§ 02 / About this part

What it is

The FMF MUFFLER S/S ALM 4.1 RCT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This muffler features Resonance Chamber Technology to optimise exhaust pressure and increase power. The stainless steel mid-pipe and aluminium canister provide a durable, race-ready setup. It shortens the overall length to move weight forward, improving the handling of your bike. It fits the stock header and mounts to the subframe. The design allows for easy maintenance and repacking. Check the mounting bolts after the first ride to ensure they remain tight under vibration. This unit is designed for riders who want factory-level performance and a broader powerband on the track.

§ 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.
