§ 02 / About this part

What it is

The PROX ENGINE VALVE EXHAUST STEEL, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This steel exhaust valve serves as a direct replacement for OEM part 14721-MEB-670. It is engineered to meet the original specifications for fitment and performance. Steel construction provides a longer service life than titanium, especially in engines that see high hours of trail or track use. It sits in the exhaust port and must maintain a perfect seal against the seat to preserve compression. Use this valve for a cost-effective and durable top-end refresh. Ensure your valve springs are in good condition to manage the steel valve weight.

§ 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.
