§ 02 / About this part

What it is

Athena forged piston kit Ø82.96 mm to fit Yamaha WR250F (2001–2012); Yamaha YZ250F (2001–2007).

This forged piston kit sits at the top of the connecting rod in your 4-stroke engine. The 82.96mm diameter provides a precise fit for your top-end rebuild. Forged construction ensures the piston can withstand the high pressures of competitive racing or trail use. Replacing the assembly restores lost compression and prevents oil blow-by. The kit includes the piston, rings, gudgeon pin, and circlips. Clean the ring grooves thoroughly and check the ring end-gap before installation. It is a critical component for maintaining the performance and longevity of your bike.

§ 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.
