§ 02 / About this part

What it is

The FMF MUFFLER S/S ALUM FACTORY 4.1 RCT CARBON CAP KX450F, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This muffler uses Resonance Chamber Technology to increase exhaust volume and improve flow. The stainless steel mid-pipe and aluminium canister provide a durable, high-performance solution for 4-stroke racing. The carbon fibre end cap reduces weight at the furthest point of the bike. It fits the stock header or a matching aftermarket pipe. The design allows for easy removal of the insert or spark arrestor if required. Monitor the carbon cap for signs of fatigue and repack the canister to protect the outer sleeve.

§ 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.
