Cool Bike. Like it. The big difference from the 500 and other bikes, is that you use the bottom end power most of the time. What would be bogging the 125's and lugging a 250 is controllable power blasts from the 500. They are pretty dangerous when you try to ride the pipe, until you really get comfortable with it. you never really get "comfortable", I guess, more like, less freaked out

. 500's do wear you out, though, compared to other smaller bikes, but alot of fun.
