§ 02 / About this part

What it is

The FMF POWERCORE 4 HEX SLIP-ON MUFFLER ALUMINUM YAMAHA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This slip-on silencer is engineered to increase the power output of your Yamaha four-stroke across the entire RPM range. The hexagonal aluminium canister provides a larger internal volume, which helps manage sound levels while allowing for a high-flow core. It is a robust upgrade for riders looking to replace a heavy or damaged stock unit. The stainless steel mid-pipe ensures a secure fit to the header. For optimal performance, ensure the exhaust gaskets are in good condition during installation. Repack the core at regular service intervals to maintain the acoustic dampening.

§ 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.
