R6 rear shock on the FZS600

[mac1984]

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??

[kebab19]

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.

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!

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?

[kebab19]

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. 

[mac1984]

Excellent. Any chance of a price list for the parts required via here or PM or email? Take it's just dog bones, spacer for the spring and the top hat spacers for the m10 bolt? Will be glad when it's on there as I'm getting tired of my fazer's wobbly rear end!  :-)

Mac1984 - i'm anywhere between 12-13st naked so probably between 13/13.5st kitted, plus carrying in the top box.  I used a 725lb spring.
Preload position 3
Rebound 13 out
Low Speed 13 out
High Speed 2 out

[mac1984]

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! 

[dcurzon]

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

Hi thanks to Kebab19 I now have a well sorted bike.
Well I think I do as I really haven't put much mileage on her just yet.
The few miles I have done made her feel a lot more precise.
I will have to fiddle and tweak her to get the best out of her but she doesn't feel so saggy now.

[mac1984]

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?

[kebab19]

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.

[mac1984]

My fazer doesn't have the centre stand fitted from when I bought it unfortunately. Bugger!

[kebab19]

Do you have access to a pair of axle stands? Might do instead

[mac1984]

Indeed I do. I might take it all into work and do it there. Plenty of axle stands and ramps. Might look a little out of place though, in a workshop full of Aston Martin's  :lol

Go for the Aston Martin shock......seriously.......we won't tell anyone 

[mac1984]

They are made by Bilstein and nice units, but unfortunately too large and not to mention pricey (even with discount) for me!  :'(

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.
