§ 02 / About this part

What it is

The ATHENA PISTON KIT FORGED Ø53,96mm, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Forged construction offers superior strength for high-revving 125cc engines. This kit replaces the stock unit to handle the rigours of race conditions. It sits within the top-end and dictates the engine's compression ratio. Replace your piston at the recommended hour interval to avoid fatigue. The forged material expands differently than cast, so adhere strictly to warm-up procedures. This kit includes the piston, rings, pin, and clips. Verify your cylinder bore measurement matches the 53.96mm specification. Always use a fresh base gasket during the rebuild process to ensure a proper seal.

§ 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.
