§ 02 / About this part

What it is

The VERTEX PISTON KIT PRO REPLICA Ø 48.50 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Maintain the reliability and power of your engine with this top-end kit. It sits within the cylinder bore and handles the primary thermal and mechanical loads. Over time, piston skirts wear and ring tension drops, leading to blow-by and reduced power. This B-size fitment is designed for cylinders with minor wear to maintain precise tolerances. The kit includes the piston, rings, gudgeon pin, and circlips. Measure your bore with a gauge before installation. Always check ring end gap and ensure the piston arrow points toward the exhaust port during your 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.
