YBR125 motorcycle drive chain, 428H model + 118L length, and YBR125 drive size tooth exactly match, directly replace the original chain without cutting; The chain joints are made of thick hardened steel, with high tensile strength and abrasion resistance of tooth surface. They are suitable for high frequency meshing transmission conditions to extend the service life of the chain. Built-in high hardness roller, small friction resistance when meshing, no transmission lag, no abnormal sound, to ensure the efficiency of power transmission; The surface is blackened and rust-proof, suitable for rainy days, wet environment riding, reduce the chain corrosion caused by transmission lag; After aligning the size and size of the tooth meshing, connect the live joint (need supporting tools), adjust the tightness can be used, the operation is simple and efficient.
