be carefull on them and USE A HELMET! i was at an ATV park riding my new quads about a year and a half ago and i rolled it going about 20 MPH and i dont want to think of what would have happened if i didnt have a helmet. i hit my head on the ground so hard, i had a head ach for 5 days. i also broke my tailbone and if it kept rolling, it would have snapped my leg because it got caught between the tire and the frame. i know they arnt the same vehicle but the dangers are just the same.
