Well, it was the second — the first doesn’t count because (1) it was in my garage, and (2) it didn’t go all the way down (I was pinned between my bike and my wife’s C50).
Anyway, the actual on-the-road drop was at a stop sign, with cross traffic. I was turning right, and as I started off, I thought I was in first gear (I was in second). Just as I was tipping into the turn, the engine died. I put my foot down and tried to save it, but I ended up stepping off and easing the bike down. No damage, fortunately.
