Holeshot, if you do a google search on BMW FD failure you'll get about a million hits. Use "final drive" instead of FD and you'll get more. A quick perusal will lead you to believe that all BMW motorcycles made in the last 20 years will have an FD failure, probably sooner rather than later.
If you actually spend time digging you might find that the previous design as found on the oilheads are more likely to have an issue, but hexhead FDs break, too. You also may find that BMW has made at least 3 different changes to the FD found on our hexhead bikes over the last 6 years in addition to some changes in maintenance procedures. Does that mean the "problem" has been fixed?
Alas, anything made can break. Only BMW knows the actual failure rate. Every time someone has a failure everyone else who has ever had a failure tends to find the thread and chime in. I believe that makes the actual failure rate look larger than it is in actuality, but perhaps that is wishful thinking on my part.
Yeah, there are sometime failures. Your's came early which follows the typical bathtub curve
of new part failure for just about anything manufactured.
Now let the flames begin!
