§ 02 / About this part

What it is

Pro Circuit Works 2-stroke exhaust pipe to fit Yamaha YZ125 (2021–2027); Yamaha YZ125X (2022).

This raw, hand-welded expansion chamber improves power delivery across the entire rev range. It is designed for two-stroke engines to increase throttle response and top-end over-rev. The unplated finish requires regular maintenance with oil to prevent surface rust after washing. It replaces your dented or restricted OEM pipe. Ensure your jetting is correct after fitting to account for the increased flow. This pipe is built for the track where performance outweighs aesthetics. It fits specific models for a precise bolt-on installation.

§ 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.
