§ 02 / About this part

What it is

Pro Circuit 304 Factory Sound silencer to fit Gas Gas MC 85 17/14 (2025–2027); Gas Gas MC 85 19/16 (2025–2027); Husqvarna TC 85 17/14 (2025–2026); Husqvarna TC 85 19/16 (2025–2026); KTM SX 85 17/14 (2025–2026); KTM SX 85 19/16 (2025–2027).

This two-stroke silencer features a longer canister design to provide a classic power increase while managing noise levels. It sits at the rear of the exhaust tract, connecting to the expansion chamber. The aluminium body and stainless steel intake tube resist corrosion in wet UK conditions. It is a direct fit for the specified model. Internal packing degrades over time, leading to power loss and increased decibels. Replace your worn unit to restore back-pressure and throttle response.

§ 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.
