So I just bought a 2005 CBR600rr and it goes to 255 f easily without really riding. What could be the issue? I’m new to bikes. Bought it from an independent dealer in the middle of no where Kentucky, it only has 5k miles so it should be 100% fine. It has a rebuilt title which I thought was a little suspect but the salesman said not to worry about it (of course). The rear brake is very stiff to press as well as the front break when ingaged is jerky. What should I do?
