§ 02 / About this part

What it is

Vertex piston kit Ø39.50 A to fit Gas Gas MC450F (2021–2023); Gas Gas MC50 (2021–2027); Husqvarna TC50 (2017–2027); KTM SX 50 MINI (2008–2023); KTM SX 50 MINI ADVENTURE (2007–2008); KTM SX50 (2006–2026).

This A-size kit is for 50cc engines with new or standard-spec bores. It is the heart of the top-end, responsible for maintaining the compression needed for small-capacity performance. These engines run at high RPM, making regular piston changes essential to prevent ring sticking or skirt failure. Check the bore for any scoring before fitting this 39.50mm kit. Lubricate the small-end bearing and gudgeon pin thoroughly during assembly. The kit includes the piston, rings, pin, and circlips. Ensure the rings are correctly oriented on the locating pins before sliding the cylinder down.

§ 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.
