The Bosch Antilock Braking System (ABS) for motorcycles assists the rider while braking in critical driving situations. The system prevents wheel lock-up and ensures bike stability as well as optimal deceleration while braking. ABS therefore significantly reduces the risk of falling and reduces stopping distance. Bosch, the pioneer of ABS development, has offered Antilock Braking Systems for motorcycles since 1994. Based on decades of experience, Bosch sets a new benchmark for motorcycle riding safety with the generation 9 of ABS for motorcycles.

Characteristics:

In the past, Antilock Braking Systems for motorcycles have typically been carried over from passenger cars, with little adaptation to motorcycle requirements. However, generation 9 of ABS base and ABS plus has been specifically designed to fulfil the motorcycle size and weight requirements. Compared to ABS generation 8, box volume and weight were reduced by half and the ABS software algorithm was modified to match the newly downsized hardware. The optimized control of the electric motor for the return pump results in enhanced brake lever feel and improved noise behaviour. ABS base and ABS plus fulfil strict requirements regarding vibration resistance as the magnet valve coils and the printed circuit board are mounted directly on the hydraulic unit.

ABS enhanced – Antilock Braking System with electronic Combined Brake System (eCBS) for motorcycles

In addition to ABS, attention is being placed on Combined Brake Systems (CBS), that link the brake circuits to best distribute the brake forces between the front and rear wheels. Combined Brake Systems are controlled mechanically or electronically. The mechanical type is not widely used as it requires specially designed brake components. In addition, the mechanical type is not able to cover certain braking conditions. In contrast, electronic Combined Brake Systems (eCBS) are using conventional master cylinders and calipers and are able to optimize the brake performance to the particular driving situation. For increased driving safety, especially on large and heavy motorcycles, Bosch has developed ABS enhanced which includes eCBS. With a weight of 1.6 kilograms and a volume of 1.2 litres, this Antilock Braking System is one of the smallest and lightest worldwide.

Characteristics:

ABS enhanced is available as a two-channel system for active pressure build up at the rear wheel, or as a three-channel system for active pressure build up at both wheels. For the eCBS function, additional valves and up to four pressure sensors are integrated into the ABS hydraulic unit. Therefore, the configuration of the ABS can be applied to the specific motorcycle characteristics.
