Honda testing ABS brakes on CBR600RR



Many motorcycles in today's market feature anti-lock brakes, including models from Honda like the Interceptor and Silverwing scooters. Now, though, the red-winged manufacturer of motorcycles has announced a new system which completely removes the rider's direct connection with the front and rear brakes. Instead of a cable connection, the system uses brake-by-wire technology and allows an on-board computer to apply pressure to both the front and rear brakes as it sees fit. This new system is expected to debut on sportbikes first, which raises some eyebrows in the cycle-riding community. The highest performing bikes have ridiculously powerful brakes which are capable of locking up the front tire very easily. Still, hardcore riders have proven very reluctant to give up any control to computers, especially on race tracks, where supersport bikes are expected to thrive. Being Honda, though, there is a prevailing sense that the technology will work. Expect the new combined ABS system to proliferate to all of Honda's two-wheelers in the near future.

Honda Announces World's First Electronically-Controlled 'Combined ABS' for Super Sport Bikes

Honda has announced the world's first electronically-controlled "Combined ABS" for Super Sport motorcycles, aimed at combining ABS and CBS systems into one system that applies the basic advantages of both, while specifically addressing the requirements of a Super Sport context.

In order to achieve this, the particular characteristics of Super Sport bikes, such as short wheelbase, are taken into account. The system also operates without interference to sports riding, and with an emphasis on maintaining full rider control.

The system consists of an electronically controlled combined "brake by wire" system with an innovative stroke simulator. Direct motor control ensures precise operation of the ABS. The components are divided into several smaller units so there are more, but smaller units than in previous systems.

The system's effectiveness is due to four main factors:

1. Electronic control of the CBS, allowing more advanced control of brake force. This provides a more sensitive distribution of brake force over both wheels.

2. Measurement of rider input force on each lever. The ideal brake force on both wheels is generated accordingly, providing optimum distribution and minimising vehicle body reaction.

3. An "ABS modulator" which ensures late triggering of ABS, and smooth ABS intervention.

4. Small size meaning that the system's components can be well integrated in the motorcycle's package. Thus mass-centralisation, a key feature for Super Sport bikes, is supported.

All the basic ABS and CBS functions are provided, including the prevention of wheel lock, improved balance and easy operation. This is achieved without any compromise to stability during ABS operation. Pitching is minimised so that the bike keeps its normal position. Overall, sport riding performance is uninterrupted - cornering feel remains the same and controllability is enhanced.
