Re: 954 fork spring rate
A pal of mine is chopping his 954 (gearbox failed - lost 3rd gear) in against a GSXR1000.
Anyway he has some goodies that I might be interested in, including some upgraded forks with RaceTech valves and springs. Do a straight swap with him. My standard 954 forks for his, plus me giving him $75.
However I am a little confused about the springs he has fitted to the forks. He tells me that they are rated 0.8kg/mm.
These forks were put together by a Brit Superbike mechanic who certainly knows what he is doing. He's fiddled with the shim stack too (whatever that means ). I might add that pal is serously fast, he ought to be racing. Very, very quick.
I was surprised because when I upgraded the springs on my 929 I went to .95kg/mm and I'd assumed that the 954 would be the same or very similar.
So I checked the RaceTech site and did the spring selector thing. On that site it suggests that stock springs on both 929 and 954 are rated 0.7kg/mm. Not what I understood at all. Further, for my weight, it suggested going to a 0.8kg/mm spring. Odd I thought.
So what gives? Do RaceTech measure in some different way or is their spring tester knackered?
Help/advice please. Thanks in advance.
