Vehicle speed sensor
Function To indicate the vehicle speed by reading the secondary transmission shaft rotation. Operating principle Hall-effect sensor: a square-wave pulse is generated with voltage between 0 and approximately 0.3-0.4V. Level in wiring diagram: Speed...

Engine revolution sensor
Function It informs crankshaft position and speed to the Marelli control unit. Operating principle Inductive sensor: sinusoidal-type generated voltage; two teeth are missing on the flywheel for the reference position. Level in wiring diagram:...

Throttle grip position sensor — removal
Function The throttle grip is the part to which the throttle control cables arrive; its task is to translate the rider's power request (Demand) into an electrical signal to be sent to the electronic control unit. Operating principle The two throttle...

Intake air pressure sensor
Function The pressure sensors (one per cylinder) are fundamental not only for the injection configuration at low and stabilised speeds, but also for checking the Ride by wire system: their signal is connected to a TORQUE CHAIN for checking the...

Engine temperature sensor
