§ 02 / About this part

What it is

Kibblewhite Black Diamond exhaust valve to fit Yamaha WR250F (2001–2013); Yamaha WR450F (2003–2009); Yamaha YZ250F (2001–2013); Yamaha YZ450F (2003–2009).

This Black Diamond exhaust valve is built to withstand the extreme temperatures of the exhaust stroke. The nitride coating provides a low-friction surface that resists the abrasive effects of carbon deposits. Forged from stainless steel, this valve is significantly more durable than OEM titanium versions, making it less prone to face recession. It is a vital upgrade for any high-performance top-end rebuild. Always use new valve stem seals and check your guide clearances when installing these valves to ensure long-term reliability and performance.

§ 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.
