§ 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 cast piston is a direct cross-reference for OEM part 12101-36821. It sits in the top-end, designed to match the original factory specifications for fit and performance. The (B) sizing is slightly larger than standard, making it suitable for cylinders with minor wear. Periodic replacement prevents ring failure and maintains the integrity of your cylinder walls. Before fitting, 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 complete top-end 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.
