Athena Top-End Gasket Kit for 4-stroke engines, built for riders refreshing the engine before races or mid-season. Includes a premium MLSS head gasket plus multiple base gaskets in different thicknesses to fine-tune compression.
Refresh your 4-stroke top end with confidence using the Athena Top-End Gasket Kit—engineered for riders who service their engines before a race or as part of a mid-season rebuild. The kit features a premium MLSS head gasket and two or more base gaskets in different thicknesses, giving you practical flexibility to dial in the compression ratio for your exact setup.
By providing multiple base gasket options, this kit helps you choose between a more standard, stock-style compression for pump fuel, or a higher-compression configuration better suited to race fuel—making it easier to match performance and reliability to your riding conditions.
Note: This kit does not include valve stem seals, rubber parts, shims, or other fiber gaskets.
