I am looking at buying a 2001 RC51 and have a few questions. The bike has 10,500 miles and the engine runs strong with no strange noises, has two brothers exhaust, a power commander and now the worries I have. The seat has a gap at the back(said that the seat just needed to be recovered), scratches on the left side, just on the decals and while looking at the bike he had his son rip off some wheelies up and down the street so wondering about any other problems I should look for. He is asking $5000.00 and I am going to offer 4200.00 for the replacement of the decals, seat and needs new tires as he still has the original ones on it. Would like to get some opinions if it is worth getting or not. Thank you for your time.
