I picked up a used 2002 wr. I weigh 290 lbs ready to ride. I have been looking for the right spring or something close for the rear. I dont do large arial jumps just the usual trail riding but I do ride hard. I cant seem to find a site that can give me an idea as to what spring to get. Anybody have a link to a site that makes sense of the spring rating for fat old folk like me? Where to buy?
