§ 02 / About this part

What it is

The VERTEX PISTON KIT POLINI, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This assembly restores compression and engine efficiency. It sits within the cylinder bore and handles the combustion forces of your bike. The piston requires replacement at set hour intervals or when blow-by reduces performance. This set includes the rings, gudgeon pin, and circlips for a complete refresh. Check your cylinder bore size against the piston grade before installation. Ensure the ring end gap is within tolerance for your specific stroke. Proper lubrication during assembly prevents initial scuffing. It is a direct replacement for your worn OEM component.

§ 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.
