§ 02 / About this part

What it is

ProX crankshaft oil seal kit to fit the Yamaha YZ65, model years 2018–2026; Yamaha YZ85LW, model years 2019–2023; and Yamaha YZ85SW, model years 2019–2023.

The crankshaft seals are the most critical barriers in your bottom end. On two-strokes, they maintain primary compression and prevent gearbox oil from entering the combustion chamber. On four-strokes, they manage oil pressure around the crank journals. These seals endure extreme heat and high RPM, making them a mandatory replacement during any crank service or bottom-end rebuild. This kit provides a direct cross-reference to OEM specifications for a reliable fit. Use a seal driver to ensure they sit perfectly flush. Lubricate the inner lips to avoid burning the rubber on the first kick.

§ 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.
