§ 02 / About this part

What it is

Athena gasket kit for Athena cylinder kit to fit Yamaha WR250F (2001–2012); Yamaha YZ250F (2001–2012).

This kit is specifically for bikes running an aftermarket cylinder. It includes the unique bore-size head gasket and base gaskets required for that specific casting. Standard OEM gaskets will not fit this application. Use these when performing routine piston maintenance or if you have removed the head for inspection. Correct gasket thickness is vital for maintaining the intended port timing and compression ratio. Ensure the dowels are correctly seated before torquing the head bolts to specification.

§ 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.
