Not sure. In Kranked 3 he is on a old version of the RM9, Ride to the Hills a GT, not sure what he is riding in SHift though I think he was a Rocky DH racer at that time, need to re-watch that tape. I do remember Jesse Roberts riding one in Ride to the Hills with a Boxxer and 24in rear. Thats the set up I would like to give it. Love that movie. Needs to come out on DVD!
