§ 02 / About this part

What it is

Vertex piston kit Ø48.50 A to fit the Kawasaki KX 85 17/14, model years 2001–2006; Kawasaki KX 85 I 17/14, model years 2007–2013; and Kawasaki KX 85 II 19/16, model years 2007–2013.

This assembly is the core of your engine rebuild. It sits within the cylinder bore to maintain compression and power delivery. Regular swaps are essential to prevent skirt fatigue or ring failure. This A-grade sizing is intended for new cylinders or fresh replates. Always verify your bore diameter with a dial bore gauge before selection to ensure the correct clearance. Check your ring gap and ensure circlips are seated correctly in the grooves. Follow OEM torque settings for the head and base gaskets to finish the job.

§ 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.
