§ 02 / About this part

What it is

The WOSSNER PSTN KT YAM YZ450F STD A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged top-end kit is essential for maintaining the performance of your YZ450F. The piston sits at the heart of the combustion process and wears over time due to friction and heat. Standard A sizing is designed for cylinders that are still within original factory dimensions. The kit includes the piston, rings, gudgeon pin, and circlips. Regular replacement is the best way to avoid expensive engine damage. Verify the ring gap and ensure the circlips are fully seated in their grooves. Lubricate the small-end assembly during the build to prevent initial dry-start wear. Clean the bore thoroughly before installation.

§ 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.
