§ 02 / About this part

What it is

The FMF FACTORY FATTY PIPE RAW STEEL KTM, full systems. Stocked by Iron Offroad, the UK MX hard parts specialist.

This full system for your KTM features a raw steel expansion chamber for a factory-level weight and feel. The unplated steel allows for better heat dissipation but requires consistent oiling to prevent surface corrosion. It is designed to maximize the power output of your 2-stroke engine across the entire RPM range. Replacing the full system ensures that the expansion chamber and silencer are perfectly tuned to each other. Check your mounting brackets and rubber dampers for wear before installation to ensure the system is properly supported against engine vibration.

§ 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.
