ATHENA Race R4856-187 Engine Gasket Kit for Yamaha

The ATHENA Race Gasket Kit engine gasket kit is designed for those who want to maximize the performance of their racing engine.

Ideal for motocross and enduro applications, both 2-stroke and 4-stroke, this kit allows precise adjustment of key parameters such as cylinder height, squish, compression, and timing.

This kit is developed to provide a practical solution for engine tuning, enabling targeted adjustments thanks to the inclusion of cylinder base gaskets with different thicknesses.

This makes it possible to achieve the best balance between performance, reliability, and engine response, while maintaining the original technical specifications.

Each component is made from high-quality materials, selected to ensure resistance and durability even under extreme operating conditions.

The gaskets offer low moisture absorption, high mechanical strength, and perfect compatibility with oils, fuels, high temperatures, and pressures.

They are also designed to ensure optimal sealing without the need for silicone sealants, simplifying assembly and disassembly operations.

The result is a reliable, precise, and effective kit, designed to get the most out of the engine and achieve a perfect setup in any condition.
