first thank God you are ok and had good riding gear.
A buddy that was riding behind me swears that I hit the kickstand earlier that day so that does sound reasonable.As mentioned in the other thread: Michelin pilot pure tires so not stock.
I can only speculate of course but since that was a left hander, I wouldn't be at all surprised if you levered off the kickstand after the peg folded back a bit. It looks like the rear just lets go.
The kickstand triangle hoop thing to make it easier to pull down sticks out darn close to the peg position when leaned all the way over. Once I get rearsets I'll probably need to grind mine off. Does it sound like a plausible theory?
I was just about to say, he is so luck with the trees. I have been down there quite a few times and usually people get really lucky.Not to be a party pooper but being an older (55) and still alive rider, first you're lucky you missed a tree since you wouldn't be here to talk about it, and second IMO a Grom is not anywhere near designed to be ridden they way you were especially on a PUBLIC road.
We've all done dumb things on two wheels and luckily you survived one. All I can say is I hope you've learned something from what happened. Hopefully.
