I'm looking to trade my bike for a 2001 ninja zx9. Was wondering if anyone has any experience with a kaw around this year (problems, thing breaking, etc.). The bike has just under 16000 miles on it and looks really nice. Just dont want to get a lemon. Any advice is appreiciated. The guy only wants $4000 for the bike or my bike and $500. Not sure if the price is right seems kinda low thats what concerns me.
