Vehicle speed limiter

A vehicle comprising:

• a vehicle body;
• a straddle seat for a driver, the seat being associated with the vehicle body;
• a handlebar for steering the vehicle disposed forwardly of the straddle seat;
• an engine associated with the vehicle body for powering the vehicle, the engine having at least one combustion chamber;
• an electronic control unit (ECU) on the vehicle for controlling an operation of the engine;
• a throttle body in fluid communication with the at least one combustion chamber;
• a throttle valve disposed in the throttle body for controlling an amount of air supplied to the at least one combustion chamber;
• a throttle valve actuator operatively connected to the throttle valve and in electronic communication with the ECU;
• a throttle operator mounted on the handlebar;
• a throttle operator position sensor for sensing a throttle operator position and in electronic communication with the ECU for sending a signal representative of a throttle operator position to the ECU;
• and
• a vehicle speed sensor for sensing a vehicle speed and in electronic communication with the ECU for sending a signal representative of a vehicle speed to the ECU,
• the ECU sending a control signal to the throttle valve actuator based on the throttle operator position signal and the vehicle speed signal,
• the throttle valve actuator adjusting a degree of opening of the throttle valve in response to the control signal,
• if the vehicle speed is lower than a predetermined maximum vehicle speed, the control signal causing the throttle valve actuator to adjust the degree of opening of the throttle valve based on the throttle operator position signal, and
• if the vehicle speed is higher than the predetermined maximum vehicle speed, the control signal causing the throttle valve actuator to reduce the degree of opening of the throttle valve.
