The MVICS (Motor & Vehicle Integrated Control System) platform integrated on the new F4 ensures precision control of multiple engine maps and rider assistance devices such as traction control and EAS (Electronically Assisted Shift). The central element is the Ride-By-Wire system: first seen on the three-cylinder F3 675, it has now been fully optimized and specifically redeveloped for the new F4.
Electronic redundancy ensures maximum effectiveness and safety: data from the two potentiometers is cross-checked with analogue signals, while a third sensor confirms the complete throttle closure requirement; two additional sensors are installed on the throttle bodies. Completely new – and developed specifically for F4 – is the inertial platform sensor set-up: this uses three gyroscopes and three accelerometers and provides the electronic control unit with an array of moment-by-moment info on vehicle dynamics. Consequently, traction control intervention is particularly accurate, thanks also to an encoder on the front wheel. This is a system that boosts both safety and performance, simplifying the entire riding experience, a key goal of the F4 project. The algorithms that define operation of the MVICS system continuously maximise the available torque at the rear wheel according to both road conditions and the rider’s own demands while electronically assisted gear shift, standard on all three versions, shortens gear changing times.
A further innovation is the Custom map, which lets you choose your own settings as an alternative to the default Normal, Sport and Rain options. This lets you customize five parameters (throttle sensitivity, torque, speed limiter, engine response and engine braking) so you can build up an engine control map that reflects your own individual riding style.
