Top speed of a '99 Bandit? Don't know. Why don't you go find out, and then come back and tell us? My question is, if you do not know first hand what the top speed is now, why do you care what it wll be after the mods? I am not getting on your case, I just find it curious that somebody who hasn't tested the top speed of his bike stock cares what it will be after some mods, that's all. No offense.
