§ 02 / About this part

What it is

The VERTEX PISTON KIT PRO REPLICA Ø 77.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit restores the seal in your cylinder to maintain compression and power. It sits inside the bore and requires replacement as the rings and skirts wear through use. Use the B size to account for minor bore wear and maintain the correct piston-to-wall clearance. This assembly matches OEM part 12110-49830 for a direct swap. The package includes the piston, rings, gudgeon pin, and circlips. Always verify your ring end gap before fitting. Ensure the arrow on the crown points toward the exhaust port. Regular maintenance ensures your bike performs at its peak.

§ 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.
