ATHENA Complete Gasket Kit - Yamaha P400485850263

When rebuilding or refreshing your engine, gasket failure isn't an option—it compromises compression, causes leaks, and sidelines your bike. The ATHENA Complete Gasket Kit delivers OEM-quality sealing across your entire top-end with materials engineered for sustained high-temperature performance and reliability. This is a comprehensive solution that eliminates the guesswork of sourcing individual gaskets and seals.

ATHENA's proven construction combines rubber-coated steel bases with high-springback core materials that maintain clamping force through thermal cycling. The transparent high-temperature coating and blue silicone beading on critical flat gaskets ensure consistent sealing even under extreme operating conditions.
