Honda TRX450R Top End Gasket Kit — Vertex Pistons (’04–’05). A complete top-end gasket set designed to replace all necessary gaskets, o‑rings and seals for a proper rebuild of the TRX450R cylinder head and upper assembly.

This Vertex Pistons kit supplies the components you need to refresh the top end without sourcing individual seals. It includes gaskets, o‑rings and seals required to rebuild the top end; multi‑cylinder machines receive enough components to rebuild all cylinders. The kit is intended for 2004–2005 Honda TRX450R models and helps ensure correct sealing surfaces after disassembly, reducing the chance of leaks and simplifying reassembly for experienced mechanics and DIY enthusiasts alike. Note: it does not include the formed rubber valve cover gasket.
