§ 02 / About this part

What it is

The KIBBLEWHITE VALVE BLACK DIAMOND EXHAUST, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

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 — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
