Athena Top End Gasket Kit for Honda (P400210600085)

The Athena P400210600085 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who want to refresh their engine before a race or during the riding season. This engine gasket set provides the essential top-end sealing components needed for reliable reassembly and consistent performance, making it a practical choice for maintenance, rebuilds, and compression adjustments on compatible Honda applications.
The kit includes a premium MLSS head gasket along with two or more base gaskets in different thicknesses. This selection allows riders and technicians to fine-tune the engine’s compression ratio according to their setup and fuel choice. Use the appropriate base gasket for a stock compression configuration and standard pump gas, or select a thinner option to support higher compression and race fuel applications when suitable for the engine build.

Proper installation, surface preparation, and adherence to the motorcycle manufacturer’s service specifications are recommended to help ensure long-lasting results.
