You probably saw the trailer for this one earlier this month and now the full video is online. With the help of Red Bull, Sebastian Keep built the biggest dirt quarter ever, measuring in at a scary 26 feet. Watch him, Ruben Alcantara and Ben Hennon get to grips with the beast. While you’re at it, have another watch of the great 10 minute documentary on Bas by our own Peter Adam here.
