§ 02 / About this part

What it is

ProX crankshaft bearing and seal kit to fit the Honda CR125R, model years 1986–2007.

This kit provides the main bearings and oil seals required for a full bottom-end refresh. These components sit deep in the engine cases to support the crank and maintain primary compression. Seals eventually harden or tear, leading to air leaks and lean running. Bearings develop play over high race hours. Replacing the full set ensures your crank rotates true and the crankcase remains airtight. These kits match OEM dimensions for a direct swap during a rebuild. Use a proper press and heat cycle the cases for installation. Fresh seals are vital for consistent jetting and engine longevity.

§ 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.
