At its heart, K-ACT ABS is an advanced anti-lock braking system, designed to keep tyres from locking up during braking. But K-ACT ABS was designed to be used on touring models weighing in excess of 300 kg – and that is before adding a tandem rider and luggage. Complementing its standard ABS function, K-ACT ABS links the front and rear brakes. It monitors the brake force the rider is exerting at both the front and rear, and takes into consideration vehicle speed to ensure highly effective braking while maintaining chassis stability. For example, let's say the rider pulls on the front brake lever. To keep the bike from pitching forward, the ABS ECU actuates the rear brake (via fluid pumps) to ensure that front-rear balance is maintained. Should the rider push the rear brake pedal, the system actuates the front brake as well to distribute the load more evenly so that the rear wheel does not lock up. Based on the vehicle speed, K-ACT decides the optimum hydraulic pressure to send to each caliper, ensuring that even with a heavy motorcycle, stable braking performance is possible.
