My traxxion fork cartridges are arriving next week and need to sort out my rear spring rate before installing everything. I picked up an KA 502 ohlins for an 05 Zx6r and it came with two springs. The installed one is a 1093-29/90 rated at 9.17kg 514lbs and the spare is a 1093-39/110 at 11.21kg 628lbs. I am sure something in between would be ideal for my 185lbs w/o gear, but wondering if either are suitable, or should I purchase another. I would ask the guys at traxxion, but they are out of the shop until the 15th.

Thanks!

I'd suggest digging through the stoltec project bike thread to figure out the stock spring rate and go up from there. If my memory serves me I think the 514 is too soft and I think the 628 is too heavy but probably better for your weight than the 514. It probably depends also on your riding style but somewhere around 575-600 would be appropriate, but again this is just from memory, get someone who knows what they are talking about.

A quick search on the racetech site shows that my 2006 zx6rr shock came stock with a 10.3kg/mm spring which converts to 575lbs/in. I'm 200lbs with gear and its just right for me. Hope this helps.

9.4 kg/mm should be enough for you. You could get away with the 9.1 with a rider sag of 33-35max. That's what I use, the 9.1 kg/mm. I'm a hair lighter than you and I'm at the limit.

I think those are my #'s too -- same as yours.

Just got back from a 40 mile ride in West Boynton and Lake Worth. It's 88F and NoT one Cloud in the sky today. :cool:
