  Complete Gasket Kit (oil seals included).

  Athenas Complete Engine Gasket Kits for off-road applications are engineered to meet the toughest demands of motocross, enduro, and ATV / UTV engines. Designed for full engine overhauls, this kit provides every seal and gasket needed to restore performance and reliability under the harshest conditions.

  Every seal you need, in one complete kit.

  This Athena Engine Kit includes all essential gaskets and seals: head, base, crankcase, exhaust, valve cover, engine oil seals, valve stem seals, O-rings, and washers. Nothing is left out - each component is selected to ensure long-lasting performance in high-stress environments.

  Race-developed technology for offroad performance.

  Athena supports top teams in MXGP, AMA Supercross, Pro Motocross, and EnduroGP. Gaskets are tested on track and refined through direct collaboration between Athenas R&D department and race engineers. The same technology used in competition is made available to all riders.

  Trusted by O.E.M.s worldwide.

  Athena has long-standing partnerships with leading European and Japanese off-road manufacturers. This ensures perfect O.E.M. compatibility, precise fitment, and consistent performance across a wide range of off-road engines.

  Advanced design and total quality control.

  Each gasket is developed using 2D / 3D modeling, Fuji Paper and Tin Testing, FEM simulations, and validated on static and dynamic test benches. Multi-layer embossing ensures uniform compression and optimal sealing. Dimensional accuracy is verified using profilometers and Virtek systems.
