§ 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.

This kit replaces the intake components in your cylinder head during a top-end rebuild. High-velocity air and fuel wash eventually wear the valve faces, leading to hard starting and loss of power. This kit includes steel valves and matched heavy-duty springs to restore factory performance. Steel conversions provide a longer service life for riders prioritising durability over marginal weight savings. Ensure your valve seats are checked for a perfect seal before installation. Always fit new stem seals when rebuilding the head to prevent oil leaking into the combustion chamber.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
