ABSTRACT:
In an intake duct, a first intake passage arranged in a width direction of the front wheel and a second intake passage arranged on a side of the first intake passage are formed such that a flow area of the first intake passage is set larger than a flow area of the second intake passage. An intake control valve closes the first intake passage when the engine rotates at low speed and opens the first intake passage when the engine rotates at high speed.
