§ 02 / About this part

What it is

The WISECO ENGINE REBUILD KIT PRO-LITE, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

The YZ 125 is the classic two-stroke rebuild platform, and this kit covers the whole job. Forged Pro-Lite piston with rings and small-end bearing, complete crankshaft assembly, main bearings, seals and a full gasket set to seal the cases and top-end. When the big-end shows play or the piston skirt is scored, doing both ends together beats chasing failures one at a time. Measure ring gap in the bore, lubricate the mains and follow Yamaha's torque sequence on reassembly.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
