Wössner Connecting Rod Kit for KAWASAKI KX 450, KX 450 X 2019-2023

WOSSNER offers this connecting rod kit for KAWASAKI KX 450, KX 450 X 2019-2023. 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 KAWASAKI KX 450?

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.
