you could EASILY use it for a stunt bike. in fact that's what i was going to use it for, but i never did. put a cage and a 12 bar on it, and she's good to go. f2's/f3's make sick stunt bikes. the subframes are steel and handle ALOT more abuse than the aluminum subframes on most sport bikes.

i have ALOT of people interested in this bike, so if you're thinking of buying it, lemme know soon.
