§ 02 / About this part

What it is

Athena forged piston kit Ø81.95 mm to fit Honda CRF250R (2004–2009); Honda CRF250X (2004–2009).

This forged piston kit is designed for 4-stroke top-end maintenance. It sits in the cylinder bore to manage the compression and power strokes of your engine. The 81.95mm size is engineered for precise fitment and optimal oil control. Forged units offer superior durability under high heat cycles compared to cast alternatives. The kit includes the piston, rings, gudgeon pin, and circlips. Deglaze the cylinder bore before fitting the new assembly to ensure the rings seat correctly. Regular replacement is essential for maintaining peak torque and engine reliability.

§ 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.
