§ 02 / About this part

What it is

Moose Offroad complete gasket set with oil seals to fit the Yamaha YZ250, model years 2002–2024, and Yamaha YZ250X, model years 2016–2024.

This set provides every gasket and oil seal required for a total engine overhaul. It covers the top-end, lower-end, and all outer covers. Use this when splitting the cases or performing a full seasonal rebuild to ensure a leak-free seal across the entire block. The kit includes critical crank seals and valve stem seals where applicable. All components meet or exceed OEM specifications for fitment and thermal resistance. Clean all mating surfaces thoroughly before installation. Avoid using liquid sealant on these gaskets to prevent internal oil gallery blockages.

§ 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.
