§ 02 / About this part

What it is

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

This expansion chamber broadens the powerband across the entire rev range. It replaces the restrictive OEM unit to improve over-rev and throttle response. The raw steel finish requires regular maintenance to prevent corrosion. Wipe it down with an oily rag after washing your bike to maintain the factory look. It fits directly to the cylinder exhaust port using your existing springs and O-rings. Check your jetting after installation to ensure the air-fuel mixture compensates for the increased flow. This is the standard choice for MX tracks where maximum power delivery is the priority.

§ 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.
