I wish I had a mile or two of tarmac so I could top out all the bikes in my show room. Fastest I've ever been on a bike is 160 (No not that guys 9R, my 916) and I'm not sure if I'd want to test the top end of a ZX14 or Hayabusa we have here.
Ive been over 200 on my old turbo busa. Its honestly scary how fast your going at that point. I decided to sell it when I found myself hitting 180 too often. No need for that kind of power/speed on the street.
Thats why i bought my buell. It gets up to 130 quick enough. I would like ALITTLE more, but its more than enough for the street. I may eventually swap out for a chain drive setup to just get that little more I want out of it
