Setup, Compatibility & Care
Compatibility: This connecting rod is exclusively designed for Yamaha YZ125 models manufactured between 2022 and 2025. Always verify your motorcycle's specific model year before purchase.
Setup:
- Disassemble the engine to access the crankshaft.
- Carefully remove the old connecting rod assembly.
- Clean the crankshaft and crankcase mating surfaces thoroughly.
- Install the new ProX connecting rod components (crankpin, bearings, washers) following the manufacturer's service manual.
- Crucially, use a calibrated torque wrench to tighten the crankpin nut or bolts to the exact specifications outlined in the Yamaha service manual. Overtightening or undertightening can cause severe engine damage.
Care: While the connecting rod itself is a sealed component within the engine, proper care involves maintaining the engine's lubrication system. Ensure you use the correct oil-to-fuel mixture and change engine oil regularly according to the service manual to prolong the life of all engine components, including the connecting rod bearings.
