Idle running of a drive wheel of a motorcycle is prevented without complicating the motorcycle structure. The motorcycle includes an engine, a drive wheel, a centrifugal clutch, a brake lever, a control unit for detecting actuation and de-actuation of the brake lever, a main stand that can be switched between a stored state where the rear wheel contacts a road surface and an upright state where the rear wheel is lifted off the road surface, and a main stand switch for detecting the upright and stored states. Engine operation inhibition control executed in the upright state permits operation of the engine when the brake lever is actuated and inhibits operation of the engine when the brake lever is not actuated.
