Great video, did anyone notice that he did it with mini-apes? Watched it several times and still not remember how many times I heard the floorboards scraping, except the big one at the end. Yeah Clint, he was feathering the clutch and blipping the throttle (it is harder to control abrupt throttle response than smooth power using friction zone clutching. He used the back brake a lot, even level the suspension as several times the front end wanted to wash out while he was pitching the bike violently side to side while changing directions.
