§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA TOP END Ø 66.40 A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This replica top-end kit matches OEM part 54830007300. It sits in the cylinder bore and provides factory-standard performance and fitment. Replace this at regular intervals to maintain compression and engine efficiency. This is a size 'A' piston, intended for new or replated cylinders. Confirm your bore diameter with a micrometer before installation. The kit includes the piston, rings, gudgeon pin, and circlips. Ensure the ring end gap is checked and the piston is oriented correctly in the bore. Proper lubrication of the top-end is essential during the first start.

§ 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.
