§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 46.97MM C, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This C-size kit replaces OEM part 13001-1500 and is sized for cylinders that have seen moderate use. It sits in the top-end, providing a precise fit to compensate for bore expansion. Moving to a C-size prevents the piston from rocking, which reduces wear on the cylinder plating. Measure your bore accurately to confirm this is the correct increment. Check that the ring end gaps meet the workshop manual specifications. Ensure the arrow on the crown points toward the exhaust port to avoid port snagging.

§ 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.
