§ 02 / About this part

What it is

The FMF FACTORY 4.1 RCT SLIP-ON MUFFLER TITANIUM & CARBON BLUE ANODIZED KAWASAKI, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This slip-on uses Resonance Chamber Technology to reduce decibel levels while maintaining a high flow rate. The titanium construction and carbon fibre end cap significantly reduce weight at the rear of your Kawasaki. It alters the exhaust pressure wave to improve power across the entire curve. This unit is designed for closed-course competition where every gram and horsepower counts. The blue anodized finish requires careful cleaning with mild detergents to avoid staining from harsh workshop chemicals. Regular repacking is necessary to protect the finish from heat discolouration.

§ 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.
