§ 02 / About this part

What it is

Athena gasket kit for Athena cylinder kit to fit Yamaha YZ250 (2013–2021).

These seals are specific to your aftermarket cylinder setup. They accommodate the specific bore and port dimensions of that kit. Standard OEM gaskets will not fit correctly. Use these for scheduled top-end maintenance or piston swaps. The kit includes the head gasket, base gasket, and necessary O-rings. Check your squish clearance after fitting the base gasket to ensure optimal performance. Always replace the exhaust gasket to prevent power-robbing leaks.

§ 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.
