Riding wheelies on flat ground or on a road is not nearly as hard as on hills or a track. Shoot, I've seen little girls ride wheelies on the road. I saw Doug Domocos (sp) ride one all the way around a supercross track and then across a high wire on an 3wheeler. He had to be the king of wheelies!! Any time you have to tilt the carb on a bike to keep it running while wheeling your good!!
