If it fits the Gen 1 1000, would it fit the FZS600 ( I don't have the battery/rear guard support no nothing in the way of the gas reservoir etc)
I hadn't heard of this conversion for the 1000 and thought my options were down to either an aftermarket shock, R6 (with all the complications) or keeping the standard one, so muggins here when for a Kawasaki unit, which would go if I fabricate a new top mount but the BMW sounds like the way to go if its more or less a bolt on, the ZX shock can go back on fleabay
Theres a brand new one on Bay atm for a 2015 S1000RR, just need to find out if its the right length, oh and if it would fit of course
-
Will physically fit, but spring will be way to soft. Fazer 600 needs 14.7kg/mm and I have been trying to get a spring to suit but the nearest I can get is 12Kg/mm.

Is that the BMW shock and is it a problem when your solo (I'm 10 stone wet and bike has single seat only)
Read so many conflicting reports on forums.....Grrrrrrrr

The design of the linkage, swinging arm and its location require a heavy spring.

Never bloody easy is it......
Thanks...
Back to the drawing board :wall :wall :wall

I had a spring made up for the R6 conversion by Gaz shocks (gazshocks.com) at 675lb and 6 1/2" in length. Cost me about £35 delivered. They said they could have any spec made up for tha. Then had the spring swapped by K-tech for the price of postage.
Just an option.

I found a place at Market Harborough called The Shock Factory, that can supply a spring for around £30, they're not far from us so am going to take the shock around and have a 16kg/mm spring fitted (assuming they fit springs to other shocks) still makes the unit about £80 cheaper than the R6 conversion I've seen on focu

With the shock designed for a BMW linkage with less leverage, does that translate to greater suspension travel when fitted to the Fazer? (Just wondering whether the bump stop will be reached before the tyre runs out of room above.)

50mm of shock stroke is still 50mm no matter which bike the shocks fitted to. Getting the spring right for the weight of the bike etc should prevent it bottoming out, as for hitting anything, something would have to break for my tyre to come in contact with tail piece
-
Fzs600 rear shock is quoted as 50mm stroke which I think relates to about 100 to 110mm at the wheel and BMW shock quote rear wheel movement on the spring of 130mm, don't think it will be an issue as it already drops the rear by 10mm due to the extra 5mm on the shock
-
From the posts I've read nobody complained about clearance issues just the sag induced by the weak spring compared to the Fazers.
Not sure what effect the spring will have on the damping but it has the usual hi/low speed etc so hopefully it should be set up to suit
-
Fair enough. It was just the thought that the two bikes aren't very different in weight or rear wheel travel… so if the BMW has a lighter spring it'd point to a small leverage ratio and a shock of correspondingly longer travel.
Of course, I'd forgotten that the linkage is designed to give a rising rate anyway, so wouldn't be affected much by an increase in available shock movement.
-
Well it fits, sort of. Lower mount clevis fouls the suspension linkage, not huge problem but will need some material filing off so it doesn't rub. Top shock mount far bigger than Fazer shock so again a little filing work required. Expansion tank would probably need relocating or substituting, the centerstand mount also fouls the suspension link (read somewhere another forum member had the same issue with a Nitron shock)
But apart from that it fits nicely..........
On bonus side the extra length and the 125mm dogbones gives me about 50mm lift on the rear

Nice work Joe, watch those filings, :pokefun they'll make you a lovely abrasive paste when mixed with your chain oil.

The chain's already at its limits so it's off in the bin when I get round to removing it. Just don't see the point of cleaning off the filings until I've finished with the grinder
-
Went into a local garage today to see if they can pop the spring off the shock, they couldn't do it there but one of the lads who worked there said his old man rebuilds car racing dampers for a living.
Going to ask him if he could re shim the shock and if so get a price.
Removing the spring for a couple of beers, me thinks the rebuild isn't going to so cheap.
-
Got these little babies yesterday, only 125mm centre's, very neat.

Picked up the shock from the engineers today, spring fitted and the top mount drilled out to 12mm, need to grind some material from center stand mount to clear the suspension linkage but should just bolt on then.
Cost so far is about £140 which includes new 16kg/mm spring and top and bottom spring seats. So not to bad. Could have saved a few £ waiting for a cheaper shock but one I found was like new. Not sure how it will handle but it looks the part lol
R6 is probably the best option though as even though this has worked out cheaperits not a bolt on, the expansion tank needs moving or modifying and even the shock body needed some filing.
One other job out of the way
-
Just waiting on the studs to be returned from the engineers (needed slight alteration) and I can fit my dog bones.
With the new spring I had to grind some material from the centre stand brackets to allow the knuckle to rotate forward to allow the longer shock to fit (the original spring was so weak I compressed it by hand to pop the bolts in)
But it's in and staying in for now, looks the part if nothing else, spend a few hours de seaming the suspension rocker before fitting it, came up all right, but bloody long winded job

I don't remember doing as much grinding when I tried fitting mine, before I realised I could not get a spring to fit.
Thanks for the info on the spring availability Joe.
I sent my 60,000mile Hagon Shock back to Hagon to rebuild it since it started to leak and they offered a complete brand new stainless body with Spring replacement for £160. Could not pass that up, fitted it a few weeks ago and it feels good, need to do a few more adjustments to get it to my liking.

With the stock spring on it wasn't a problem. the spring was weak enough to compress, therefore shorten the shock, not quite so easy with the 16kg one on.

Dog bones, sorry about rubbish picture
-
Take off the shock and turn the fork 180 degrees to allow easier adjustment of the rebound otherwise it will be obscured by the exhaust

Had turned it once but came back from the engineer who fitted the spring pointing in the exhausts direction. TBH one concern I do have is re the 16kg spring. No static sag (bikes very light) and hardly compresses when I sit on it, going to take some mighty bump in the road to bottom this one out.
-
Yep, You are going to have a solid ride, that is about 15% stiffer than standard on the 600
-
That is not going to handle right I think - that spring seems extremely stiff for your weight. Also concerned that you've put a much stiffer spring on than the shock was designed for - I doubt the damping is going to be up to the job of controlling the shocks movements with that stiff a spring!

Yeah, I understand the theory, thing is, I don't really give a dam, it looks about right, and, in my book, that cant be far off.
-
Fair enough if you're wanting to put the bike on a plinth and look at it, but I wouldn't want to ride it!
-
Would sooner have an over firm shock than one that bottomed out on every bump in the road.Front ends most important to me and the SRAD forks got some pretty decent press in their day
