If I had to trade my banshee for a 4 stroke, I would trade for the YFZ450. But I dont have to... Cuz I already have a 450!! The Cannondales dont seem to run all that great in my opinion. A guy that hillclimbs at the same hill we do owns two of them, and he never seems to do very good. Ive never ridden one, but by watching him, they dont seem to scoot too well.
