| description | The invention provides a variable valve structure of an engine, and belongs to the technical field of motorcycles. The problem that in the prior art, a variable valve structure is insufficient in reliability is solved. The variable valve structure of the engine comprises a first air inlet rocker arm and a second air inlet rocker arm which are arranged on a rocker arm shaft, a first air inlet cam and a second air inlet cam are arranged on a cam shaft, the first air inlet rocker arm abuts against the peripheral face of the first air inlet cam in a matched mode and can drive an air inlet valve to be opened and closed, and a linkage pin parallel to the rocker arm shaft is arranged on the first air inlet rocker arm in a penetrating mode. The linkage pin is located on the side, close to the air inlet valve, of the rocker arm shaft and is higher than the rocker arm shaft, the second air inlet rocker arm abuts against the peripheral face of the second air inlet cam in a matched mode, and a pin hole parallel to the li |
