§ 02 / About this part

What it is

The VERTEX PISTON KIT YZ450F 23-/WR450F 2, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This top-end component is critical for maintaining the tight tolerances required by modern four-stroke engines. Over time, heat cycles and high RPM wear the skirt and rings, leading to lost compression and potential cylinder damage. This kit replaces the factory unit to restore performance levels. Ensure you measure your bore accurately to select the correct size. The kit includes the piston, rings, gudgeon pin, and circlips. Proper break-in is essential to seat the rings against the cylinder wall. It is a direct fit for your rebuild.

§ 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.
