Thanks for that :thumbup
No it doesn't say anywhere on the spring & I don't have a manual
The reason I'm asking, is that I have just adapted a sachs rear shock to fit on my sv650 k5.
I rang K-Tech and they said they thought it was a 95kN.
I've fitted it with the original spring, which has made an unbelievable difference to the rear end. It's still a bit choppy on high speed bumps.
I could do with a 85kN spring though to try and inprove things further.
