it wouldn't be a bad idea to wear a helmet while you're messing around like that - my second cousin was messing around in a field like that with his banshee, and when his front end came down from a wheelie his tie rod broke, he flew over the bars, and the quad flipped on top of him. broke his helmet into 3 pieces and broke his shoulder, but I don't think he would have walked away from it if he wasn't wearing a helmet. I don't want to sound like your mommy, but helmets are a good investment.
