I remember those days of owning a crotch rocket. Uncomfortable, great gas mileage and extreme amounts of power. I had a 2005 Yamaha R1 with a filter, exhaust, lower gears and no emissions system on it. The gearing brought the top speed down from 180mph to 160. But that bike could get up to 150mph in 10 seconds no problem.
Even the stock bikes out perform every vehicle on the road:
I remember reading in a book that a motorcycle rider uses more neurons per second than a jet fighter pilot. The only difference is a jet fighter pilot doesn't have whales flying around with him.
