Just to push the boundries, I've decided to try to fit an Aprillia RSVR 05 rear shock to my SV650 K5.
Q. Why?
A. Every one's fitting GSXR/ZX10 rear shocks, but can anyting else be fitted? even if it costs a little more or requires a little more work.
Q. Will it fit?
A. NO. It's too short, it has a rose joint on the bottom instead of a clevis and the spring rate is too high (unless you weigh 26 stone
).
I've looked on RSV forums, and as far as I can tell, nobody can tell the difference between an Ohlins or a Sachs on the road, so I thought I'd give it a try.
Bought off Ebay for £37, the Sachs rear shock comes with adjustable compression damping, adjustable rebound damping and adjustable ride hieght.
The gas resivoir seems to be a little bit lower then the GSXR or the ZX10 shocks, so with a bit of luck I will not have to modify the battery box.
As the shock has adjustable ride hight, I thought I could unscrew the lower rose joint and manufacture a clevis to fit that would increase the shock length to the same as the original, be a perfect fit for the lower fitment and retain the ride hight adjustability.
the first thing to do was to remove the spring.
I've looked for the spring rate on the internet with no results, but measuring the the spring, I estimate the spring rate to be 580lb/in
I think I need a spring rate of 470lb/in (8.4kg/mm) approx.
The spring appears to be the same dimensions as the Ohilns(57mm ID x 160mm long), so the search is on.
I then had to remove the lower rose joint.
The rose joint has a spring loaded pin protuding through the side of the thread, so once screwed in, it can not come out
There is no provision to depress the pin before unscrewing the rose joint, so I bit the bullet and got a bigger spanner.
The result was, the rod end came out but took all the threads with it
From a quick look at the threads, I think the original thread was M18 x 1.0, so now it's stripped, I will hopefully be able to re-tap it 3/4"unf and make a clevis to suit the bottom mounting and the linkage.
