Athena Top End Gasket Kit for Honda (P400210600058)

The Athena Top End Gasket Kit, part number P400210600058, is designed for Honda riders who need a dependable engine refresh before competition or during the riding season. It is suitable for professional, semi-professional, and amateur applications, providing the essential gasket components required for servicing the top end of the engine with precision and confidence.
The kit includes a premium MLSS head gasket engineered to support reliable sealing under demanding operating conditions. It also includes two or more base gaskets in different thicknesses, allowing riders and technicians to adjust engine compression according to their preferred fuel and performance setup. Use the appropriate gasket combination for stock compression with standard pump gas, or select a higher-compression configuration for race fuel when supported by the engine build and tuning requirements.
Athena manufactures this kit to help simplify top-end maintenance while giving experienced builders greater flexibility during engine assembly. The included gasket options can assist with achieving the desired compression ratio without requiring a separate base gasket purchase. This makes the kit a practical choice for race preparation, midseason service, and performance-focused engine rebuilding.
This Athena kit does not include valve stem seals, rubber components, shims, or other fiber gaskets. Verify application compatibility with your Honda engine before installation, and follow the manufacturer’s service procedures for torque specifications, gasket placement, and final assembly. Choose the Athena P400210600058 Top End Gasket Kit for a focused, application-specific solution when refreshing the engine’s upper end.
