§ 02 / About this part

What it is

Pro Circuit Platinum 2-stroke exhaust pipe to fit Yamaha YZ125 (2005–2021); Yamaha YZ125X (2020–2021).

This expansion chamber uses electroless nickel plating to resist the corrosive effects of UK mud and jet washing. It sits between the cylinder exhaust port and the silencer, providing a significant increase in mid-range torque and top-end over-rev. The plating eliminates the need for constant oiling after every wash. It is a direct replacement for your OEM pipe. Ensure you use new O-rings at the manifold to prevent air leaks. This part suits riders looking for a broad powerband without the maintenance of a raw finish.

§ 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.
