§ 02 / About this part

What it is

Athena complete gasket kit with oil seals to fit Yamaha WR450F (2016–2018); Yamaha YZ450F (2014–2017); Yamaha YZ450FX (2016–2018).

This kit covers every seal and gasket required for a full engine overhaul. It includes the top-end gaskets, crankcase seals, and all peripheral O-rings. Use this when splitting the cases for a crank replacement or gearbox repair. These components meet OEM tolerances to ensure a leak-free build. Replacing every seal at once prevents the need to pull the engine again for a minor weep. Lubricate the oil seal lips before sliding them over the shafts. This kit is essential for restoring factory-level sealing to your bike.

§ 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.
