ATHENA Cylinder Base Gasket for HONDA CRF 50, CRF 70, XR 50 1988-2024

The ATHENA S410210006336 cylinder base gasket is designed for HONDA CRF 50, CRF 70, XR 50 from 1988 to 2024. The base gasket seals between the cylinder and the crankcase. Its thickness matters: it sets the height of the cylinder, and therefore the squish, the compression and, on a two-stroke, the port timing.

Key features

• Several thicknesses available for the same bike.
• The right tool for setting squish, compression and timing, according to Athena.
