Knee slider
Knee sliders are part of the equipment of motorcyclists. Although knee sliders can also be used by motorcyclists on public roads, they are mainly used in competitions.
Knee sliders are about the size of the palm of your hand and are usually made of plastic. They are attached to the side knee area of the leather suit with a Velcro fastener .
When cornering, such an incline can be achieved that the knee slider is pressed against the asphalt to control the incline. Usually this is achieved in connection with the cornering technique hang-off . If the slide is too strong , the knee slider can be pressed harder against the asphalt in order to take the load off the tires. In the best case scenario , this can prevent a fall, also known as a lowsider in the language of motorcyclists . Since the human sense of balance cannot correctly evaluate inclinations of 20 ° and less, knee grinding also serves to feel the inclination via the leg position.
By using different materials, you can change the feel of the sanding, the durability and the look. So offer z. B. knee sliders made of soft plastic have a very good ("smooth") abrasion behavior, wood can be used as a material for high durability. For a number of years there have been knee sliders with metal or ceramic inserts, which on the one hand give a soft sanding feel with a long shelf life (ceramic), on the other hand, with metal pins during knee grinding, flying sparks are generated, which sets the knee grinding in scene. The use of such knee sliders is sometimes prohibited on racetracks, as the flying sparks can irritate drivers behind.
When the knee slider comes into contact with the ground, a frictional force occurs which gradually decelerates the machine and the driver via the leg.
