§ 02 / About this part

What it is

Vertex piston kit Ø47.00 B to fit Gas Gas MC 85 17/14 (2022–2027); Gas Gas MC 85 19/16 (2021–2027); Husqvarna TC 85 17/14 (2014–2026); Husqvarna TC 85 19/16 (2014–2026); KTM SX 85 17/14 (2003–2026); KTM SX 85 19/16 (2003–2027); KTM XC85 (2008–2010).

This component sits in the top-end, engineered to restore compression and engine efficiency. The 47.00mm (B) sizing is designed for cylinders that require a slightly larger piston to maintain the correct clearance. Regular replacement is vital to prevent piston slap and ensure the longevity of your cylinder plating. Before installation, measure your bore and verify the ring end gap. Ensure the gudgeon pin is lubricated and the circlips are securely locked into their grooves. This kit includes the piston, rings, pin, and circlips for a complete workshop refresh of your bike.

§ 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.
