§ 02 / About this part

What it is

The FMF MEGABOMB HEADER STAINLESS STEEL, mid pipes. Stocked by Iron Offroad, the UK MX hard parts specialist.

This stainless steel header incorporates a resonance chamber to increase exhaust surface area and boost torque. It replaces the stock header at the cylinder head to broaden the power delivery. The stainless construction is robust and handles the heat cycles of high-performance 4-stroke engines without degrading. It is a model-specific fitment designed to work with OEM or aftermarket silencers. Use a new exhaust gasket to ensure a proper seal at the port. This header is an effective way to improve low-end pull for better drive out of corners on the track.

§ 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.
