Method for limiting the speed of a motorcycle

A method for limiting the speed of a motorcycle, said motorcycle comprising a speed limiter able to operate, when a motorcycle speed-limiting mode is in an active state, to limit the speed of the motorcycle to at least a first speed limit Vlim, wherein:

• the speed limiter is switched from an inactive state to the active state if, and only if:
• the instantaneous speed of travel V of the motorcycle is above the speed limit Vlim and below said speed limit Vlim increased by a determined speed margin value Vth;
• and,
• an engine torque CMreq required by the rider of the motorcycle is below an engine torque CM that makes it possible to maintain the instantaneous speed of travel V of the motorcycle, increased by a first determined engine torque margin value CMth;
• and also
• the acceleration of the motorcycle is positive,
• such that the limiter, thus rendered active, commands the supply, to the motorcycle, of an engine torque equal in value to CM so as to maintain the instantaneous speed of travel V of the motorcycle,
• and wherein
• the speed limiter is switched from the active state to the inactive state if
• the engine torque required by the user is below the engine torque CM decreased by a second determined engine torque margin value Y, or if
• the engine torque required by the user is above the engine torque CM increased by the first engine torque margin value CMth,
• such that the engine torque required by the user is supplied to the motorcycle.
