I have just bought a 99 R1 off a mate who couldn't ride it anymore because he busted his ankle playing footy. The bike has been stored in his garage in Darwin for the past 2 years. I am not sure if they have been the same tyres the whole time, i will have to ask him. A friend of mine who is a more experienced rider said my tyres felt a bit hard or weird, they are Dunlop 208's. How long does it take for tyres to actually start to perish?
