The things you need to do to drag knee can help with speed and safety though. Look at knee down as a sign of proper riding form rather than an end unto itself. Step One : Get the right equipment. Not only are you going to be pushing the limits of your own performance capability - meaning you need to wear safety gear - but the articulation offered by a real riding suit makes all the difference in attaining the proper body position. Step Two : Find some good corners. Tracks have ambulances, corner workers to pick you up when you fall and instructors who can help translate this advice into reality.
