A friend of mine just bought a 01 R1 and he thinks it's is a little to much for him. So he really likes my 01 ZX7R and wants to trade straight up. My bike has 4000 miles, Muzzy exhaust, new tires, eliminator kit and flush mount turn signals. The R1 has a 7500 miles, Micron high mount exhaust, eliminator kit and flush mount signals. Now for the bad, the R1 needs new tires and has a crack on the rear, near the brake light. What really scares me is that I don't know who owned the bike previously and how it was ridden and I know the R1 is a real popular bike among stunt/wheelie crowd, which makes me nervous because for all I know, some guy had it a beat the shit out of it. Please understand I am not stereotyping R1 riders as the R1 most likely will be my next bike(O5/06 model). I just don't want a bike that has a beat clutch,forks and gears. Thanks in advance for your opinions.
