Refresh your 2-stroke top end with an ATHENA gasket kit built for reliable sealing and race-ready performance. Multiple base gasket thicknesses let you fine-tune compression to match your fuel and setup.
Dial in your 2-stroke top-end rebuild with confidence. The ATHENA Top-End Gasket Kit is designed for riders who regularly freshen up their engine before a race or during the season and want dependable sealing with the ability to fine-tune performance. By including a premium MLSS head gasket and multiple base gaskets, this kit helps you set the compression ratio to suit your riding conditions and fuel choice.
Better setup flexibility, less guesswork: choose a standard, stock-style compression setup for pump fuel, or adjust compression higher when running race gas—while keeping sealing quality high where it matters most.
Note: This kit does not include valve stem seals, rubber parts, shims, or other fiber gaskets (as specified by the manufacturer).
