The Tomahawk is one the wildest things ever to come out of Detroit and unfortunately it will never be produced for the simple reason that there would be a lot dead bodies lying around. Worse than the Tomahawk or any of the others is Jay Leno's Y2K. Still it one thing to have the numbers to go that fast and quite a different thing to actually do it.

No that I want to encourage you, but what is the fastest you have gone?
In a car over 160. I do know several people who have ridden these bikes flat out. They are crazy but they are out there. And yes they have made 160 on them numerous times.
Was this kid going 205? I doubt it. But there are bikes you can buy that will get you to 190 right out of the factory. With a little tweaking nitrous and exhaust . . . .
