The vehicle body frame includes a pair of main frames extending rearward from a head pipe, and rear portions of the pair of main frames form a pair of body frames bent downward behind the cylinder head. The electronically controlled throttle includes a throttle valve provided in the intake passage and an actuator that opens and closes the throttle valve. In a side view, an upper edge of the actuator is along a lower edge of the suspension bracket, and a rear edge of the actuator is along front edges of the body frames.
