ATHENA P400485600187 gasket kit for Yamaha

The ATHENA off-road emery series engine gasket kit is designed to deliver high performance and maximum reliability in the overhaul of the engine’s top end.

Ideal for motocross, enduro, and ATV/UTV applications, this kit ensures precision and durability on demanding terrains such as mud, sand, and dust.

Developed from direct experience in top-level competitions such as MXGP, AMA Supercross, Pro Motocross, and EnduroGP, this kit is based on technologies created on the track and tested by professional riders.

The solutions adopted come from continuous research and development, directly transferring racing-level quality to the final product.

Each kit includes all the necessary gaskets for the overhaul of the engine’s top end, such as head gasket, cylinder base gasket, exhaust gasket, O-rings, and washers.

The selected materials ensure resistance to high mechanical and thermal stress, maintaining a reliable seal even after prolonged use.

Advanced design using 2D/3D modeling, specific tests such as Fuji Paper and Tin Test, FEM simulations, and verification on static and dynamic test benches ensure total quality control.

The multi-layer embossing is designed to provide uniform compression and optimal sealing in all conditions.
