§ 02 / About this part

What it is

ProX intake valve and spring kit to fit Gas Gas EC 250 4T (2010–2011); Gas Gas EC 250 RACING (2010–2011); Gas Gas EC 250 SIXDAYS (2010–2011); Gas Gas EC250 (2010–2011); Gas Gas EC250E (2011); Gas Gas EC250F (2012–2015); Gas Gas EC300F (2013–2015); Yamaha WR250F (2001–2013); Yamaha YZ250F (2001–2013).

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.
