§ 02 / About this part

What it is

Athena forged piston kit Ø66.36 mm for selected Gas Gas, Husqvarna and KTM models. Check the fitment table for exact models and years.

This forged kit provides enhanced durability for 250cc two-stroke engines. The forging process creates a denser grain structure, making it more resistant to the stresses of hard enduro or motocross. It sits in the top-end and is essential for maintaining the power delivery of your bike. Replace this kit when compression begins to drop or at the hour limit. The kit includes the piston, rings, gudgeon pin, and circlips. Check the ring end gap in the cylinder before installation. Ensure the cylinder bore is clean and deglazed to allow the new rings to bed in correctly.

§ 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.
