This top-end gasket kit from Vertex Pistons contains every gasket, o-ring, and seal you'll need to get your 2005-2021 Yamaha YZ125's engine back in top shape. When you're rebuilding the top end, having all the correct seals and gaskets in one place makes the job much smoother. This kit is designed to cover all the bases for a complete top-end overhaul.

Vertex is a well-known name in performance engine components, and this kit reflects that. It's put together to ensure you have the right parts for a proper seal after you've finished your cylinder work.

Note that this kit does not include a formed rubber valve cover gasket, so be sure to check if your specific application requires one separately.
