The invention provides a protection structure of a motorcycle crankcase fine filter, and belongs to the technical field of motorcycles. The problem that an existing motorcycle fine filter is prone to being impacted by stones is solved. The motorcycle comprises a frame and a suspension assembly, a crankcase is arranged at the bottom of the frame, the front end of the crankcase is connected with the frame through the suspension assembly, the suspension assembly comprises a connecting shaft hinged to the crankcase, the protection structure comprises a suspension arm, the top of the suspension arm is hinged to the frame, and the bottom of the suspension arm is hinged to the connecting shaft. The fine filter is fixedly connected to the side portion of the front end of the crankcase, located right behind the suspension arm in the front-back direction of the motorcycle and arranged in a retracting mode relative to the suspension arm in the left-right direction of the motorcycle. The protection structure of the motorcycle crankcase fine filter has the advantages that the probability that the fine filter is impacted by stones is reduced, and the service life of the fine filter is prolonged.
