I recently picked up an '03 WR450 that is in pretty condition except for a leaky fork seal. My mechanic says the fork is lower is too pitted from rust to allow a good seal, and a used fork tube may be the way to go. So....I've been looking around for a set of good used forks, and I found some that are from a WR250f of the same year. Will these bolt right on? I checked the online parts finder and they are different part numbers, but both are supposedly 46mm Kayaba. I have heard the only real difference is that the 250 is sprung slightly softer, which is a definite downer for my 200lb frame. Are there any other real differences? Any help will be appreciated!
