§ 02 / About this part

What it is

The FMF FACTORY FATTY PIPE RAW STEEL SUZUKI, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This expansion chamber is designed for pure race performance with a raw steel finish. It provides a significant increase in power across the entire rev range, particularly in the mid-to-top end. The unplated steel requires regular maintenance with oil or WD40 to prevent surface rust. It fits directly to the cylinder port and uses your bike's original mounting points. Hand-welded seams ensure a precise fit and optimal flow characteristics. This is the ideal choice for competitive MX riders who want the lightest possible setup and maximum power output from their engine.

§ 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.
