There's a CVT on this one, too. Normally, there would be just the clutch housing with the pinion right on the side of the engine. The CVT made it easier to line up the engine and rear wheel by pushing the pinion gear back inside the frame of the bike, so no need for a jackshaft. (And it makes the bike pull like a freight train because of the super-low gearing, almost 2:1.)
Hey, that horn cost me a whole eight bucks! (About as much as I paid for all those tire irons, actually ....)
