I've got an 00 R1 but have been contemplating if I should sell it and get an 06 Hayabusa. I don't know much about it or even driven it yet but I use to own a 95 Kawasaki ZX-11D, and it rode like a cadi with huge top end power. The reason for the switch is, my wife wants to ride with me (sometimes) and the R1 is just not as comfortable. After an hour trip we are both exhausted. I love my R1 but maybe I need more of a sport cruiser then a race bike. Let me know how you guys feel about the Hayabusa and any experience would definitely help me in purchasing or not.
