PROX connecting rod kit for SHERCO SE-R 125 from 2018 to 2021

PROX offers this connecting rod kit for SHERCO SE-R 125 from 2018 to 2021. 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 PROX?

ProX connecting rods are double-forged Japanese steel, heat-treated and shot-peened, made in Japan with the same shape and dimensions as the original part.

When should you replace the connecting rod on your SHERCO SE-R 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.
