The automated shift assistant (ASA) is the logical and technical evolution of the tried-and-tested shift assistant Pro.
Electronically controlled actuators (stepper motors with sensors) operate both the clutch and the selector drum, thus enabling automated shifting actions. As a result, the comfort of shifting actions can be increased while maintaining the same high shifting dynamics.
In manual mode "M", the rider can change gear by operating the gearshift lever with their foot in the desired direction as usual:
- If the rotational speed of the target gear is within the maximum or minimum speed, the shifting action is carried out directly.
- If the rotational speed falls below a minimum limit, the system automatically downshifts, even in manual mode. This prevents the engine from stalling.
In automated mode "D", shifting actions are triggered automatically depending on the riding situation. The appropriate required gear is essentially selected depending on the engine speed, throttle grip actuation, lean angle and brake operation. The riding mode is used to adapt the gear selection to the drive characteristics. Even with automatic gear selection, the rider can request a gear change at any time using the gearshift lever without leaving "D" mode. The system automatically switches back to automatic gear selection as soon as a harmonious transition is possible.
The clutch operation for driving off and stopping is completely taken over by the ASA. The engine speed for pulling away is adjusted depending on the throttle grip actuation in order to drive off in a controlled way. When stopping, the clutch is opened before idle speed is reached.
