I am not an experienced rider, two years ago I purchased an 1100 Honda Aero, I felt very insecure and uncomfortable on it. Friends tell me that the 650 Yamaha is the right bike for me because of my age and inexperience. I may be purchasing a 2001 custom/classic 650 tomorrow which has 8,000 miles. What are the weaknesses on this bike and can I expect a lot of problems because of the miles?
