§ 02 / About this part

What it is

ProX crankshaft oil seal kit to fit the Yamaha YZ125, model years 2005–2027, and Yamaha YZ125X, model years 2020–2027.

Replace your crankshaft seals as a pair with this dedicated kit. These components sit on either side of the crank to maintain the integrity of the combustion chamber and gearbox separation. If these fail, you risk air leaks or oil transfer, both of which compromise performance. They are a mandatory requirement whenever the cases are split for a crank or bearing change. Each seal is built to OEM specifications for a precise press-fit. Ensure the crank journals are polished and clean to prevent premature wear on the new rubber lips.

§ 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.
