The invention discloses a motorcycle engine chain disc. The chain disc comprises a chain disc body, and a plurality of through hole sets are formed in the chain disc body; the multiple through hole sets are additionally formed in the chain disc body, in the working process, the chain disc body is driven by an engine to do high-speed rotation, and therefore a large amount of heat is generated by the chain disc body and the engine or the peripheral component; the temperature of the chain disc body rises, in the rotating process of the chain disc body, due to the arrangement of the through hole sets, the heat dissipating area of the chain disc body is increased firstly, and secondly, the driven air flow can penetrate the through hole sets in the rotating process of the chain disc body, so that the heat dissipating speed of the chain disc is increased; and the product stability is improved, and the service life of the product is prolonged.
