KTM EXC 250/300 24-26 Athena engine kit Connecting rod and gaskets

Athena Connecting rod and engine gasket kit for KTM EXC 250/300 24-26.

The Athena Connecting rod and engine gasket kit is a technical set developed for the complete engine rebuild of enduro and motocross motorcycles. This package from Athena brings together the essential mechanical components needed to work on both the top end and the crankcase in a single workshop operation, ensuring proper sealing and coordinated operation of the lower engine assembly.

The replacement of the Connecting rod and gaskets is recommended during the preventive maintenance intervals specified by the manufacturer, or when symptoms of wear appear, such as vertical play in the crankshaft, metallic noises in the crankcase, or loss of compression and fluids. Replacing these elements together prevents serious cylinder damage and ensures that no air leaks remain after closing the engine again.

This kit includes a forged Connecting rod manufactured in Japan, characterized by its strict dimensional tolerances and high structural strength under high-revving conditions. The gasket kit is made from materials with specifications equivalent to the original, avoiding the need to make modifications or adaptations to the original crankcases during assembly.
