YBR125 motorcycle connecting rod assembly, center distance 89MM, large and small hole/pin size strict standard YBR125 crankshaft + piston, directly replace the original connecting rod without changing the assembly gas mechanism; The connecting rod body adopts forged alloy steel, the strength is 3 times that of ordinary cast iron, which is suitable for high speed and high load of engine. Copper bushing (reduce wear buffer) + needle roller bearing (reduce friction resistance), one-stop solution to the wear problem of connecting rod components; Before leaving the factory by professional dynamic balance detection, running vibration is small, reduce engine abnormal sound and cylinder wear; Precise hole tolerance design ensures the power transfer efficiency of piston and crankshaft and improves engine output performance.
