§ 02 / About this part

What it is

The K & N AIR FILTER YZ250F/450F/FX, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This pleated air filter provides increased airflow for your intake system. It sits in the airbox and replaces the standard foam element. The design cross-references with OEM parts B3J144511000 and BR9144510000. It is suited for riders seeking improved throttle response on hard-pack tracks. The filter uses a specific sealing surface to prevent leaks. Clean and recharge the media according to your service schedule. Ensure the airbox is free of debris before fitting this unit.

§ 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.
