§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA Ø 54.25 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This cast piston sits in the top-end, designed to match factory performance and reliability. The 54.25mm (B) sizing is intended for cylinders that have been honed or have seen enough use to require a larger diameter for optimal clearance. You need to replace your piston kit at regular service intervals to prevent ring failure and maintain high compression. During assembly, check the ring end gap and ensure the piston is oriented correctly toward the exhaust port. This kit provides the piston, rings, gudgeon pin, and circlips for a professional top-end overhaul.

§ 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.
