§ 02 / About this part

What it is

Vertex piston kit Ø54.00 D to fit the Honda CR125R, model years 2005–2007.

This component is the primary moving part within your engine's top-end. It needs replacing when the compression drops or when you reach the hour limit specified for your bike. Choosing the correct size increment is essential for maintaining the proper piston-to-wall clearance. This kit includes the rings, wrist pin, and circlips required for a standard service. During the install, lubricate the small-end bearing and the cylinder walls with fresh two-stroke oil. Double-check that the circlips are fully seated in their grooves before sliding the cylinder back over the assembly to prevent a failure.

§ 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.
