Dang Sproket, I think you are obsessed with wheelies? Cool. I spend a great deal of time on the back tire as well. I don't know how anyone can own a sport bike and not play on the back tire?
I noticed none of your wheelies are up very high and you sit way back on the seat? I have found if you want to balance on a wheelie, it's much easier to sit up tight against the tank. Do you find that as well?
Wheelies are fun. I just bought a Husaberg Supermoto, first one I've ever owned and that thing is a really fun bike to wheelie. Sooooooooo easy to bring up and carry a sustained wheelie until your forearms begin to ache.
Nice photos man!
