I've been wondering this. I don't stunt, so please forgive if the question sounds newbish...it is
So when you're doing a stoppie, are you supporting yourself with your arms on the clip-ons, or are you using your legs to clamp the tank like a mofo? The main reason I ask is becuz I see one-handed stoppies and wonder how the fark the bike still tracks straight with the rider trying to push it to the side.
