Dropped it, that's what I did to my GS today!
Was getting some tight corners in this morning on Mullholand Highway in the Santa Monica Mountains. The BMW tank bag worked its way loos at the steering head clamp (again). Pulled over (on a very slight down hill grade)to re secure it, put my hazards on, the side stand down, got off to attend to the bag and the Triple Black moved forward enough to fall over on its left side.
Lesson learned, put it in first and kill the engine, when on a down hill grade.
The AltRider engine guards did their job & took the fall and now have character.
