§ 02 / About this part

What it is

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

This kit provides the essential components for a top-end refresh on your four-stroke. It sits at the heart of the engine, managing compression and combustion. Over time, piston skirts wear and ring tension drops, leading to blow-by and power loss. This kit includes the piston, rings, wrist pin, and circlips. Ensure you measure your cylinder bore for the correct size grade before installation. Proper break-in is essential to seat the rings against the cylinder wall. It is a direct replacement for the stock component, maintaining factory performance levels for your YZ450F or WR450F.

§ 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.
