§ 02 / About this part
What it is
The PROX ENGINE VALVE EXHAUST STEEL, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
Steel construction offers a durable solution for the high-heat environment of your exhaust circuit. This part sits in the cylinder head and manages the exit of spent gases from the bore. Exhaust valves endure extreme thermal stress, which eventually leads to face erosion or stem stretch. Replacing these components during a top-end rebuild prevents catastrophic failure and restores engine efficiency. This fitment matches OEM cross-reference 3YF-12121-00. Steel provides a longer service life than titanium for heavy-duty use. Ensure the valve is correctly lapped into the seat to maintain a gas-tight seal.
