[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model provides an air inlet groove and a guide plate on the circular cover at the front end of the chain cover body corresponding to the engine, which is conducive to the entry of air during the running of the motorcycle. The middle part and the lower part of the rear end of the chain cover body are open. At the same time, a heat dissipation hole is provided at the front end of the chain cover body corresponding to the position of the engine, which is conducive to the discharge of the entered air. When the motorcycle is running, high-speed air passes through the circular cover and the chain cover body to achieve heat dissipation, effectively improving the heat dissipation efficiency of the motorcycle engine, and achieving the purpose of the motorcycle chain cover taking into account the safety protection, mud barrier and heat dissipation functions.

[0013] 2. The chain cover body, round cover, guide plate, connecting plate, reinforced angle plate, reinforced ridges and thickened ridges of the utility model are an injection-molded integrated structure with clean lines and simple structure. The cost and energy consumption of injection molding molds are reduced. At the same time, it is fully functional. The reinforced ridges, thickened ridges and reinforced angle plates can improve the overall structural strength, which is both beautiful and practical. BRIEF DESCRIPTION OF THE DRAWINGS
