§ 02 / About this part

What it is

The PRO CIRCUIT SILENCER R304 1151930, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This short-canister silencer is built for maximum power gains in the lower to mid-range. It is the preferred choice for motocross where instant throttle response is critical. The unit bolts to the subframe and connects to the expansion chamber. The compact length reduces the risk of damage during crashes. Two-stroke silencers need frequent repacking to prevent the core from burning out. Use high-quality packing material to maintain the distinct race-tuned sound. This part is model-specific and designed to fit the original mounting points without modification.

§ 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.
