I had a chance to ride a 450r a couple weeks ago in pismo. This one had nothing but a big gun slip on and a jet kit. I couldn't believe the power that thing has in stock form! It had so much torque you would have to really be trying in order to kill it from bogging. My Banshee was able to beat it up comp hill and on the flats several times but it was by only a couple feet each time...and I had better tires. The 450 is amazing....now I know why they cost so much. The only thing is that they are waaaay small for a guy my size (6'3" 235lbs).
