+1 for look where you want to go. At RTI they had setup 2 90 degree turns. When I looked at the exit of the turns my bike went straight through. I was afraid to lean the bike and turn the front wheel.
When I looked at the entry of the 2nd turn, suddenly the bike was there, then I look at the exit of the turn and boom, bike was through both turns no problem.
What that guy is doing in the video is a little more advanced, to say the least, however practice on a bike you aren't afraid to drop and wear the right equipment, in case it happens, and you'll be a pro in no time!
