§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA Ø 54.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component is a direct cross-reference for OEM part 1C3-11631-03-D0. It sits in the top-end, providing a factory-spec fit for your engine rebuild. The 54.00mm (B) sizing is ideal for cylinders that have moved past their initial (A) tolerance. Regular replacement of the piston and rings is essential to maintain peak power and prevent damage to the cylinder bore. During installation, verify the ring end gap and ensure the circlips are fully seated in the grooves. This kit includes the piston, rings, gudgeon pin, and clips for a professional refresh.

§ 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.
