§ 02 / About this part

What it is

The FMF FATTY PIPE NICKEL-PLATED STEEL KTM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This expansion chamber broadens the power delivery across the entire rev range. It smooths out the transition from the mid-range into the top-end over-rev. The nickel-plated finish provides a durable barrier against corrosion and roost, making it a practical upgrade for UK winter riding. It replaces the restrictive stock pipe and matches the original mounting points on your KTM. Use new O-rings at the exhaust port to ensure a gas-tight seal. This is a direct fitment for your engine, designed to work with either the stock silencer or an aftermarket unit.

§ 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.
