I have been on motorcycles since I was 6. I used to ride a Yamaha FZ1 which I could wheelie a mile on. Me and that bike hit a guard rail at about 80mph. Now I ride a gsxr750, and while I can still wheelie forever on my dirt bike, I don't even wheelie on my 750, she's too pretty to hit the ground. It's all fun till you hit the pavement. You're much safer with both wheels on the ground.
