§ 02 / About this part

What it is

ProX exhaust valve and spring kit to fit the KTM EXC-F 250, model year 2007, and KTM SX-F 250, model years 2006–2007.

This kit provides a complete refresh for your exhaust circuit. It includes both the valve and a matched spring set. Using matched springs ensures correct seat pressure and prevents valve float at high RPM. This is a common upgrade when converting from titanium to steel for better longevity. Install these during a top-end overhaul to maintain engine compression. Ensure the valve guides are within spec before fitting. It is a model-specific fitment designed for the rigours of MX and enduro.

§ 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.
