§ 02 / About this part

What it is

Wiseco piston kit to fit the Yamaha IT 250, model years 1981–1983, and Yamaha YZ250, model years 1980–1982.

Refresh your engine with this complete top-end kit. It features a forged piston designed for high-stress racing conditions. The kit provides the rings, pin, and clips needed for a full swap. Monitor your hour meter to stay within recommended service intervals. Measure your cylinder bore to ensure this 71.00mm size matches your current setup. A fresh piston restores lost power and ensures reliable operation during your next moto. Always lubricate the wrist pin and rings with assembly oil during the install.

§ 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.
