§ 02 / About this part

What it is

Moose Offroad complete gasket set with oil seals to fit the Yamaha YZ450F, model years 2003–2005.

This kit provides the seals required for a full engine teardown and rebuild. It covers the top-end, lower-end, and critical oil seals. Use this when splitting the cases to replace a crank or gearbox components. It includes the base gasket, head gasket, and necessary O-rings for the water pump and ignition cover. Replacing every seal during a major service prevents vacuum leaks and oil pressure drops. These parts meet OEM specifications for thickness and material. Ensure all surfaces are flat and free of old gasket material before assembly to prevent leaks.

§ 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.
