Vertex Pistons 20-24 WR 250 F/19-24 YZ 250 F/20-24 YZ 250 FX Top End Gasket Kit

This top-end gasket kit from Vertex Pistons is built with materials designed to handle the heat and pressure of your WR 250 F, YZ 250 F, or YZ 250 FX engine. When you're rebuilding the top end of your motorcycle, having all the right seals and gaskets in one place makes the job much smoother. This kit aims to provide everything you need to get your engine sealed up properly after you've replaced your pistons or cylinder components.

Vertex has put together a comprehensive set here, including every gasket, o-ring, and seal necessary for a complete top-end overhaul. For multi-cylinder machines, they've included enough components to service all cylinders, ensuring a consistent seal across the board. It's worth noting that this kit does not include the formed rubber valve cover gasket, so you'll want to check if yours is reusable or needs to be sourced separately.
