I too was guilty of the "make a tight u-turn on a downslope" sin many years ago on my RT. What made it worse was that we were 2-up. It's amazing how results can be so predictable.Dropped my 2018 GTL 2 weeks ago trying to make a u-turn in a location I thought I could manage (Apparently not) Lost momentum half way thru turn and problem was I was perpendicular across a sloping road and went down heavy on the low side.
My next BMW was an LT that I dropped a few times believing the kick stand was down. It was the old adage that by the time you realize what's happening, it's too late. Those experiences have etched into my brain that I don't do u-turns on slopes, and to always stare down at my feet when I come to a stop. These techniques have served me well during my GTL ownership in that I've been able to keep the bike upright (knock on wood).
I'm sure there will probably be situations in the future that test the bike balancing gods. Given that I avoid riding in anything loose (sand/gravel) as much as possible, hopefully all will remain good. But I am tempted to get guards for the front and back. You just never know.
