§ 02 / About this part

What it is

The FMF MUFFLER Q4 HEX KX250'21, slip-ons. 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 — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
