The connecting rod links the piston to the crankshaft: this kit replaces it with its crank pin and bearing for a bottom-end rebuild.
WOSSNER offers this connecting rod kit for YAMAHA YZ 125, YZ 125 X from 2020 to 2027. The rod passes the piston’s motion to the crankshaft. Its big-end bearing spins at very high revs and eventually develops play.
Why replace the connecting rod?
The benefits:
- Remove the play that causes noise and vibration.
- Make a high-hours engine reliable again.
- Cheaper than a complete crankshaft when the flywheels are good.
Why choose WOSSNER?
Wössner has also forged its own connecting rods since 2010, with the same in-house forging expertise as its pistons.
When should you replace the connecting rod on your YAMAHA YZ 125?
Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.
The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
