YAMAHA YZ 125 1974 - 1979 PROX CON ROD

ProX Connecting Rod Kit

The ProX Connecting Rod Kit is engineered to provide a high-performance, cost-effective replacement for your engine. Manufactured by leading Japanese OEM factories, these rod kits are designed to meet or exceed original equipment specifications, ensuring reliable operation and dimensional consistency for your motorcycle engine.

Every ProX connecting rod undergoes a double forging process on dedicated forgings. This specialized manufacturing technique enhances the grain flow of the metal, resulting in superior structural strength and long-term durability. To further improve longevity, the rods are shot-peened and barrelled to eliminate residual surface stress and create a smooth, refined surface finish.
