§ 02 / About this part

What it is

The TWIN AIR POWER FLOW KIT CRF250-450 '25, air filters. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit replaces the stock CRF cage with a rigid frame. It removes the restrictive backfire screen for better throttle response. The kit includes a flame-resistant foam filter designed to work without the screen. It provides a more secure seal against the airbox than the OEM setup. This is a performance upgrade for the 2025 CRF250 and CRF450. The aluminium cage ensures the filter remains in the correct position under heavy load. It allows for increased air volume to reach the intake for improved power delivery.

§ 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.
