§ 02 / About this part

What it is

The PRO CIRCUIT MUFFLER 304 KTM 125 SX, slip-ons. Stocked by Iron Offroad, the UK MX hard parts specialist.

This silencer is engineered to broaden the powerband of your 125 SX. The design features a slightly longer canister than the shorty version, providing better top-end over-rev for fast tracks. It uses a stainless steel stinger and an aluminium body for a lightweight, durable finish. The unit bolts directly to your subframe and expansion chamber. Maintaining the internal packing is critical for small-capacity 2-strokes to ensure consistent back pressure. Inspect the silencer after every few hours of track time. This is a proven performance upgrade for competitive racing.

§ 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.
