fitted  :)
 I have attached other pics of the custom dogbones compared to standard / 'Projection' plates.

Project R6 rear shock now complete.  :D

My modified R6 shock and dogbones from Kebab19 arrived earlier this week and I got round to fitting it yesterday. The shock and bones fitted easily and I greased all the linkage bearings whilst I was there. I went with a heavier spring than him, 700lb/ins, and dogbones that are 1mm longer at 128mm which brought the ride height to about standard, in fact probably marginally taller. I only weigh about 75kg with gear but take a pillion and hard luggage on a regular basis which is why I opted for the heavier spring.
 
Must say a big thank you to Kebab, his help and advice was invaluable and the work done is top notch. I'm looking forward to doing his debrix emulator fork mod next as the improved rear shows up the front end making it seem even harsher than before!
 
Need to set sag, test ride some more and make more adjustments but couldn't be happier with the swap so far  :D

I fitted a R6 shock at the weekend and the past few days I have been putting it through its paces..
 
I went for a Faulkner 725lb spring and 127.5 mm dog bones..
 
I am 95kg geared up and to get a rider sag of 32mm I am on preload position 7.
 
Rebound is set @ 13 clicks out, low speed  @ 13clicks out and high speed @ 2.5 turns out..
 
The bike feels fantastic, very planted.
 
The dampening control is amazing!
 
A big thank you to Kebab and Fuzzy for all there help

Dogbones look good, does it get in the way of adjusting the rebound?

Glad it worked out for you too  :)

Thought I'd also share my specs and current settings:


Still needs more saddle time to test these settings but in any case it's way better than the stock shock.

  • 128mm dogbones
  • Rider sag 33mm on notch 5 @ 75kgs geared up
  • High speed comp: 3 turns out
  • Low speed comp: 16 clicks out
  • Rebound: 15 clicks out

Hello bud, dog bones worked out well, they don't effect rebound screw at all..

Well done, Wez, you now have the same front & rear end setups as me...as will Fuzzy (shortly).

The R6 shock is indeed quite a piece of kit for a standard manufacturer's part: I really can't imagine the full spec Ohlins shock when fitted being significantly better. When you consider that Hagon's basic unit is nearly twice the price, it's actually a bit of a bargain - about £100 for conversion on top of the shock's price.

Sounds like the correct shock to me. Because the shock is shorter you must use shorter dogbones to maintain ride height (as per earlier posts in the thread with more details). As for the top mount, I think most of the thou guys who've done this mod (of which there are many) have had it drilled it out and I am not aware of any failures to date so it should be fine, as long as it's drilled straight and done properly.

getting there...
Shock - sitting in my garage.
Spring Spacer - on my desk.
Dog Bones - on my desk.
Spring - 725lb's ordered and waiting on it.
Whats left?  Drill the upper mount and get some 5mm spacers - nope! 
I'm attacking in a slightly different direction.  I'm going to sleeve down the M12 holes to match the shocks M10 fitting.  Advantage - I could refit the OE shock and still have a good, undrilled R6 shock.  Oh, and this should be easier than trying to fiddle about with spacers.  So the M12 bolt will be going and an M10 bolt fitted in its place.

Nice one, I like that idea. Let us know how you get on and your initial impression of the new shock (and perhaps what settings you have if you have time) once you have it on, I would be interested.

Have you made any improvements for the front end yet?


Title: Re: R6 rear shock on the FZS600
Post by: dcurzon on 21 January 2014, 03:49:51 PM
nope. its my daily city commuter so when i do things, i have to plan in such a way that it'll be off the road for as little time as possible.  The shock is going in for its 50,000 mile birthday.  I always have a 52l box on the back with weight in, so i'm not expecting to transform the handling into an R6, just improve it a bit.  When the shock goes in, i'll be removing the swingarm and linkages for a deep clean and grease up.  i was thinking of getting some powder coating done, but to be honest its pointless, so a good scrub will be the better and cheaper option.
The R6 shock that i have barely has any mileage on it at all - the bike was briefly ridden before being race prepped.
 
Front end needs a good strip down at some point, i'll probably go as far as painting the lowers and putting 15wt oil in (i had sponsorsip from Silkolene and then Castrol, pretty sure i have a selection of unused fork oils laying about somewhere), doubt i'll do anything too dramatic though.  Think i read on here about some cheap emulators, i'll look more into that after the shock's done, which i doubt i'll get finished until late february.

Yes, I use my bike in the same way so I know it can be awkward to find a good time to get major work done - especially if you have to work outside and need decent weather!

I have a Wingrack (heavy thing) & 52L topbox like you and it's an improvement believe me. Taken panniers and pillion ontop of that and it was still miles better than before so you won't regret it. Not too awkward to adjust the preload either.

If you can find the time to do the cartridge emu mod, do it! It's fantastic and the fact that it's so cheap to do is a bonus. Best results are with springs matched to your weight though.

Ontop of the above, I've dropped the yokes by 3mm and it's perfect for me, don't think I can do much to improve the bike now (apart from cleaning off all the winter crap)

Made in steel, should do the trick quite nicely... Anyone know what length the upper mount bolt is?  I'm guessing 65mm, so i just need to pick up an M10x65 and i'm ready to go...
oh, not quite... spring should be with me on monday, would a set of these do the trick, or am i likely to lose an eye/rib/hand?

Nice spacers  ;)

I think those spring compressors are for cars (?) and a few people (such as some coil spring compressor vendors on ebay) have claimed they are too big & therefore of limited use.

e.g. Ebay item # 201019989805 "If you have ever tried to use car spring compressors on a bike spring you will know how easy it is to do irrepareable damage to the shock unit with oversize compressors"

My own compressors are the same design as that fella & they worked well in conjunction with a half-decent vice & a 2 foot breaker bar to turn them

Done. Whilst the missus was at the park with the kid. Took the swingarm off for a good clean and grease up whilst I was at it.

I was nearly stumped as I needed an m10 x 75 bolt for the upper fixing, but found an m10 x 80 in wickes which fitted. I'll probably hunt down a high tensile bolt for that at some point.

Top hat spacers (cad design further up this page) did the job nicely.  They had been turned slightly out of spec so had to take about quarter mm off each side to get the shock in. Can't grumble as they were knocked up for a pint!

Lookin good, glad it fitted with no dramas, I like the top mount spacer idea. Let us know how you get on with the shock on the road and what settings you are using if you have them to hand, would be interesting.

Sorry to hear that, I wondered about your injury but didn't think it'd be as serious as that. Wish you a swift a recovery as possible. On the upside, it's a opportunity to fettle your bike so you have more to look forward to once you're back in the saddle  :)

I was concerned that my plan to remove the swingarm for a good scrub and regrease whilst i was at it might be a bit too ambitious for the back, but I was surprised and marginally alarmed that the nut came undone fairly easily.

I can ride.  But as the injury affects the left side of my body, I cant absolutely guarantee that when I come to a halt, i'll be able to put my foot down and support the bike.  I'm sure 9 times out of 10 it'll be fine, its that 1 time that bothers me.  sometimes when I'm walking the left leg decides its having none of it... always a laugh that one! :D

Am off work this week :)  maybe i'll take her out tomorrow

If you take out the upper peg hanger bolt and crack off the lower bolt you can push it to one side making the preload adjustment a doddle with the c-spanner...

Faulkner 725lb
Dog Bones were 127.5mm (I think)

I'm roughly 85kg geared, plus I usually carry a load

Preload position 3
Rebound 13 out
Low Speed 13 out
High Speed 2 out

Took it for a ride today, only a 25 minute ride.  It immediately felt much better.  I didn't give it the beans, because the tyres are still fresh (I laid the bike up 50 miles into a new set).  Also because I'm not confident that the bolt I used for the top mount is really up to the job, it was a normal Wickes M10x80, not high tensile.  I'm going to replace it with a high tensile or Ti bolt for peace of mind. We did hit speed limit +/- 10% on some country roads though.

More importantly, I was able to assess my own ability to safely ride.  It was hard getting on the bike, it was hard getting off the bike, and in all honesty, it was hard transferring my weight around to properly ride.  So I think I need to wait a little longer.

On the plus side, the bike started first click of the button after a month laid up :D

Next job - adjust the clutch cable at the engine end.

Just a quick note to say mine's fitted and has a few hundred miles on it now. Currently running default settings from Jeff:


"Setting the high/low compression damping at 4 turns out from full hard on the yellow high speed adjusting nut, and 16 clicks out from full hard on the low speed compression blue screw worked well for me, and my weight. Rebound damping i have set at 16 clicks out from full hard, and that worked well, also.


Preload is set midway, I haven't properly measured sag yet but I've not bottomed out yet so it can't be far wrong. Running a 675lb spring, I'm a couple of pounds over 14st when fuller clobbered up.


Impressions are it's a very worthwhile upgrade, even though I spend 75% of my time on motorways the old shock was still bouncing around in a rather undamped fashion, things are nice and smooth now. I've also got EMUs fitted to the forks and I was wondering if they actually worked but it turns out the old shock was so bad it was masking the front. With the new shock I can actually feel the front working properly which is a bit of a relief.


Cheers,
Rob

Hi all. I am new to fazer ownership and I'm looking into carrying out the r6 damper conversion.
What is the reason why the r6 damper with the separate adjustments nuts/screws won't fit on to the fazer??
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 23 July 2014, 06:13:34 PM
Welcome.
The shock's bottom mount is the same, but the top mount uses a 10mm diameter bolt whereas the FZS600 uses a 12mm diameter mounting bolt. 
The R6 shock's top mounting hole is only 30mm wide whereas the FZS600's top mount is 40mm.
Lengthwise, the R6 shock is shorter than the Fazer's, so you need different length dogbones.
Finally, the shock linkages / linkage ratios are also different, so unless you're 8 stones or less you'll need to replace the standard R6 spring with a heavier one.   
Title: Re: R6 rear shock on the FZS600
Post by: mac1984 on 23 July 2014, 10:04:35 PM
Thanks for the info. I think was yourself who posted (on a separate post) two photos of r6 shocks and said that one wouldn't fit on the fazer "even with a hammer!"
Why won't that model shock fit the fazer (separate adjuster version)? I only ask as ive seen a few of those on eBay for sale? I would find a photo of the shock I'm on about but I'm on my phone and it's prooving awkward to post a photo!
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 24 July 2014, 06:24:54 PM
Oh, that was Luke / DevilsYam's comment, and although it related to fitment on the Fazer 1000 it sadly appears to apply to the 600 as well.

1999 - 2005 R6 shocks have the circular bottom shock mount so the linkage mechanism to the swingarm is different from Fazers.

The 2006-07 shocks have the same bottom mount as our bikes, but the top reservoir layout (separate high and low speed adjusters)  forms a large body that interferes with / fouls the frame.  That was the version Luke / Devilsyam referred to in his hammer comment and probably the one you've seen on ebay?

The 2008-2014 shocks have a combined high/low speed reservoir (look for gold outer and blue inner top adjuster) and magically fit both the FZS1000 and 600.
Unfortunately these 2008 onwards units have become the rarest versions on ebay and are becoming more expensive as they can be adapted to other bikes including Bandit 600s & Suzuki GS500s (!)

Ah that's a shame. Again thanks for the info.
Just bought the right one from eBay. Does the different colour spring indicate what poundage it is?
Are you still stocking/sourcing the correct dog bones etc for the conversion? I'm around 14st kitted up so would guess I'd need to be up near the 700lb spring rate to keep the correct sag?

Yeah I'll have all the bits needed for a conversion 'back in stock'  :lol shortly, don't have a 700lb-inch spring, only a 675lb.  Send a message to Robbus as he's around 14 stone and from memory there's a 675lb spring on his.

Post by: mac1984 on 28 July 2014, 04:35:29 PM
Cheers Dcurzon. I was thinking about 700lb would be suitable for me as I'll never have a top box or luggage but will occasionally take the missus out on the back. Maybe worth upping it to 725lb. What was the standard fazer spring rate? I know direct comparison can't be made as the r6 damper is shorter etc. I've PM'd kebab19 about getting conversion bits.
Can't wait to sort the saggy arse end of my fazer. Then I can fit the r1 front end I've got turning up soon!  :D

I don't think you'll be far wrong with either really. The 725 will give you more preload adjustability with the mrs.

I'm going to fit my r6 suspension and dog bones soon. Is it a fairly straightforward job with it up on some paddock stands or do I have to remove the swing arm to do it?
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 18 August 2014, 05:45:02 PM
If you have someone to help it's easier for the two fiddly bits - top mount and lining up dogbones with holes.

Don't use paddock stands, put her up on the centre-stand.
Have your new shock's compression / rebound settings in place before installing it.
Completely remove the shock linkage knuckle underneath, drop out old shock & insert new shock up through the swingarm hole. Attach the shock to the top mount.
Grease the shock knuckle linkage bearings and refit the knuckle to the frame / shock lower mount. Fit the new dogbones.
Tighten everything and then check all mounting points again.

Hello Fazer owners,

Can you please confirm that the shock from a 2007 R6 won't fit in the FZS600? This is the previously mentioned version with separate adjusters. I could have it for cheap from a friend so I am curious.

Hello and Welcome.
Originally the R6 shock mod was conceived for the Fazer 1000 & those 2C0 shocks definitely don't fit the larger Fazers.  To my knowledge, no-one has tried to fit one of these versions to the 600.  Personally, I think they *might* be persuaded to fit with a bit of alteration but there's really not much room in there.
The problem will be that the top compression reservoir is wider / longer than the correct 2008 onwards version of the shock.  You might even have to take the swingarm off to drop the shock down into position within the swingarm, then bolt everything at the back-end on again.  So, quite a lot of grief and after all that, it still might not fit.

Ok, so I went with the proper version of shock with the adjusters together. Managed to get one with 3600 kms on the clock from german ebay for only €70. Great price, huh?

Shocks swapped yesterday night. All is well except that I can't seem to find an affordable replacement spring here in Hungary. Hyperpro, Wilbers and Öhlins are available but with extreme prices. Faulkners' is £31 which would be ok, but postage is £39... :rollin

I am 85 kg without gear and often carry passenger and sidecases. At preload pos 5 rear sag is 13 mm higher than the original one with the same preload (both without gear etc). I am considering buying a 750 lbs/in (131 N/mm) spring. What do you think?

Thank you all for sharing your experiences. Especially thanks kebab for the original post and DCurzon for the top-hat spacer idea and measurements. Exact fit.

You'd probably need either a 700lb spring or 725lb if you plan on taking a pillion.

Cheers to Brooker for a good sale on one of his R6 shocks.
Also for getting some top hats fabricated.
Also cheers to Kebab as he has managed to find his original alloy preload spacer plus some suitable top bolts.So all i need now is some custom dog bones and i have a full fzs600 to R6 shock conversion kit.If anyone fancies buying the other shock we can probably figure something out with getting a copy of the spacer made up. 8)

I would be interested to know what weight springs folks plumped for and their fully togged riding weight and whether they carry extra weight in the form of a pillion or luggage.

I am as near as damn it 14 stone fully togged including helmet, boots, jacket, gloves etc (Maybe  5 or 6 lbs under now, I have been avoiding the Jaffa Cakes) and Nitron fitted a 600 lbs spring on their R1 shock they made for me.
(The Nitron R1 has no connection to Yamaha's R1, I think it just means 'Road 1')

I have to admit to being very pleased with the shock and I feel that Nitron got it right with the spring weight, mind you they have been doing it for years.

The rider Sag both back and front are on the sporty side of normal,
Rear Static Sag with the Nitron Mono-shock fitted
= 16 mm
Datum set on seat fairing at 450 mm Un-laden from underside of rear axle thread.
Static Sag measures 434 mm from Datum to underside of rear axle thread. =16 mm Static Sag 
Loaded Sag Rear=37 mm(Fully togged to ride) Finalised
Front Static Sag with YSS Emulator & Ohlins 8.5 N/mm SV650 Springs
= 25 mm
150 mm Fully extended forks between the underside of lower yoke and the top of the fork seal.
Loaded Sag Front = 41 mm (Fully togged to ride) Finalised

I don't often carry a pillion and when I do it is either the Mrs or my Daughter either of them weigh about of them 8 stones, the bike has never bottomed out with a pillion and both the Mrs and Daughter say it is a much better ride on the back since the shock was changed, all I know is the handling inspires confidence now and with the front fork work that I did with a lot of verbal help and encouragement from Kebab19 (Jeff) the bike is transformed, chicken strips reduced, but i have noticed that the front tyre has feathered quite badly (Both sides) but I think that is down to it being a Batlax 021F, I believe they have a reputation for feathering.
I have a Battlax T30 Evo awaiting fitting and will have it done in the Spring of 2018.

Just winterising the old girl now and she will not come out again until the end of March 2018.

Evening all


I'v just picked up a near mint Fazer 1000 rear shock (1st gen i believe) at an absolute steel of a price I'v always wanted to do away with the standard 600 shock but i can not afford to do the R6 rear shock upgrade, £30 for the Fazer 1000 shock i paid it looks mint and apparently came off a bike with only 22k on the clock so i thought I'd be able to get my money back on it if i can't get it on, I'v been doing so much searching but i can't find a definitive answer about weather or not the Fazer 1000 rear shock will go on my 01 plate 600 ? can anyone give me some insight on what mods are involved to get this on my bike? i don't mind if it needs a little persuasion but i don't really want to have to file or grind out anything on the bike it's self to make this shock fit, i do have someone with a lathe that would make me up some spacers or bush type things if need be!

There was some info on the old Yuku site about this.
Yes, bit of a squueze but it'll fit, apparently.
You'll need to swap the heavier 600 spring onto your 1000 shock if keeping the standard linkage unit. You also need to do something with the coolant reservoir - don't remember whether it has to be relocated slightly.  You will also need revised length dogbones as the 1000 shock is about 5mm longer than the 600 unit

Why do i have to change the springs over? was hoping i wouldn't have to do this as my 600 spring has gone all rusty and the powder coating has started to flake off which makes it look really tatty, at the minute i have dog bones on that give the rear end a 30mm rise but i wanted to switch back over to the standard dog bones when i fit the new 1000 shock, i'd a thought it could be done right?

R6 or 1000 Springs are way to soft for the 600.

600 spring is 14.7 Kgf/mm
1000 spring is 7.5 Kgf/mm

You *might* be able to get away with it if you also use the FZS1000's linkage instead of using the standard 600 linkage.  But will it fit?  Dont know, the few who have used the FZS1000 shock have all swapped the spring over ...and with buying a linkage and revised dogbones, it won't be such a bargain anymore either.

If you stick with the 600 dogbones does it raise the back end up.
 If so by how much does anyone know...

 
 
 
 Just found the post on the old Yuku site and it does not mention the need to replace the dogbones.
 Just had a read and other than swapping the springs over you need to do the following:
 
 
 The spring collet retaining washer on the thou shock needs to be reduced in diameter also plastic spring seat reduced, "bench grinder" also the spring tension adjusting bracket will have to be ground away "angle grinder" on the side away from the gas can otherwise it will wear away the coolant overflow tank

I was going to replace the coolant with waterless coolant and then do away with the expansion/overflow tank.

So I will not need to do any of the above.

Unless the bits that need grinding foul on the swing arm I hope not.

found this also which also explains the mod
http://foc-u.co.uk/index.php?topic=5396.0 (http://foc-u.co.uk/index.php?topic=5396.0)

With the addition of this minor adjustment. The shock top mounting lug on the frame needs a little grinding out on the underside because the shock fouls the bracket., (a millimeter or so) to get the bolt in. Then just touch up the frame with black enamel

As you probably all know, I wouldn't discourage anyone from swapping shocks over  :lol

But there's a reason why a huge percentage of FZS1000 owners swapped their standard shocks out for R6 units - and that's because it's not that great (unless of course your existing 600 unit is completely and utterly b0rked).

Hello guys, ordered R6 (2011) 13S shock from fleabay.
Will fit it to 2003 Foxeye (600cc). I know that I need spacers for top (from 12mm to 10mm bolt) and dogbones. Anything else?
Would be much grateful, if you can provide me with links/contacts to where I can get these items.

Thank you  8)

I have the 1000 shock on mine and to fit you need to fit the 600 spring and also grind / file the top mount on the frame by about 1 mm to let the shock mount properly also you need to move the expansion tank behind its mounts to give clearance or the spring adjuster rubs it . As for performance I can't fault it it may not be as good as the r6 shock but is a easy fit and a decent upgrade since I have fitted it I have not noticed anything untoward with the back end so it must be doing it's job ok

Dunno if anyone is still considering this shock conversion anymore, but if so I have a small addendum.
As mentioned a year or two ago, I found that it is possible to fit one of the earlier 2006-07 R6 rear shocks to the FZS600.  This is the shock with two separate top adjusters (anodised gold and blue). 
The advantages are:
1 - It will not fit the Fazer FZS1000, meaning: 2 - It is usually unloved and unsold on ebay, not to mention generally cheaper.To fit it to the FZS600, the same conversion parts are needed as per detailed on this thread, but you also need to file a tiny amount off the top of the shock to get it to fit, as per picture below. This groove on top stops it from fouling the frame's crossmember above the shock.  There was no point in taking a picture of it in position as frankly you couldn't really see the interference between shock and frame.

Kebab just a thanks for giving me your last bits and pieces to do this


I’ve only just got it on the road so I think the conversion will need to wait until next year but I look forward to it and in the meantime if I come across anyone locally who can copy the bits I might get a few sets made up just so as to keep the conversion alive...well at least help.👍

The newer R6 shocks (starting with 2008) are really quite expensive and I'm considering now buying  a 2006 version. Please check attached picture:   :)
s l1600

Does it kinda make sense to buy that thing including the linkage?
You have mentioned that something needs to be "filed down" from the 2006 shocks? Do you have a picture of that or where that "problematic zone" on the shock is?  :rolleyes


Thanks.  :smokin

Ok. Found an 2008 R6 shock (basically unused) ... price seems fair.  :rolleyes


I kinda have already an idea where to get those top-hat spacers and the dogbones might also not be a problem.
But are the spring spacers mandatory (if I'm going with a 6" spring)? Are some suitable spacers somewhere available on the market or do I also have to let them fabricated?
Or has anybody tried to fit a 7" spring?


Thanks again.

Heho.


I did some research for parts ... And I came across these top-hat spacers.


https://www.ebay.co.uk/itm/M10-to-M12-Shock-Absorber-Rod-End-Top-Hat-Step-Reducer-Rose-joint-Kit-Car-Spacer/332781563553 (https://www.ebay.co.uk/itm/M10-to-M12-Shock-Absorber-Rod-End-Top-Hat-Step-Reducer-Rose-joint-Kit-Car-Spacer/332781563553)
Not sure if they fit but I'll give it a try.


I've also found some dogbones (128 mm) here:
https://www.bikefarmmv.com/epages/79512538.sf/en_US/?ObjectPath=/Shops/79512538/Products/%22HHLZS%20128%20MM%22 (https://www.bikefarmmv.com/epages/79512538.sf/en_US/?ObjectPath=/Shops/79512538/Products/%22HHLZS%20128%20MM%22)


Will most likely go for a 6" spring ... sadly I didn't find a suitable spring spacer.
So I kinda need to fabricate that one on my own. Should I make it out of a 12 mm aluminium plate?


Thanks.

An ID of 10mm will take a 10mm OD pin screw, because the OD will always be very slightly less than 10mm eg 9.95mm or thereabouts

Im finally getting round to fitting one


I have kebabs dog bones and spacer and i had top hats made up


Just ordered a 725lb faulkners spring


Just curious about the filing of the top of the shock mentioned earlier......is it still neccessary?.


Also that collar above it looks like it has been fitted on top of the spring and is much taller than the one i have from kebab, i thought the spacer went on the bottom of the spring?


Main reason im here is that this site is a far better resource than facebook, i feel like facebook has robbed this place even though im on the facebook site......this thread is invaluable

Yay, the mod lives on  :)
The filing mentioned above is only for the 2006-07 R6 2c0 shock: if you have one of the 13s (2008 onwards) shocks as per picture then no filing is needed.
Spacer can go on either the top or bottom, most people prefer it on top of the spring.
Thickness - well, the Faulkner springs are 152.5 mm long whereas the original R6 spring is about 165mm long. So the extra spacer is to take up the missing spring length.  It can therefore be between 10mm - 15mm thick, depending on how much preload you want on the replacement spring.

I agree. I think facebook has killed off forums in general as a platform not just this one. People do their day to day general posting on facebook and only come back to specialist forums like this one when they have a technical question. Then when they get their answer they head off again. It's a shame but there's not much you can do about it, people will go where they want

No, his shock is the 2008 onwards version that doesnt need any grinding. You can tell by the shock's top compression adjusters - both are contained  in a single unit (outside one is anodised blue and the inside adjuster anodised gold).
The shock that needs modded slightly at the top is the earlier 2006-2007 R6 shock - it has two separate blue and gold compression adjusters.

No, no grinding needed. I've needed a lot of patience to get the top-end of the shock in place.


BTW ... maybe one additional question I have. On the top I've used a M10 grade 8.8 steel bolt and a self-securing nut (steel inlay) - that's good enough?

Hi all,
Im new to this great forum and REALLY like all the wisdow it has !
I live in Sweden and getting the right springs and shocks is quite hard...
Forgot to mention I have a 2002 fzs 600.


I have an ad  in the sell section but no luck yet...
A few questions about the suspension mods on this bike:
Is the R6 (o8->)still the shock to use?
Is there a spring that would fit a 95kg without the need to fabricate a spacer?
A fork spring question (I know not the corret thread..) some have used VFR750/800 springs in the fork, what year and modell and what weight does it work for ?
I live in Ohlins country (Sweden  :rollin [size=78%])but its hard to get suspension help out here....[/size]

Hi, first time posting on the forum, even though I've been a member a cpl of years. I think I'm guilty of the Facebook thing as It's easier...


Two part question...
1. (Relevant to this thread) Do you still make up these shock mods or supply spacers n dogbones?
2. (Not so relevant to this thread, but I'm gona ask anyway) when it comes to changing the spring on the R6 shock; how do you know what "weight?thickness?strength???" of spring to get to be able to adjust for the weight of rider (one up), rider & luggage and rider and pillion?


why is suspension set up such a dark art... or is it just me  :look [size=78%] [/size]

Hi, I'm also interested in the dogbones/ spacers if they're available?
Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 07 May 2019, 07:30:54 PM
Hello,I don't have a 600 anymore and sold all my spacers / dogbones years ago. The dimensions of all the parts needed are listed on this thread, you'll have to track down someone with a lathe to fabricate the parts. Don't try & ride with the standard R6 spring if you're more than 7 stone weight or you'll end up in a hedge (at best).

Spring length - the R6 shock has an unusual 6.5 inch spring.  Aftermarket shock springs are (pretty much) only available in 1 inch increments - a spring 5 inches, 6 inches, 7 inches, 8 inches etc.  If you install a 7 inch spring there will be a lot of preload on the spring, even on the minimum preload step. If you install a 6 inch spring there will be very little preload on the spring, even on the maximum preload step.  Hence the need for a half inch spacer to take up the difference. If you can find an aftermarket manufacturer who can make you a 6.5 inch spring then this is not an issue...but good luck with that.
Spring rate - when I was selling these shocks, I found the following rates most suitable:12 stone rider - 625lb per inch spring for solo use, 650lb if a lot of pillion work / hard luggage or fast road riding track days14 stone rider - 650lb per inch for solo use, 675lb with pillion / luggage / fast riding16 stone rider - 675lb per inch for solo use, 700lb with pillion / luggage / fast riding
etc etc

Dogbones - don't try & raise the back-end too much - there's the strong possibility of dogbone-to-swingarm impact you go shorter than about 124mms between the dogbone hole centres. I stuck with 127mm bones.
   
Happy modding  ;)

For what it’s worth, I find the R6 spring gives an excellent ride. I’m light, though not 7 stone… more like 9 and don't carry a pillion. Sag was (just) within the prescribed range.
Doubtless for track use it’d need a stiffer rate, but on the appalling roads round me the standard spring is easier on the spine. :lol

Any idea if 130mm dog bones would be a massive difference from 127mm? I've found some generic ones on eBay for a significant amount cheaper than I can get 127mm ones made for!


I can also get 125mm but this would raise it too much?







Title: Re: R6 rear shock on the FZS600
Post by: kebab19 on 04 June 2019, 09:20:57 PM
130mm dogbones will work fine, it was one of the length options of my four length Projection Components dogbones.  I think the 127s gave a very slight tail-end lift, whereas 130mm should be more like the standard height.

Awesome, just bought the 130mm ones so I'll let you know how I get on  :D


I bought some generic top hat spacers on ebay for a few quid, but I think they're 1mm too wide as the shock won't fit in so need to file them down 1mm each.  :'(

Finally found the pictures to update.   2C0 shocks just require a tiny bit of filing on top - stops it fouling the top frame brace.

As the R6 shock is only 10mm too short I don’t think that adaptor would sort the problem, you couldn’t have the two mounting holes that close to each other.

Post by: mobile mouse on 05 March 2020, 08:02:27 PM
Help required.
can someone tell me what the bolt size or sizes are for the suspension linkage.
2x for dogbones I assume they are same length.
2x for shock attachment M10x???mm (what length some say 75mm) top bolt for R6 shock I assume the bottom bolt is the same as std bolt.



The std dog bone bolts measure as 130mm long, the dogbones i have for the R6 shock are (127mm) these are 8mm thick.
Std dog bones are 6mm thick so is there enough extra on the std 130mm bolts to take the 8mm dog bones.
Or do I need to buy a couple of bolts 135mm long, if so what M size are the bolts.

MM - did you get a spacer made up or acquired one from somewhere? I'm getting unfeasible quotes of £75 + from CNC places

The spacer came with the shock already fitted. Sorry to be no help.

Thought I would give people a  :lol  and add to this topic. Got all the upgrade parts but not the spacer - quotes for this ranged from £87 - £165 for a basic bit of drilling an aluminium billet! So got a billet from evilbay (£4) used a hole saw to cut centre and axle grinder and file to reduce diameter and shape a lip to fit preload adjuster.
What a unsightly monster it is but .....works perfectly  :) :)
