The Athena Race Gasket Kit is designed for 1999–2004 Yamaha YZ125 two-stroke motorcycles. Developed for racers and performance-focused riders, this kit provides the reliable sealing and precise fit needed during engine rebuilding or top-end service. Athena manufactures these gaskets to support dependable performance while offering a practical alternative to purchasing individual components separately.
Kit contents include a multi-layer steel head gasket and two base gasket options: one stock-thickness gasket and one high-compression gasket. This selection allows you to choose the configuration that best matches your engine setup and performance goals. The gaskets use the same quality construction found in Athena top-end and complete engine gasket kits.
