The heart of the ABS system installed on the F4 supersport model is the compact, lightweight Bosch 9MPlus control unit. The unit contains pressure sensors that interface with the two phonic wheels, one per wheel.
The system’s main objective is to reduce the braking distance on wet or otherwise low-traction surfaces.
In addition to preventing the locking of the wheels, the ABS also reportedly prevents the relative deceleration from causing the rear wheel to lose contact with the asphalt, thus impeding the motorcycle from tipping forward. This situation, which according to MV Agusta is not uncommon on sportbikes with powerful brakes, is prevented by the Bosch 9MPlus control unit, which implements the appropriate countermeasures whenever the rear wheel loses contact with the asphalt.
The ABS offers two operating modes selected via handlebar controls: Normal mode, which ensures the system’s effective intervention at all times, above all when on the road, and Race mode, which limits the system’s intervention to the minimum. The latter is “ideal for use on the track and on roadways that allow for a more extreme approach,” according to MV Agusta.
The rider can also disengage the ABS entirely.
