Athena 21-23 Gas Gas MC 125 53.94mm Bore Cast 2-Stroke Top End Piston Kit w/Top End Gasket Kit

If you're rebuilding the top end of your Gas Gas MC 125, this Athena kit is a solid option. It bundles a cast 2-stroke piston with a complete top end gasket set, so you have everything you need for a perfectly matched repair. Athena handles the development of both the piston and its compatible gaskets internally, ensuring they work together for optimal performance and reliability after installation.

The piston in this kit has a 53.94mm bore, which is the standard size for the MC 125. Using a cast piston means it's well-built for everyday riding and offers good durability. When you replace your piston, using a gasket kit designed specifically for it, like this one, helps ensure a proper seal and maintains the engine's compression. This combination is designed to give you high performance and keep your engine running reliably.
