Sounded like the rear end was sliding...I dont know that track at all, but did you just completely blow that corner or something? Hard to tell.
Sounded like you were off the gas and overloaded the front. Good thing, though, as crashes go it doesn't get much better...
What type of camera were you using? Looks like really good quality! Bonus points for the wheelie past mitch lol! PS...looks like the front let go rather than the rear imo...
