It broke one very cold morning on the way to the Sunday session of the flight instructor refresher clinic, I heard a flap-flap-flap-flap, then silence, then the battery light came on. The bike took a trip home on the tow truck, and will get a new alternator belt this week. We've also learned our lesson about carrying a spare, we're each ordering an extra belt for our bikes for future use.
Poor thing just disintegrated, for all I know it's the original belt.
