Low mass and hard charging engine that peaks out at 12000rpm. If you can take the riding position, and many can’t, great fun. Engine should be smooth and quiet, if it ain’t then top end may be dying, though usually the bike does 50k. Signs of high miles are leaking upside down forks and worn tank paint. A lot of thrashed examples out there, easy to blow a stack of dosh on a dog.
