Athena Top End Gasket Kit for Honda (P400210600126)

The Athena P400210600126 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who want to refresh the engine before a race or during the riding season. Developed for dependable top-end service, this kit provides the essential gasket components needed to support proper sealing and consistent engine performance during installation or rebuild work.
The kit includes a premium MLSS head gasket along with two or more high-quality base gaskets in different thicknesses. This selection allows the installer to fine-tune the engine’s compression ratio according to the intended fuel and performance setup. Use the appropriate base gasket for a stock compression configuration with standard pump gas, or select a different thickness when preparing an engine for higher compression and race fuel.
Athena manufactures the P400210600126 kit for Honda applications with attention to fit, sealing reliability, and practical tuning flexibility. It is a useful choice for riders, technicians, and engine builders seeking a purpose-designed top-end gasket solution for maintenance, seasonal preparation, or race-focused engine work. Always verify application compatibility and follow the engine manufacturer’s service procedures during installation.
This kit does not include valve stem seals, rubber components, shims, or other fiber gaskets. Those items must be sourced separately if required for the specific engine service. The kit is supplied as a gasket-focused top-end solution and is intended to help simplify compression adjustment while supporting a clean, properly sealed engine assembly.
