I'm looking at a 2009 F 650 GS twin for my wife. It has 15K miles and they are asking $8,700. She has ridden one and likes it. # 1. Is this to many miles for the price? It has many accessories such as bags and stuff and new tires. #2. What should I look for as far as problem areas? #3. How many miles should I expect this motor to last? And are there any issues known to occur with time? Thanks and any advice would be appreciated.
