To provide a motor cycle that suppresses a change in the rotation speed of an engine for driving a power generator.SOLUTION: A motor cycle comprises an engine, a power generator, a battery, an electric motor, a drive wheel, and a catalyst device. In the engine, catalyst warm-up operation is performed when the temperature of the catalyst device is less than a catalyst activation temperature, and high efficiency operation is performed when the temperature of the catalyst device is equal to or higher than the catalyst activation temperature. The catalyst warm-up operation and the high efficiency operation are different in a first intake cam 127c and a second intake cam 127d, which are provided in a valve gear 108 of the engine.SELECTED DRAWING: Figure 4 【課題】発電機駆動用エンジンの回転数変化を抑えた自動二輪車を提供する。【解決手段】自動二輪車は、エンジン、発電機、バッテリ、電動モーター、駆動輪、触媒装置を備え、エンジンでは、触媒装置の温度が触媒活性温度未満のときは触媒暖機運転が行われ、触媒装置の温度が触媒活性温度以上のときは高効率運転が行われ、触媒暖機運転と高効率運転とでは、エンジンの動弁機構１０８に備える第１吸気カム１２７ｃと第２吸気カム１２７ｄが異なる。【選択図】図４
