I have a 2006 klx300r that I would like to try a set of progressive front fork springs. Would like some feed back on any who have used them. I also have gold valves for the front but have not very good results in the past with my kdx 220 cant seem to get a good stack that work in this Florida terrain.

 

Progressive suspension makes a spring which is very close. I've considered putting them on my 2007 KLX250s which uses the same suspension.

Basically you need 455mm long x 38.2mm circumference springs. PS makes one that is 38.2x462. 7mm longer isn't much, and cramming them into the shocks would work like 1/4" of preload.

 

called progressive. they will not tell me how to order that spring, and any info on it.... how did you get that?

 

I got my springs from ebay. I think they where the last set in the USA. I called progressive and they said they do not make or sell anymore.My set is in my 2006 KLX 300R. I put them on ebay quite some time ago got no offers.They will fit the KLX 250R also.I would make you a good deal on them but I broke my leg and cant remove them yet.
