The invention relates to a method for operating a control system (63) of a motorcycle (60), which moves an electromechanical steering lock (10) from an unlocked position (1) to a locked position (2) and vice-versa, with an ignition system (62) to start the engine of the motorcycle (60), which is controlled by the control system (63), an authentication (70), in which an ID-generator (64) maintains a data link with the control system (63), wherein after a positive authentication (70) in an operational step (71a,71b), the steering lock (10) is brought into the appropriate position (1,2). According to the invention, it is provided that the first actuator element (31) has a signal connection with the control system (63), which is accessible to the user, and the operational step (71a,71b) commences only after positive authentication (70) via intentional activation of the first actuator element (31), which occurs after the authentication (70).
