The invention relates to a motorcycle with a push rod type engine. An engine of the motorcycle adopts the push rod type engine, and comprises a cylinder head, an air intake valve, an air exhaust valve, an air valve outer spring, a crankshaft connecting rod, a cam, compression ratio, primary transmission ratio, an air intake joint pipe, a carburetor and a rocking arm. An intake and exhaust system, an air distribution mechanism, a combustion structure, an ignition energy and power output mechanism, transmission ratio, a fuel supply system and the like of the traditional push rod type engine of a motorcycle are subjected to brand new optimization design, improvement and configuration structure readjustment. After being proofed by experiments, the push rod type engine of the motorcycle has the advantage that while the property of the engine is guaranteed, the fuel of the motorcycle is saved by more than 30%.
