§ 02 / About this part

What it is

Kibblewhite Black Diamond exhaust valve to fit Honda CRF250R (2010–2015).

This exhaust valve sits in the cylinder head and manages the exit of hot combustion gases. Constant thermal cycling causes the stem to stretch and the face to pit over time. This direct replacement matches OEM specifications for fitment and performance. It is essential to check valve guides for wear and ensure the seat is true before fitting. Cross-references with OEM part 14721-KRN-A40 for a precise match. Replacing worn valves restores compression and prevents catastrophic engine failure during high-RPM use. Always use new stem seals for every 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.
