i have an 03 rm 125 and i haven't had any problems with it yet and its been about 20 hours on it but i've heard that they have bad cranks and bearings. has anyone else heard about this to and if so is there something to do besides change the tran. oil often, i do it after every ride but if i have to every 2 rides because i don't want to have worry about it.
thanks
