I've seen and have pics of an F658 with an early 09 build date where the rear wheel bearings were totally FUBAR and they came apart in many pieces when the wheel was removed.
The entire fuel system on the F bikes has had issues with the high ethanol fuels, there are posts on other forums about people being told by local dealers they'll need to run a chemical.
I have a feeling that with the new alternators and what appear to be a few other changes more than cosmetic, the newer F bikes will have far fewer teething problems. It is amazing to me that BMW would release a bike with the quantity of issues and "campaigns" as the original F models. They wouldn't think about marketing a car with these issues.
