§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 47.94MM A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit serves as a direct replacement for OEM part 13001-1497. It is a critical component for your rebuild, sitting inside the cylinder to maintain primary compression. Periodic replacement is vital for preventing skirt failure and bore damage on race-tuned engines. The kit includes the rings, gudgeon pin, and circlips. Measure your bore accurately to ensure this graded fitment is correct for your current cylinder state. During installation, ensure the rings are seated correctly in the lands. Lubricate the pin and small-end bearing thoroughly before closing the engine.

§ 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.
