A straddle-type vehicle includes an engine, an air intake pipe, a throttle valve being controlled in accordance with an operation amount of an accelerator grip, an engine rotating speed detector or a vehicle speed detector, and an electronic control unit (ECU). The ECU increases the opening degree of the throttle valve or maintains the opening degree at a constant value until the engine rotating speed reaches a set rotating speed which is smaller than a prescribed rotating speed, but if the engine rotating speed exceeds the set rotating speed, the ECU reduces the opening degree of the throttle valve irrespective of operation of the accelerator grip.
