I've always had a BMW F650ST ever since turning 18. It never let me down so far, apart from one minor problem two years ago, when the carburetor was stuck and the bike was leaking fuel.
Yesterday, the starter motor apparently broke. Waiting for the replacement parts right now. Let's hope this is a one-time defect and not an indication that I should get rid of the bike before a long series of "bike is getting old" repairs.
