I'm considering getting a 2000 ZX-9R. The bike has 5k mi., looks in good condition and he is asking 6K. Is that a fair price? Should I get a newer bike (the 02 has a lot of improvements). I'm also thinking about the ZX-12R! Currently I have a ZRX-1100 which I really like and probably keep. I will sell the Roadstar (never ride it any more). The ZRX is really comfortable and my only concern with the ZX-9 or 12 is that I can't do 10h days any more. What are your ideas on this?
