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.
A person that rides a motorcycle, particularly on a race track, that is able to turn in such a way, and at such a velocity, at such a low height, that their knee drags against the ground.
Casey Stoner, a professional MotoGP racer, is able to drag a knee through his turns. This is an example of a knee dragger.
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.
People who use telemark skis in which the heel is free from the binding as opposed to downhill skiing with which the heel is locked into the binding. Thus, these types of skiers have to drag there knee on the ground to make the tight turns which come so easily to the downhill skier.
