§ 02 / About this part

What it is

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

This replica kit provides an OEM-standard refresh for 125cc engines. The B-size is the standard choice for cylinders that have completed their first few race seasons and show minor wear. It restores the factory-spec compression and throttle response. This top-end kit includes the piston, rings, gudgeon pin, and circlips. Small-bore two-strokes require frequent piston changes to avoid catastrophic failure. Ensure the piston ring is seated correctly over the locating pin before sliding the cylinder down. Check your squish gap with solder to confirm the engine is running at peak efficiency.

§ 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.
