§ 02 / About this part

What it is

The PROX VALVE EX TITAN YZF450, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This titanium exhaust valve is built for the demanding top-end of your YZF450. It sits in the exhaust port and handles extreme heat while maintaining low reciprocating weight. Titanium is essential for the high-revving nature of this engine. These valves are consumables in a race environment and must be replaced when clearances start to tighten consistently. The special coating on the valve face must remain intact. Never use lapping paste on these valves. Direct fitment ensures your bike maintains its factory power delivery.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. Brands you'd find on a paddock workbench — pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere; dirt and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
