§ 02 / About this part

What it is

The VERTEX PISTON KIT TOP END Ø 54.00 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-size kit is designed for 125cc cylinders that have moved past their initial break-in phase. It accounts for minor bore wear to maintain the optimal piston-to-wall clearance. A fresh piston is essential for keeping your bike at peak performance and preventing mechanical failure. The kit comes with the piston, rings, gudgeon pin, and circlips. Measure your bore accurately to ensure the B-size is the correct fitment. During installation, verify that the circlips are fully seated in their grooves. Proper heat cycles are required to bed in the new rings for maximum durability.

§ 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.
