ATHENA Top End Race Gasket Kit for 2-stroke engines, built for riders who refresh their top end before races or mid-season. Includes an MLSS head gasket and multiple base gaskets to dial in compression for pump or race fuel.
Prepare your 2-stroke engine for race day with the ATHENA Top End Race Gasket Kit—a purpose-built set designed for pro, semi-pro and amateur riders who want a reliable top-end refresh before a race or during the season. The key advantage is adjustability: with multiple base gasket thickness options, you can fine-tune your setup to match your fuel choice and desired compression.
This kit helps you optimize performance without guesswork. Run standard fuel with stock-like compression or step up to race fuel with higher compression by selecting the base gasket thickness that best suits your build. The included MLSS head gasket delivers excellent sealing performance under demanding conditions—ideal when pushing hard and maintaining consistent power.
Note: This kit does not include valve stem seals, rubber parts, shims, or other fiber gaskets.
