§ 02 / About this part

What it is

Vertex piston kit Ø66.40 A to fit the Honda CR250R, model years 1986–1994.

This A-size piston is the standard replacement for your engine. It is designed for cylinders that are new or within original factory tolerances. Swaps are essential for maintaining compression and preventing catastrophic failure. Check your bore diameter with a micrometer before fitting. Ensure the ring gaps are checked and the piston is oriented correctly. Lubricate the gudgeon pin and small-end bearing during the rebuild. This kit includes the rings, pin, and circlips.

§ 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.
