I purchased my ring about a year ago/March 2007 in anticipation of a 4000 mile trip on my K12GT, concerned that should I have had the failure, well, at least I wouldn't have to 'wait for parts'. BTW, trip came and went, no failure. At that time the dealer WAS NOT stocking
these rings as failures were only 2-3 (their words). Since then, I had the failure on my '07 ADV with about 1500 miles (the failure was in late January 2008 I believe, after a few minutes bike started). I took the bike in for service and the ring was replaced along with removing the security screws, for a quick and easy in the field fix, should one occur.
The main point of this reply is that BMW Daytona does indeed NOW STOCK THESE RINGS
! And, it appears from the posts that most dealerships are stocking these parts, which while not any definitive statistical data point, it does imply that failures are much more than a rare occasion.
BTW, I would feel comfortable doing another 4000 mile+ trip with a BMW, any model. At least from my [jaded/limited] perspective the bike(s) is/are unequivocally the finest available.
