§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 53.94MM A1, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit provides precise maintenance for your bike. It replaces the worn factory unit to restore compression and throttle response. The graded sizing allows you to match the piston to your cylinder's specific wear profile. It sits within the bore, secured to the connecting rod. Rebuilds are necessary at set hour intervals to avoid skirt fatigue. The kit comes complete with rings, pin, and clips. Always verify the ring gap in the bore before fitting. Position the circlip gaps away from the removal notches. This kit matches factory specifications for a direct drop-in fit.

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.
