§ 02 / About this part

What it is

Athena complete gasket kit to fit Gas Gas EC250F (2013–2015); Gas Gas EC300F (2013–2015); Yamaha WR250F (2001–2013); Yamaha YZ250F (2001–2013).

Use this kit for full engine teardowns and bottom-end rebuilds on your bike. It provides every seal needed to close the crankcases, clutch cover, and ignition side. These components eliminate the risk of oil leaks or air intake leaks after you split the cases. Each part matches OEM dimensions to ensure a flush fit under high thermal stress. Install these when replacing main bearings or the crankshaft to keep the entire unit airtight. Always cross-reference your model year to ensure exact port matching. Clean all mating surfaces thoroughly to avoid a pinch or failure during assembly.

§ 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.
