§ 02 / About this part

What it is

Vertex piston kit Ø39.50 A to fit the Beta RK 6, model year 1997, and Beta ST 50, model years 1996–1997.

This A-size piston is the standard fitment for your engine. It is intended for cylinders with minimal wear or those that have been recently replated. Regular replacement is a key part of maintaining performance on small-displacement bikes. Measure your bore to ensure the A-size provides the correct clearance. Check the ring gap and ensure the piston arrow points toward the exhaust port. This kit includes the rings, gudgeon pin, and circlips for a complete 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.
