§ 02 / About this part

What it is

Wiseco steel intake valve to fit Yamaha WR400F (1998–2000); Yamaha YZ400F (1998–1999); Yamaha YZ426F (2000).

This steel intake valve is a durable alternative to titanium components. It sits in the cylinder head to control the air-fuel mixture entering the bore. Steel valves are preferred for enduro and trail riding where longevity is more important than absolute weight savings. They resist cupping better than titanium in dusty conditions. When installing, you must use the correct heavy-duty valve springs designed for steel valves. Always check the valve seat condition and lap the valves if necessary. This part provides a reliable, long-term solution for your top-end rebuild.

§ 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.
