§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 53.95MM A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Standard A-grade at 53.95mm for a fresh or newly replated YZ 125 or YZ 125 X cylinder, cross-referencing OEM 1C3-11631-01-A0. A 125 revs hard and often; primary compression and ring seal fade well before anything sounds wrong. Fit a new top end on schedule rather than on symptoms. Piston, rings, gudgeon pin and circlips included. Hone the bore, wash it out properly, and set the crown arrow towards the exhaust. A routine job that heads off a rebore.

§ 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.
