§ 02 / About this part

What it is

Wiseco crankshaft kit to fit the Yamaha YZ250, model years 1999–2000.

This assembly is the core of your bike's lower engine. It sits in the crankcases and converts the vertical movement of the piston into rotation. You will need to replace this if the big-end bearing fails or during a high-hour service. The kit includes the crank, main bearings, and gaskets for a complete job. Factory engineering ensures the unit matches the balance and weight of the original part. When installing, ensure the woodruff key for the flywheel is seated correctly. A fresh bottom end is vital for maintaining the performance and longevity of your engine.

§ 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.
