§ 02 / About this part

What it is

Wiseco engine rebuild kit Pro-Lite to fit the Yamaha YZ125, model years 2005–2017.

The YZ 125 rewards a fresh top and bottom end more than almost anything on the grid, and this Pro-Lite kit does both in one go. Forged piston, crankshaft, main bearings, seals and gaskets, matched to Yamaha's long-running 125 platform. A 125 lives at high rpm; ring grooves hammer out and big-ends run on borrowed time. Rebuilding the whole rotating assembly together means no worn part drags a new one down. Check bore taper before fitting the piston and pre-oil the big-end before the first kick.

§ 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.
