I am looking to buy my first bike. I was wondering what to look for as far as mechanically goes when buying a used bike. Is there any tricks or things I can do while test driving it to make sure it has not been abused? Aside from looking at the tire wear and checking for leaks I really dont know what else to do because I am not at all fimaliar with motorcycles. Any advice will help. Also, is there a cut off for high mileage cycles that a person should stay away from or does it depend on the year also?
