A safety system for a motor bike includes an evaluation and control unit which receives crash-relevant information from at least one sensor unit and evaluates it for the purpose of detecting a crash, and in response to a detected crash, the evaluation and control unit activates at least one external safety component and/or at least one internal safety component using a triggering concept. The evaluation and control unit receives presence signals from the at least one external safety component and/or the at least one internal safety component and evaluates the received signals in order to detect the safety components currently available. The evaluation and control unit selects the triggering concept as a function of the detected safety components currently available.
