§ 02 / About this part

What it is

Wiseco piston kit to fit the Yamaha YZ250F, model years 2008–2011.

This forged piston kit provides increased strength for high-load racing conditions. It replaces the stock unit in your top-end. Forging allows for a lighter design without sacrificing structural integrity. This kit is essential when your service interval indicates a drop in compression or visible skirt wear. It includes all necessary rings, pins, and clips for a complete swap. Check your bore for taper and ovality before fitting. Follow a strict break-in procedure to ensure the rings seat correctly against the cylinder wall.

§ 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.
