§ 02 / About this part

What it is

Vertex piston kit Ø54.00 A to fit the Suzuki RM125, model years 1989–1999.

This kit sits at the heart of your 125cc top-end. Two-stroke pistons are high-wear consumables that require frequent replacement to maintain peak power and prevent skirt failure. Choosing the correct letter size (A through D) allows you to compensate for cylinder bore wear, ensuring the piston-to-wall clearance stays within workshop limits. A fresh piston restores the primary compression needed for crisp throttle response. The kit includes the rings, gudgeon pin, and circlips. Always install a new small-end bearing when refreshing the top-end to ensure the longevity of 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.
