§ 02 / About this part

What it is

Pro Circuit 304 Factory Sound silencer to fit Sherco SEF 300 (2025–2026).

This silencer replaces the restrictive OEM unit to improve exhaust flow and power delivery. It mounts to the subframe and connects directly to your expansion chamber. The longer canister design provides a broader power increase across the entire rev range compared to shorter versions. It is a staple for track use where consistent performance is required. Silencer packing is a consumable item and should be replaced every 15 hours to maintain backpressure. Check the rubber mounting grommets for wear during installation to prevent vibration-induced cracking.

§ 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.
