§ 02 / About this part

What it is

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

This top-end kit is a vital maintenance component for any performance bike. It replaces the piston and rings to restore lost compression and ensure reliable power delivery. Regular service intervals are critical to prevent piston fatigue and skirt breakage. This kit includes the piston, rings, gudgeon pin, and circlips. Check your cylinder bore for wear and ovality before fitting. Ensure the ring gaps are correctly aligned with the locating pins in the piston grooves. Always use fresh gaskets and a new small-end bearing when performing a top-end rebuild.

§ 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.
