I had one for 3 years and 46kmi. I ran it at tracks all over the midwest, yet put 900 miles on it in a single day between Indianapolis and Salt Lake City. At 6'4" there aren't many choices out there for guys my height. While a ZX 14 may be quicker, it's the same argument between a BMW M3 and a Corvette. Sure a Vette produces great numbers, but it will never equal an M3 or 911. It can't at less than half the price! If you like numbers, buy a Kawi. They are tremendous values for the money. Same with the Concours vs a K1300GT. If you have the difference in purchase price you'll never regret owning one.
Sooooo...I've not been looking at/researching/riding bikes for a few years...is this the new Hayabusa? Are they basically the same class intended to meet the same "needs"?
