Editing Anti-lock braking system (section)

===CBS and ABS===
CBS helps to reduce the danger of wheel locks and fall downs but in certain situations, it is possible that CBS causes a fall down. If brake pressure is distributed from the rear wheel to the front wheel and the friction of the surfaces changes suddenly (puddle, ice on the street) the front wheel might lock even if only the rear brake has been applied. This would lead to a loss of stability and a fall down. CBS is therefore combined with ABS to avoid this on a motorcycle.
Different approaches are possible to realize this combination:
''Without active pressure Build up''
Single Version: A third additional channel links the rear wheel circuit through a delay valve to the front brake. Strong brake pressure at the rear wheel (or both wheels) pressurizes both brake circuits however this pressure is adjusted according to wheel speed and brake slip.

The dual version combines Hondas Dual CBS with a secondary master cylinder and a proportional control valve [with Piston ABS] A modulator regulates the pressure for each<ref name="honda5">{{cite web |url=http://world.honda.com/motorcycle-technology/brake/p5.html |title=Honda Worldwide &#124; Technology Close-up |website=World.honda.com |access-date=2013-02-12 |archive-url=https://web.archive.org/web/20131228002749/http://world.honda.com/motorcycle-technology/brake/p5.html |archive-date=2013-12-28 }}</ref>
''With Active Pressure Build up''
In 2009, Honda introduced the electronic controlled combined ABS for its high-performance sports bikes which utilize brake by wire technology. The brake input of the rider is measured by pressure sensors and the information is provided to an ECU. Together with the information of the wheel speed sensors, the ECU calculates the optimal distribution of pressure to prevent lockups and to provide the best possible deceleration. Based on this output a motor for each wheel operates a pump that builds up and regulates the brake pressure on the wheel. This system offers a fast reaction time because of the brake by wire functionality.

The MIB (Motorcycle integral Braking system) from Continental Teves and the eCBS (electronic CBS) in the enhanced Motorcycle ABS from Bosch are results of another approach. These systems are based on the pump and valve approach. Through additional valves, stronger pumps and a more powerful motor the system can actively build up pressure. The input pressure of the rider is measured with pressure sensors at the lever and pedal. The pump then builds up additional pressure adjusted to riding conditions. A partial integral System is designed for working in one direction only: front→rear or rear→front. A fully-integrated system works in both directions.

Because these systems are electronically controlled and are able to build up pressure actively, they offer the opportunity to adjust the motorcycle braking behavior to the rider. CBS and ABS can be switched off by experienced riders and also different regulation modes with higher and lower thresholds can be chosen, such as the rain or slick mode in the BMW S1000RR.
