This is a must see video documenting some crazy stunts by Travis Pastrana as he tests out some new stunt tricks from one of the biggest and most insane jump ramps ever made. The ramp started life at 14 feet tall. This wasn’t big enough so they jacked it up to 17 feet. This still wasn’t high enough so they increased this to 20 feet tall. From this monster ramp there are plenty of mental crash landings, bumps and bruises as they perfect the placement and size of the ramp and the landing zone. In the end a radar gun was used to record Travis’s speed on take off which recorded a spped of 50mph. Not for the faint hearted.
