[0002] A motorcycle chain is a key component in the motorcycle transmission system. It transmits the power of the engine to the rear wheel through gears, thereby driving the vehicle forward. The chain is designed compactly, has good power transmission efficiency and the ability to withstand high torque. It is mainly composed of a series of links, and these links are connected together by buckling or pins to form a continuous ring structure.

[0003] After retrieval, for the motorcycle chain pin and the motorcycle chain with the publication number CN204312621U, "including outer link plates, inner link plates, sleeves and pins, and the pins adopt the pins provided with mud discharge grooves as described above. In the utility model, mud discharge grooves are arranged on the pins. Once dust, dirt and other sundries adhere to the chain, after these sundries enter between the sleeves and pins inside the chain, they can be gradually discharged through the mud discharge grooves on the pins, effectively avoiding the jamming between the sleeves and pins and the blockage between the sleeves and the inner link plates on both sides, greatly reducing the friction between the sleeves and pins, and also greatly reducing the friction between the sleeves and the inner link plates on both sides, improving the service life of the sprocket; at the same time, lubricating oil can be injected into the mud discharge grooves to better lubricate between the sleeves and pins and between the sleeves and the inner link plates on both sides, making the whole chain run more flexibly and the transmission efficiency lower";

[0004] Based on the above patent, by providing a through mud discharge groove from one end to the other end of the pin, once dust, dirt and other sundries adhere to the chain, after these sundries enter between the sleeves and pins inside the chain, they can be gradually discharged through the mud discharge grooves on the pins, effectively avoiding the jamming between the sleeves and pins and the blockage between the sleeves and the inner link plates on both sides, greatly reducing the friction between the sleeves and pins, and also greatly reducing the friction between the sleeves and the inner link plates on both sides, improving the service life of the sprocket; at the same time, lubricating oil can be injected into the mud discharge grooves to better lubricate between the sleeves and pins and between the sleeves and the inner link plates on both sides, making the whole chain run more flexibly and the transmission efficiency lower. However, when this motorcycle chain is in use, mud discharge grooves are provided on the inner wall of the pin, increasing the friction between the pin and the link plate, resulting in accelerated wear between the link plate and the pin, shortening the service life of the chain, increasing the risk of chain breakage, threatening the safety of riders, and there is an unstable situation in the installation between the pin and the link plate, resulting in a risk of chain breakage, thus affecting the use effect of the motorcycle and the driving experience of the rider.
