The Athena P400270600043 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who refresh their engine before a race or during the riding season. This KTM-compatible gasket kit provides the essential top-end sealing components needed for dependable engine service and performance-focused maintenance.
The kit includes a premium MLSS head gasket and two or more high-quality base gaskets in different thicknesses.
