This is out of my 1999 SV650 front forks, can anyone tell me what the spring rate is? A couple of people tell me the rate is stamped on top of the spring but all I see is that little "b" symbol? Ideas?

I believe that is a 9... indicating that it is a .90 kg/mm spring

Thanks Corson, that would make sense. I had the same thought but it looks so "unofficial", didn't want to just guess. Someone on the SV Rider forum said the same thing, I have an email in to Racetech, if they concur I am going to go with that.

It could be marked .90 kg/mm but who knows if it really is .9 kfg/mm. Are you wanting to go stiffer or something?
