§ 02 / About this part

What it is

The VERTEX PISTON KIT BB YZ250F 19-/WR250, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit is for big-bore conversions on the YZ250F and WR250F platforms. It sits in the top-end and provides more grunt across the rev range. Big-bore pistons have different weights and thermal properties than OEM parts. This kit includes the piston, rings, pin, and clips. Ensure your cylinder has been prepared specifically for this big-bore size. Check the squish clearance during assembly to prevent detonation. Use a fresh air filter to keep debris out of the new top-end. Follow the recommended torque sequence for the head bolts.

§ 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.
