§ 02 / About this part

What it is

Athena top-end gasket kit to fit Yamaha WR250F (2015–2018); Yamaha YZ250F (2014–2018); Yamaha YZ250FX (2015–2019).

This kit provides the essential seals for a top-end refresh on your Yamaha. It includes the head gasket, base gasket, and necessary O-rings for the cylinder and exhaust. These components endure extreme thermal cycling and combustion pressure. They must be replaced every time you pull the head for a piston change. Reusing old gaskets leads to coolant leaks and lost compression. Ensure both the deck and head surfaces are perfectly flat. Follow the factory torque sequence to ensure an even seal across the bore.

§ 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.
