§ 02 / About this part

What it is

The FMF HEADER S/S M-BMB CRF450X, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This stainless steel header is built for the CRF450X to improve low-end grunt. The expansion chamber increases the internal volume to help exhaust scavenging at low RPM. It mounts directly to the cylinder head and runs through to the mid-section. Stainless steel is used for its resistance to corrosion and impact damage on the trail. Replace your copper exhaust gasket during the install to ensure a proper seal. This header also helps quieten the bike by acting as a resonator. It fits with the standard silencer or compatible slip-ons.

§ 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.
