Highest Top Speed Ever On A Busa

You can a get a much better answer to your question if you look in the Top Speed area of this web page. But here is a thread from the top speed area...this is the fastest Busa I've heard of...
Once you get to a certain speed there is only so much that hp can do for you. The aerodynamics of motorcycles are terrible, there was an interesting article in Cycle World about the Formula Extreme Hayabusa. They talk about overcoming aerodynamic drag and what not to try and be the first bike to top 200 mph in a race.
Personally I think 246mph on two wheels is impressive in itself. I don't know any $250,000 cars doing it... :rock:
