§ 02 / About this part

What it is

The PRO CIRCUIT MUFFLER R304 1161985, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

The R304 is a shorty-style silencer designed to provide maximum bottom-to-midrange power. It is ideal for tight tracks where quick acceleration out of corners is essential. The compact aluminum canister reduces weight and sits tucked in against the subframe. Because of its size, the packing should be checked frequently to ensure optimal performance. It is a direct bolt-on for two-stroke bikes and works best with a matching race pipe. This silencer is intended for closed-course competition. It gives the bike a distinct, aggressive race tone and sharper throttle feel.

§ 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.
