A vehicle having a vehicle body, a seat, an engine, a throttle body, a throttle valve, a throttle valve actuator, a throttle operator, a throttle operator position sensor, a cruise control switch, and a vehicle speed sensor. An ECU controls operation of the engine in one of a normal operation mode and a cruise control operation mode. When in the normal operation mode, the ECU sends a first control signal to the throttle valve actuator based on the throttle operator position signal. When the cruise control switch engages the cruise control operation mode, the ECU sends a second control signal to the throttle valve actuator based on the vehicle speed signal such that the vehicle speed is maintained at a vehicle cruising speed. The ECU returns to the normal operation mode when the throttle operator position becomes less than or equal to a reference throttle operator position.
