§ 02 / About this part

What it is

The WOSSNER PISTON KIT - YAMAHA YZ450F 96.96MM PRO SERIES (13.50:1) 3R, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This Pro Series kit increases compression to 13.50:1 for sharper throttle response and improved torque. It is a direct fit for your YZ450F top-end. The forged construction handles the increased cylinder pressures of a race-tuned engine. Use this kit when your current piston reaches its hour limit to prevent power loss and blow-by. The 3-ring design ensures reliable sealing for both MX and cross-country use. Verify your cylinder bore condition and measure clearances before installation. Always use fresh circlips and lubricate the wrist pin during the 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.
