Method for warning a driver of a motorcycle , wherein the method comprises: monitoring traffic situations based on signals from at least one sensor ; upon detecting a critical traffic situation based on the signals from the at least one sensor , warning the driver by inducing an acceleration change onto the motorcycle ; wherein a current lean angle of the motorcycle is monitored and a manner and/or degree of inducing the acceleration change onto the motorcycle is set taking into account the current lean angle of the motorcycle , - wherein the acceleration change is induced by at least actuating a front wheel brake of the motorcycle in case the current lean angle is smaller than a predetermined first lean angle value, - wherein the acceleration change is induced exclusively by one or more of actuating a rear wheel brake of the motorcycle , reducing an acceleration torque generated by an engine of the motorcycle and temporarily shifting an automated transmission of the motorcycle to a lower gear in case the current lean angle is bigger than the predetermined first lean angle and smaller than a predetermined second lean angle value, the first lean angle value being smaller than the second lean angle value, - wherein no acceleration change is induced in case the current lean angle is bigger than the predetermined second lean angle. monitoring traffic situations based on signals from at least one sensor ; upon detecting a critical traffic situation based on the signals from the at least one sensor , warning the driver by inducing an acceleration change onto the motorcycle ; wherein a current lean angle of the motorcycle is monitored and a manner and/or degree of inducing the acceleration change onto the motorcycle is set taking into account the current lean angle of the motorcycle , - wherein the acceleration change is induced by at least actuating a front wheel brake of the motorcycle in case the current lean angle is smaller than a predetermined first lean angle value, - wherein the acceleration change is induced exclusively by one or more of actuating a rear wheel brake of the motorcycle , reducing an acceleration torque generated by an engine of the motorcycle and temporarily shifting an automated transmission of the motorcycle to a lower gear in case the current lean angle is bigger than the predetermined first lean angle and smaller than a predetermined second lean angle value, the first lean angle value being smaller than the second lean angle value, - wherein no acceleration change is induced in case the current lean angle is bigger than the predetermined second lean angle. - wherein the acceleration change is induced by at least actuating a front wheel brake of the motorcycle in case the current lean angle is smaller than a predetermined first lean angle value, - wherein the acceleration change is induced exclusively by one or more of actuating a rear wheel brake of the motorcycle , reducing an acceleration torque generated by an engine of the motorcycle and temporarily shifting an automated transmission of the motorcycle to a lower gear in case the current lean angle is bigger than the predetermined first lean angle and smaller than a predetermined second lean angle value, the first lean angle value being smaller than the second lean angle value, - wherein no acceleration change is induced in case the current lean angle is bigger than the predetermined second lean angle. <EOS>
