§ 02 / About this part

What it is

The PROX VALVE AND SPRING INTAKE KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

These components sit in the cylinder head and manage the gas flow of your four-stroke engine. High RPM and heat eventually cause valve faces to cup and springs to fatigue. This leads to difficult starting and lost compression. These steel components provide a durable alternative to OEM titanium parts for long-distance enduro or practice days. You must inspect the valve seats for wear before fitting. Ensure the head is clean and seats are cut or lapped for a perfect seal. This kit includes matched springs to manage the specific weight of these valves.

§ 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.
