§ 02 / About this part

What it is

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

This titanium intake valve is a critical part of your YZF450 top-end. It sits in the intake port to control the air-fuel charge. The lightweight titanium construction is vital for high-RPM stability and performance. Monitor your valve clearances closely, as tightening indicates the valve face is wearing. Replace these valves as a set during a top-end rebuild. Do not lap titanium valves, as this will strip the hardened surface layer. It is a precise fitment designed to meet the rigorous demands of racing.

§ 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.
