§ 02 / About this part

What it is

The FMF MUFFLER FACTORY 4.1 RCT TITANIUM ANODIZED SL (Slip-On) W/ CARBON CAP, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This titanium slip-on significantly reduces weight at the rear of your bike to improve handling. The Resonance Chamber Technology manages sound waves to meet track limits while broadening the powerband. It features an anodized finish and a carbon fibre end cap for a factory look. This unit slides directly onto your stock header. Titanium construction offers superior heat dissipation compared to standard steel. Monitor the internal muffler packing every fifteen hours of hard use. Fresh packing maintains the correct back pressure for your engine. This is a technical upgrade for riders looking to sharpen power delivery.

§ 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.
