on asphalt its a little shaky at 75ish. f*ck 120. a twitch on those bars and youre gonna die. street bikes are made for speed like that, the shee is not. well at least not if the only thing youve done is put a pipe on it. where youy gonna pull these speeds anyways? dont think a 1/4 mile is long enough, and theres no well in hell you coul get me to do it while not having trained medical supervision, IE medi-flight.
