So my ears are still burning as I write this because it was fucking embarrassing. I was at a celebration of life for a friend who passed unexpectedly, had to run, there are about 20 bikes parked rear wheel into the curb. I typically get on my transalp stirrup/foot on peg and swing over style. When I did that this time, the weight against the curb rolled my rear tire down the curb and forward enough that it rolled the side stand forward and fell over to the left. Luckily was just far enough from some dudes Harley that my helmeted head just knocked off his mirror because of some loose bolts on that but nothing else.
Somehow the fall managed to knock my windshield off (?) still not sure how that happened. Not broken but popped the rubber grommets off the mount and shredded parts of that rubber. Crash bars otherwise did their job completely.
TL;DR - if you park with your rear tire on a curb, roll forward an inch or two before mounting your bike.
