§ 02 / About this part

What it is

The ATHENA GASKET KIT FOR ATHENA CYLINDER KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

These gaskets are specifically sized for your aftermarket cylinder setup. They differ from standard OEM dimensions to accommodate the revised bore or porting. Use these when performing routine maintenance or replacing the piston in your existing kit. The base gasket sets your squish clearance, which is critical for engine timing and detonation control. Always measure your squish after installation to confirm the tolerances. Keep the mating surfaces dry and clean during the build. This ensures the seals hold under high-rev race conditions.

§ 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.
