I just won a ZX10 shock on ebay a 08 with an aleged 25 miles on the clock.
Can anyone point me in the direction of the bolts a require to fit this to my 2000 plate curvy?

I think i found the bolt that i need http://forums.sv650.org/showpost.php?p=1565148&postcount=34
Has anyone tried fitting a 08 shock to a curvy as they appears to be diffrent to the <08 shocks?

That spring doesn't look like it has as much coils as my zx10r shock. Anyone got the spring rate?

I may have the bolt in my garage.

So has anyone used this type of shock on a curvy SV?
Going to get some quotes today for the fitting.

You got a torque wrench and a way to jack ya bike up NOT from the swingarm?
If yes, not too hard to do yourself

Do it yourself. I wouldn't trust any mechanic to do this type of modification work. I researched quite alot before doing mine.
I am still concerned about the spring rate, been trying to find it out but it seems its a secret :) You could run the risk of having a significantly softer shock than the curvy standard. Maybe you should call Kwakasaki themselves and see if they can tell you the spring rate.

But, if your a complete tool, you end up doing a worse job

In all honestly what are the chances of that happening!

Quite likely, most late GSXR shock are softer than the Curvy's. The pointy's shock it significantly softer than the curvy.
I suppose Plowsie is right if you are a complete tool you may **** it up but if you have some common sense, the right tools and time to research properly you will stand a better chance.

The SRAD 750 shocks are very soft, but do work pretty well...

Highly likely, My Busa shock Pre-Load was pretty bad when I first sat on it, really fell under my ****, so I adjusted it :)
but surely the dampening will be that much stiffer that it needs to softer spring, i cant see how a shock from a zx10 can be worse than that of a curvy.

What? Stiffer spring generally needs more rebound, I would assume a top flight sports bike designer would be fairly well aware of that before having showa (iirc) create a 3 clicker shock at great expense....
Shadow. You're pretty much on your own with this shock since I don't think anyone has done it yet, call up some suspension tuning places, ask them if they'd tell you what spring the -10R shock has. Compare this to the table Mr speirs posted up earlier.
It looks like it will fit, and you will have lotsa fun with high and low speed damping settings to play with lol.

i wasnt questioning the design of it, just trying to get my head around why a sports bike would have such a soft spring.

Because the effect of the suspension linkage / swing-arm length / bike weight etc will dictate this. A sports bike's suspension may feel firmer and need more force to move it a given amount, but that is not due only to spring 'strength'.

Because the spring is only part of the equation, the linkage geometry and weight bias of the chassis all have just as important an effect on the force needed to move the wheel around.
ah k cheers, wont ask such a question again!

Now go and sit in the corner and think of what you have done! :roll:

Feel free to ask away... your wording threw me a little.
Above you put "how can a ZX10 shock be worse than curvy"
Good/bad isn't just hard/soft. You could use a shock from a ZX10 (not the zx10r) from late 80s. It would be shoite! It's as much the quality of materials, the complexity of the valving arrangements etc.
A shock from a 125 GP bike would probably be very under specced for the SV, maybe too soft or not enough travel/length. That doesn't mean it's a bad shock, as it's probably had hundreds spent on getting it set up... not a bad shock just not set up for an SV...
Yeah my wording probably showed my confusion in its vagueness! never occurred to me about the linkage and swing arm making an influence but makes sense now.

I feel i might have some searching to find those spring rates , going to put some posts on kwak forums.
EDIT
I think i have found the spring rates on racetech.com #510 so should work. The problem i think i will have now is with fitting it , i didnt apreicate how much of an angle that resoir on the shock is at. Ill post some pics when i recieve the shock. #-o
Do you think i will have to move or alter parts of the bike to make it fit?

Yeah, cut the front of the battery box out, get rid of the fusebox tray, space the battery up to fit.

If I remember right theshadow has a dodgy knee and I wouldn't want him to strain it again doing a runner :-P

You can get the spring rate if you enter the bike details into
http://www.racetech.com (http://www.racetech.com)
click top right SEARCH ... and then "search spring rate"
the spring rate is craftily hidden down the page rated in kg/mm.
Most of the info on this forum is on lb/inch with figures 400-530
The page i've put uses kg/mm so just
obviously * 2.54 to get to inches * 22 to get g/lb
