§ 02 / About this part

What it is

Vertex piston kit to fit the Yamaha WR450F, model years 2019–2020, and Yamaha YZ450F, model years 2018–2019.

This top-end assembly sits at the heart of your engine. It converts combustion into mechanical drive within the cylinder bore. Regular replacement is vital to maintain compression and prevent skirt failure. Most race-spec bikes require a fresh kit every 20 to 50 hours. This kit includes the rings, gudgeon pin, and circlips. Verify your cylinder size for the correct A, B, or C fitment before installation. Always check ring end gaps and ensure circlips are seated correctly in the grooves. It serves as a direct technical alternative to OEM components for your next top-end 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.
