§ 02 / About this part

What it is

Wiseco piston kit Pro-Lite to fit the Yamaha YZ125, model years 1990–1992.

This lightweight forged piston kit reduces reciprocating mass in your top-end. It is designed for high-revving engines where throttle response is critical. The forged alloy maintains its shape under extreme thermal stress. Replace your piston when the service manual hours are reached to prevent catastrophic skirt failure. The kit includes the piston, rings, pin, and circlips. Measure your cylinder to ensure the clearance meets the specified tolerances. This kit is a staple for competitive track and woods use.

§ 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.
