A computerized system that senses wheel lock-up during braking and reduces the pressure applied to the calipers. Sensors monitor the rotational speed of the front and rear rotors
and, via a computer, compare the rotor speeds against the road speed. The computer instructs a control unit to reduce the brake pressure when the wheel is judged to be close to lock-up.
In the early days of ABS, a good/experienced rider could brake much later, and therefore harder, than the available ABS’. As the systems were further developed, along with their associated technologies, the systems became much more efficient. However, riders who have only ridden motorcycles with ABS must be extremely careful when riding a classic, for example, without these systems – particularly in wet conditions.
