Top-End Gasket Kit

Refresh your 4-stroke top end with confidence. The ATHENA Top-End Gasket Kit is designed for pro, semi-pro and amateur riders who service their engine before a race or during the season. With a top-quality MLSS head gasket and multiple base gaskets, you can rebuild reliably and fine-tune compression to match your fuel choice and performance goals.

This kit helps you dial in the engine setup: keep stock-style compression for pump fuel, or increase compression when running race gas—without guessing, thanks to the included base gaskets in different thicknesses.

Key features:

• ✅ Premium MLSS head gasket for strong sealing and durability
• ✅ Two or more base gaskets in different thicknesses to optimize compression ratio
• ✅ Built for race prep and mid-season engine freshening

Benefits of use:

• 🔹 Helps reduce the risk of leaks during a top-end service with high-quality sealing components
• 🔹 Lets you tailor compression for your riding and fuel choice (standard vs. race fuel)
