§ 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 — 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.
