§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 76.00 A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Maintain peak performance in your high-revving four-stroke with this top-end kit. It sits at the heart of the engine, managing combustion pressure and oil control. Piston skirts and rings eventually wear down, causing oil consumption and lost compression. This A-size fitment is intended for fresh or replated cylinders to ensure factory-spec clearances. The kit provides the piston, rings, gudgeon pin, and circlips. Use a bore gauge to confirm your cylinder diameter before fitting. Always verify ring end gap and ensure correct orientation to avoid catastrophic failure during the first heat cycle.

§ 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.
