along with a crf450 i have an 05 RM-Z450 and i love it. i let my friend ride it (he loved all the power and he really liked the handling) so he went out and bought an 06 RM-Z450, he called me pissed because he says the bike handles horribly he says it won't stay in ruts, doesn't lean, and it washes out everywhere. any suggestions on what is causing this or how it can be fixed
