§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 54.00 E, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This E-size piston kit is for cylinders with maximum wear that are still within usable limits. It sits in the top-end and includes the piston, rings, pin, and circlips. The E-sizing is the largest available to take up the clearance in a worn bore. Accurate measurement with a dial bore gauge is critical before selecting this 54.00mm E-fitment. Regular top-end servicing prevents piston slap and maintains engine efficiency. Ensure the rings are correctly oriented and the circlips are fully seated. Check the squish gap to ensure optimal combustion and clearance on your bike.

§ 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.
