[QUOTE="Jasle, post: 1231286, member: 26675"] well the rm is about .5" taller than the kx. the KX seems to have more topend than the RM. KX's at the track seem to eat cranks. Same as the 65's. RM's before 06 were cracking frames up front right near the pipe mount. Probably not an issue for a trail rider but something to look for on a used bike. We cracked 2 ouf our 3 RM's. I had them rewelded from a guy that is a quality welder. Never cracked again...Still running them too. We race...a lot though. Mx and the kid is a jumper. Its hard to find a flywheel weight for the RM though. R&D has a killer upgrade for the powervalve for the RM. Huge increase in bottom end power output. Kinda spendy though. Really changes power curve. almost 2hp in the lower end. Nothing for topend. just keeps powervalve closed longer. Not exactly a 4 stroke but way better than stock. save the money on the pipe and reeds and you break even with more difference. [/QUOTE]
