§ 02 / About this part

What it is

Moose Offroad complete gasket set to fit Yamaha WR450F (2016–2018); Yamaha YZ450F (2014–2017); Yamaha YZ450FX (2016–2019).

This kit provides every seal required for a full bottom-to-top engine overhaul. It includes crankcase gaskets, top-end seals, and copper washers for the oil circuit. Use this when splitting the cases to replace main bearings or the gearbox. Reusing old gaskets during a rebuild is a primary cause of oil leaks and vacuum issues. Each component is cut to precise dimensions for Yamaha fitment. Clean all surfaces of old residue to ensure the new seals seat correctly. It is the standard choice for a comprehensive winter workshop project.

§ 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.
