Yamaha WR450F Top End Gasket Kit - Vertex Pistons - `19-`20. This Vertex top end gasket kit is designed for 2019–2020 WR450F applications and provides the sealing components needed for a proper top-end rebuild.

The kit contains precision-cut gaskets, o-rings and seals engineered to match factory tolerances and help restore proper sealing surfaces after cylinder work. It is intended to include every gasket, o-ring and seal required to rebuild the top end of a WR450F; note that the formed rubber valve cover gasket is not included. Ideal for enthusiasts performing piston, ring, or head service, the kit saves time sourcing individual parts and reduces the risk of missing small seals during reassembly.
