§ 02 / About this part

What it is

Wossner replacement main bearing to fit Gas Gas MC50 (2021); KTM SX50 (2006–2017); Yamaha PW50 (1982–1983, 1985–1988, 1991–2008, 2010–2016).

This main bearing supports the crankshaft at the heart of your lower engine. It seats directly into the crankcase to manage the radial loads of the rotating assembly. High hours and race conditions eventually cause internal play or surface fatigue. Replace this component during a top-to-bottom rebuild to maintain precise crank alignment. Proper installation requires splitting the cases and using heat to seat the outer race. This bearing matches OEM tolerances to ensure your crank spins true without vibration. It is a critical part for restoring engine balance and 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.
