The engine drag torque control monitors the rear wheel slip and specifically reduces the drag torque to keep the vehicle stable.
The MSR takes into account lean angle and slip angle (slip angle is calculated from the steering angle) to detect and reduce instability during braking at an early stage.
In order to be able to adjust the engine torque as finely as possible, the regulation – as in motorsport (WSBK / EWC) – takes place through cylinders 1 and 2.
