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
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


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.

Hi


I'm just about to advertise a full rear setup for this very thing- R6 rear shock, dogbones, spacer and top hat spacers all there to fit an fzs600 1998-2003. I'll send you a message privately as well.


Cheers!

I have a question about the TOP hat spacer. The ID is shown as 10 mm. How do we then fit an M10 pin/screw. Or do we use an ID of 10.5mm?


Many 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

Hey everyone


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


Cheers

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

I agree Dude


And im guilty


I think its just how easy facebook is, just a click the phone and straight on although the humour just isnt the same and its not as good being able to look through everyones profile, much better the mystery and forum callsigns


For years i resisted the facebook site and on the whole i still dont find it as good........actually my tuppence worth is that foc-u should never have gone facebook official as it would have been better people starting up their own fazer facebook instead which may have left more on here.

Kaobiore did you need to grind anything off of the top of the shock to make it fit?, theres one comment somewhere about doing this?

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. Link to a 2006-07 shock below (hopefully)https://2fiftycc.com/index.php?resources/yamaha-2006-yzf-r6-rear-shock-absorber-adjustment.274/

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]
[/size]
[/size][size=78%]Cheers[/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?

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

I did originally fit the standard spring to my own and had a lot of fun on the maiden journey, until I upped the speeds a little  ;) and almost met the grim reaper a bit too early for my liking.

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?
