There have been guys talking about the lack of bottom end on the M7. A little clutching and a change of riding style compensates nicely.
I've heard this argument a few times from m7 owners and it always makes me chuckle. Why would you want to change riding style because you bought a sled that lacks bottom end? No amount of style will make torque increase. Ya you can raise your engagement r.p.m. but that's harder on belts, mounts and cranks.
Again not to bash the m7 because I really do think they were a great sled in their day, just pointing out one of their shortcomings for a newbie rider. m7 or 600 rmk is probably the best bang for the buck in the 5k price range for a newbie
