well the thing about the 500 is that, well you always have way too much power at your finger tips. i love it but alot of my friends, alot of people bigger than me dont like it. they think its too much. i weigh in at 175-185 and my friends who are 240-260 drive 250 2 strokes.
i know it sounds funny but your 500 will accelorate just like your street bike. only thing is the 500 will top out at 80 and your street bike will top out at 180
