http://www.sportrider.com/bmw-now-offers-abs-pro-retrofit-to-older-s-1000-rr-models Technically speaking, ABS Pro adapts ABS control to the motorcycle’s banking angle depending on the current situation on the road. In order to determine the bike’s banking angle, the system draws on the signals for roll rate, yaw rate and transverse acceleration as provided by the sensor cluster – which are already used for Dynamic Traction Control DTC and for the electronic suspension DDC Dynamic Damping Control. As the banking angle increases, the brake pressure gradient is limited more and more at the start of the brake maneuver. This means that the pressure build-up is slower. In addition to this, pressure modulation within the ABS control range is more even. The benefits of ABS Pro to the rider are a sensitive response and a high level of brake and ride stability together with the best possible deceleration on bends. The influence exerted by ABS control will depend on the riding mode configured. ABS Pro is available to its full extent in the modes “Rain” and “Sport.” During the pre-ride check, the display “ABS Pro” in the instrument panel in conjunction with the modes “Rain” and “Sport” indicates to the rider that the ABS Pro function is available. By contrast, the “Race” and “Slick” modes for very sporty, experienced riders do not support the ABS Pro function since it is deliberately designed to be used on roads.
in theory that would make trail braking on track a whole lot easier (obviously depending how good the system actually is),but from reading that,it is used in race mode not slick,which is pants on track.
