Glad you're ok and the bike can be fixed.
And congrats on the weight loss!
Loading mishaps are not uncommon. Don't feel bad.
I put mine through the back windshield of my truck a few year ago, have also spit ramps out (tie those babies off!) and dropped whole bikes going into the bed of a truck, and also have done exactly what you did by letting it go overcenter away from me. And also have failed to deploy the kickstand fully and had 'em fall over while walking away from it. (Did that one when the Max was only on it's 1st day of my home)
All of them are embarrasing, and I learned something everytime.
The worst was the window event when there were 30 of my friends with camera in hand :biglaugh:
The other one was a Yamaha UTV that had a complete ramp failure half way up the ramps when out in the desert, it came down on the back wheels and then went over backwards on top of me, I was out there by myself and damn lucky it didn't cripple me , I'da been coyote shit before anyone found me (It was an old one and did not have a rollbar)
Whats even more fun is camping out at busy boat ramps with a lawn chair and some beer, waiting for the trailers with paper tags to show up. No end to the fun in that, can anyone say "Schaudenfruede"??? :biglaugh: I'm not a complete asshole tho' I'll offer to help first.
