Wow 74/75 MPH honestly would scare the living crap out of me on my machine. Seems like when I am in the 67/68 range I personnaly start getting nervous. All I can think of is, "if I wipe out now I am history" and I start backing off. My buddy on the 450 R is another story, he is a fat bastid like me 250+ range and that machine still flys when he is on it, despite his weight! I aksed him if he ever gets scared when he is pulling away from me flying down the road, he said,"**** yeah I do, YOU'RE CRAZY!!!" LMAO Yeah sure... and he says I'm crazy.
