§ 02 / About this part

What it is

Wiseco engine rebuild kit Pro-Lite to fit the Yamaha YZ125, model year 2001.

A cases-split rebuild for the YZ 125 without hunting parts from three suppliers. Wiseco packs the forged Pro-Lite piston, rings and small-end bearing alongside a complete crank assembly, main bearings, seals and every gasket the job needs. The 125's rod and big-end wear on the same clock as the bore, so replacing the lot restores factory clearances throughout. Clean the cases thoroughly, check ring end gap before the barrel goes on, and the engine leaves the bench as tight as it left Japan.

§ 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.
