A throttle valve control system for an internal combustion engine includes plural throttle bodies with respective intake passages formed therethrough. Each of the respective throttle bodies includes a throttle valve shaft and a throttle valve, the throttle valves are operated by an actuator via the throttle valve shafts. The throttle bodies are each provided with plural fuel injection valves, and fuel lines which connect adjacent fuel injection valves together are arrayed in parallel with a direction of the throttle valve shafts, and are arranged between the throttle bodies and the actuator.

An intake air control device is provided in which a valve shaft extends in the left and right direction of a vehicle body frame across an air intake path, and is rotatably supported by an air intake path forming body connected to an engine body, equalizing the distances from a center of the vehicle body frame in the left and right direction to both ends of the intake air control device when arranging the air intake path forming body at the center of the vehicle body frame in the left and right direction. An actuator, which applies a motive power to drive the valve shaft, is connected to one end of the valve shaft, and a throttle operating amount sensor for detecting the throttle operating amount by a vehicle operator is supported by the air intake path forming body and connected to the other end of the valve shaft.
