§ 02 / About this part

What it is

ProX intake valve and spring kit to fit the Kawasaki KX450F, model years 2009–2018.

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 — 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.
