§ 02 / About this part

What it is

Moose Offroad standard top-end gasket set to fit the Yamaha WR400F, model years 2000–2001; Yamaha WR426F, model years 2001–2002; and Yamaha YZ426F, model years 2000–2002.

A top-end rebuild requires a reliable seal to maintain compression and prevent leaks. This set includes the necessary gaskets for the cylinder head and base. These are manufactured to OEM specifications to ensure a precise fit on your engine. Replace these every time you pull the head for a piston change or valve inspection. Clean the mating surfaces thoroughly before installation to avoid any sealing issues. Using fresh gaskets is the only way to guarantee the integrity of your top-end assembly after maintenance. It is a vital part of your service interval kit.

§ 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.
