§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA Ø 66.40 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component is a direct replacement for OEM part 12101-37893. It sits in the top-end, providing a reliable seal and efficient power transfer. The 66.40mm (B) sizing is intended for cylinders that have seen use and require a tighter skirt clearance than an (A) piston provides. Regular top-end maintenance is vital to prevent blow-by and ensure consistent engine performance. During installation, verify the ring end gap and ensure the circlips are securely seated. This kit includes the piston, rings, gudgeon pin, and clips for a professional engine 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.
