press release

It is not always easy to bring a motorcycle to a halt. Especially when braking hard or riding on a slippery surface, there is a risk that the wheels will lock and the biker will take a spill. The Bosch ABS antilock braking system enables motorcyclists to brake much more safely because it prevents the wheels from locking. As well as preventing falls, this also considerably reduces braking distance.

Benefit: The enormous increase in safety that this system achieves is confirmed by a Bosch study based on the German accident database GIDAS: fitting ABS as standard would prevent one-quarter of all motorcycle accidents. The antilock braking system would also have a positive influence on a further one-third of accidents.

A mandatory ABS for motorcycles can save more than 5,000 lives by the year 2020, according to a benefit analysis conducted for the European Commission. ABS promises a significant improvement in road safety for emerging economies in Asia and South America, too.

Function: In a motorcycle fitted with an antilock braking system, the ABS control unit constantly monitors the speed of the wheels using wheel-speed sensors. If a wheel is about to lock, the system regulates the braking pressure in such a way as to allow the biker to brake safely. This means the motorcycle remains stable and under control – even when sand, gravel, or wet conditions make the road treacherous – and significantly reduces the risk of falling as a result of braking.

Modular kit: The Bosch Generation 9 ABS for motorcycles is the first antilock braking system to have been developed especially for motorcycles. At a volume of 0.5 liters and weighing 700 grams, it is much smaller and lighter than previous systems that were based on car systems. Thanks to its modular design and various degrees of functionality, this technology can be applied in every performance class – from low-cost entry-level motorcycles to supersport models.

ABS 9M light is the entry-level antilock braking system. Since it works solely on the front wheel, this 1-channel system is less expensive than conventional 2-channel ABS. It was conceived for low-cost motorcycles in the emerging economies of Asia and South America. This system can be applied only to motorcycles fitted with a hydraulic braking system – a feature that is fast becoming a standard across all markets. The start of series production is scheduled for the beginning of 2014.

ABS 9M base offers full antilock braking protection for both front and rear wheel. The system reacts reliably even when road conditions suddenly change, such as with gravel or oil spills.

ABS 9M plus is suited to more powerful motorcycles. The ABS control unit’s performance is further improved by an additional pressure sensor, which enables the system to recognize an imminent rollover even earlier and take steps to prevent it.

The highest-performance version, ABS 9M enhanced, also offers the eCBS function, which stands for “electronically combined brake system.” This novel combination of front and rear brake means that the biker need only apply one of them – either front or rear – for ABS 9M enhanced to automatically apply the other as well, without increasing the force the biker must apply or altering the brake force. ABS 9M enhanced is able to help moderately stabilize the motorcycle’s banking angle and its tendency to return to an upright position whenever the biker brakes while leaning into a bend.

Motorcycle stability control: This safety system is based on ABS 9M enhanced and has been expanded to include an extensive array of sensors and sophisticated software. This makes it the world’s first system to offer support in all riding situations: during both braking and accelerating, and while riding straight as well as while cornering.

Additional functions for even more comfort and safety
Not only can Bosch ABS improve the motorcycle’s braking effectiveness, it also offers a range of additional functions that improve motorcycling safety and comfort even further.

Traction control: This can prevent the rear wheel from spinning during acceleration, and counteract front-wheel lift. Traction control can be integrated into all 2-channel systems of the Bosch Generation 9M ABS.

Hill hold control: Until now, to avoid rolling backwards while standing on an incline it was necessary to apply the brakes continuously. Hill hold control maintains the braking pressure after the biker has released the brakes. This keeps the motorcycle still until the biker moves off again. This comfort function can be integrated into ABS 9M enhanced.

Safety on two wheels since 1994
Bosch has been manufacturing antilock braking systems for motorcycles since 1994. Their first application was in a Suzuki motorcycle for the Japanese police force. Since 2007, development work on these systems has been done at the Bosch center of competence for powered two-wheeler safety in Japan.

Mandatory ABS: The European Parliament has mandated ABS from 2017 for all motorcycles with more than 125 cc displacement. This directive applies from 2016 to any new models that are launched. Smaller motorcycles with a displacement of 50 cc or more must be fitted either with ABS or a combined braking system. However, the latter merely establishes a mechanical connection between the front and rear brakes and ensures that both wheels slow down whenever the brakes are applied. It does not prevent the wheels from blocking, since it lacks the control of braking pressure that is a feature of ABS.

Mobility Solutions is the largest Bosch Group business sector. In 2015, its sales came to 41.7 billion euros, or 59 percent of total group sales. This makes the Bosch Group one of the leading automotive suppliers. The Mobility Solutions business sector combines the group’s expertise in three mobility domains – automation, electrification, and connectivity – and offers its customers integrated mobility solutions. Its main areas of activity are injection technology and powertrain peripherals for internal-combustion engines, diverse solutions for powertrain electrification, vehicle safety systems, driver-assistance and automated functions, technology for user-friendly infotainment as well as vehicle-to-vehicle and vehicle-to-infrastructure communication, repair-shop concepts, and technology and services for the automotive aftermarket. Bosch is synonymous with important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology.

The Bosch Group is a leading global supplier of technology and services. It employs roughly 375,000 associates worldwide (as of December 31, 2015). The company generated sales of 70.6 billion euros in 2015. Its operations are divided into four business sectors: Mobility Solutions, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 440 subsidiaries and regional companies in some 60 countries. Including sales and service partners, Bosch’s global manufacturing and sales network covers some 150 countries. The basis for the company’s future growth is its innovative strength.
