In a motorcycle fitted with an antilock braking system (ABS), the ABS control unit constantly monitors the speed of the wheels, using wheel speed sensors to register the rotational speed. If a wheel risks locking due to intense braking or slippery road conditions, the ABS hydraulic unit reduces the braking pressure applied by the rider and controls the wheel speed as well as the vehicle deceleration. This preserves the gyrostatic effect of the wheel and keeps the bike stable even on varying surfaces such as sand, loose chippings or water, thus shortening the braking distance and significantly reducing the risk of a brake-induced fall. Multi-level ABS allows a certain degree of tolerance before stepping in to assist with braking duty. For instance, the KTM Adventure models have an ‘Off-road’ mode that is better suited to gravel and loose soil.
