Motocross has seen a rise in the number of racers who "scrub" their speed, or whip the motorcycle to the side. They claim that whipping the bike sideways off the jump lowers the hangtime so they can get back down to accelerate, therfore having a faster lap time. It is also claimed that sliding the bike off the jump helps make a faster lap by not jumping as high. here is a video of a scrub http://www.youtube.com/watch?v=4IMZZXLXPTU&feature=related The scrub just does not look as aerodynamic as jumping in a straight line. I would think that the whip would add more wind resistance therfore loosing more foreward momentum than jumping straight. I also would think that sliding up the jump loosing traction would slow the rider down. I do beleive it does get them back on the ground faster because of loss of momentum, but I dont see how this would make them any faster compared with going straight. I actually think the opposite. I know the rider would have a longer hangtime by jumping straight, but I dont think the rider would loose as much momentum. I would like to do a controlled study on this one day, but for now this is my theory. What do you guys think?
