§ 02 / About this part

What it is

ProX crankshaft bearing and seal kit to fit KTM SX 50 (2009–2012); KTM SX 50 MINI (2009–2012).

This kit provides the main rotating supports and the required oil seals for a full rebuild. These parts support the crankshaft and ensure smooth rotation under heavy load. The seals are vital for maintaining primary compression on two-strokes and preventing oil migration on four-strokes. Replace these whenever the cases are split for service. Worn internals lead to vibration and eventual crank failure. These parts match OEM dimensions for a direct swap. Use a press or heat-shrink method for installation to avoid damaging the races or the engine cases.

§ 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.
