I am putting new seals in a set of forks for a 98 RMX250. The forks that are on it are not the stock conventional but inverted ones. I thought that maybe someone took a set off a RM 250 but I don't know for sure. My 02 RM forks are 46mm for the inner tube on the bottom and the RMX has 45mm inner fork tubes on it. Anybody know how I can figure out which forks these are? These forks are not twin chamber and have a 30mm "bolt" on the top cap to remove it. The top tube is 54mm for the top clamp and the bottom clamp area is 57mm.
