i f*&cked up my thumb doin that. caught a tree with the right front tire and it just ripped the bars outta my grip. i spun the throttle control bout 90 degrees up on bars with my thumb. that sucked i had to use my palm to throttle back to camp.Man, that's pretty good. I bet that hurt...did you smash into the handle bars like I always tend to do when I hit inanimate objects at speed. I'm surprised that I haven't broken a hip like that!
