Term used to describe the act of motorcycle roadracing, in which the rider's inside knee often comes in contact with the track surface while cornering and with the motorcycle leaned over. Knee dragging is more likely when the rider is hanging off of the motorcycle - a technique used to minimize the lean angle of the machine and thereby maximize tire traction. For this purpose, leather roadracing suits incorporate knee pucks (also known as knee sliders) on the outside of each leg, just below the knee.
Taking a corner on a fast motorcycle, with the bike leaned over so far you have to drag your knee to maintain balance. Knee pads with plastic or even metal pucks are made for this purpose.
