I've got an M50, too (as Pinhy knows...). The C50 and the M50 have the EXACT same frame, engine/tranny, shaft drive, exhaust, FI, side covers.... the only difference is the front forks, tank fenders speedo and the handlebars/triple trees, rims & lights. I believe the M50 weights a little less. I can't tell you if the front wheel would come off the ground or top speed, I haven't broken mine in yet and am not about to risk screwing it up. Don't think I would try a wheelie anyway....
