When I rode my V Strom to Alaska from California in 2008 I dropped the darn thing 3 times on the trip. It was fully geared and heavy. The first 2 times it pretty much tipped while I was standing there and I caught it and saved it. The last time it was pouring down rain, and it happened just like yours. I started to do my weight transfer to get it up on the center stand and my boot slipped off. The bike went all the way over and was both wheels off the ground, laying completely on the gobi side box. There was no one around and I HAD to pick that mess up. Luckily I was 22 and excited by things like going to the gym and working out. So picking it up was tough but I got it done. Seven years and 80 pounds later I would probably have to walk home.
