I have heard the SC500 was a pig but in the hands of a seasoned rider it performed well. I think the trick was to keep the throttle pretty much full on and it was happiest. My 360 is enough of an animal with its limited suspension and poor brakes. Any more power would be be insane.
Rumor is that Chuck Norris rode one all the way to Hell , Roosted the devil, Then rode all the way back performing a one handed wheelie.
