Axel Sliders are small devices that are attached to the outside edge of a motorcycle's front and rear axles. These are designed to prevent the axle from digging into the pavement in the event of a crash or low-side scrape and are mandatory in most forms of motorcycle racing on pavement.
Typically designed to bolt onto the axle, the axle sliders are easily removed or replaced with common hand tools in only a matter of a few minutes by a novice mechanic.
They are made of a rock-hard Delrin, nylon, or aluminum construction, the sliders keep the motorcycle raised slightly off of the road's surface in the event of a crash, thereby limiting the amount of damage that occurs to the chassis, engine, and body panels of the motorcycle.
Commonly used in riding, axle sliders are usually paired with frame sliders to allow the motorcycle to slide easily on the pavement without causing damage to the bike.
The small devices resemble skateboard wheels and can often be color-matched to the motorcycle, making them difficult to detect. When used in a road racing application, the axle sliders prevent the axles from digging into the racing surface when the motorcycle is leaned excessively into a turn.
This can prevent a crash from occurring and minimize both the damage to the track as well as to the bike
