actually... hes hitting the rear brake... hitting the rear brake in the air makes your bike dip foward (think about it: the wheel is spinning at like 10,000 rpm when you hit the ramp... as soon as you leave, you nail the brake and make that wheel stop, wheres the momentum going? up [rear wheel]) and no the bike doesnt die.. as long as you pull the clutch in at the same time, your engine speed will stay up even though the wheel isnt working... and yes, it looks like hes on a 100 and just barely getting it around into foam... it will be another year before we see one on dirt with a 125..
