§ 02 / About this part

What it is

The WISECO ENGINE REBUILD KIT, engine. Stocked by Iron Offroad, the UK MX hard parts specialist.

A full bottom-to-top rebuild in one box: crankshaft, main bearings, seals, piston assembly and a complete gasket set for the YZ 250 F. High hour counts fatigue the big-end bearing and piston skirt together, so replacing the lot keeps tolerances matched across the whole rotating assembly rather than putting a fresh top-end on a tired crank. Split the cases with a proper case splitter, deburr the mating surfaces, and it goes back together at factory compression with the bottom-end vibration gone.

§ 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.
