WISECO connecting rod kit for YAMAHA YZ 125, HONDA CR 80 R, CR 80 RB and KAWASAKI KX 125 K, KX 125 L from 1985 to 2014

WISECO offers this connecting rod kit for YAMAHA YZ 125, HONDA CR 80 R, CR 80 RB and KAWASAKI KX 125 K, KX 125 L from 1985 to 2014. 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 WISECO?

Wiseco crankshafts have a heat-treated, shot-peened rod and precision-machined flywheels, from the American engine specialist since 1941.

When should you replace the connecting rod?

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.
