§ 02 / About this part

What it is

The PROX PISTON KIT YZF450 23- B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-sized kit is designed for the updated YZF450 engine. It sits in the top-end and manages high-RPM combustion cycles. As the cylinder bore wears slightly over time, moving to a B-size piston maintains the correct clearance. Replacing the piston at recommended intervals prevents skirt fatigue and loss of compression. The kit comes with the piston, rings, gudgeon pin, and circlips. Check your valve clearances while the top-end is apart. Ensure the ring gaps are correctly aligned according to the workshop manual.

§ 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.
