i watched a programme bout a wheelie school and there method was 1st gear bout 20 mph then blip the throttle as if your coffing then off for a split second then wobble the throttle to maintain momentum.seemed to work for them.

also be careful as my mates just flipped his r1 doin a wheelie at 140mph.he was practicin for the straightliners wheelie comp thats on at elvington next weekend
