§ 02 / About this part

What it is

The FMF MUFFLER Q4 HEX KX250'21, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This muffler is engineered for riders needing to meet strict sound requirements without sacrificing performance on the KX250. It features a complex internal baffle system and a spark arrestor for trail and enduro use. The hex-shaped canister increases internal volume for better noise damping. It sits on the right-hand side of the subframe and bolts up to the OEM header. This is the correct choice for green lanes or noise-sensitive tracks. Periodic maintenance of the spark arrestor screen is necessary to prevent carbon build-up and power loss.

§ 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.
