§ 02 / About this part

What it is

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

Refresh your top-end with this precision-machined kit. It sits in the cylinder bore to restore lost compression and engine response. These kits are often the preferred choice for maintaining OEM-level performance and reliability. The package contains the piston, rings, gudgeon pin, and circlips. Sizing is critical, so verify your cylinder grade before selection. Regular replacement prevents catastrophic failure and keeps the power delivery crisp. It is a standard service item for any high-strung four-stroke or two-stroke engine.

§ 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.
