§ 02 / About this part

What it is

Moose Offroad standard top-end gasket set to fit the Yamaha YZ125, model years 2005–2021, and Yamaha YZ125X, model years 2020–2022.

Refresh your top-end with this specific gasket set. It contains the head gasket, base gasket, and all required O-rings for a cylinder service. If your bike is a four-stroke, it includes valve stem seals to prevent oil consumption. For two-strokes, it covers the power valve assembly seals. Gaskets are consumables that must be replaced whenever the cylinder is removed to maintain compression and cooling efficiency. These parts are cut to exact OEM dimensions for a drop-in fit during your next scheduled top-end rebuild.

§ 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.
