§ 02 / About this part

What it is

The WOSSNER PISTON KIT PRO YZ250F 05-07/EC250F 10-15 76.97 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston kit refreshes your top-end for improved reliability and performance. It replaces the factory unit to prevent power loss from ring wear. This B-size piston is slightly larger to compensate for minor cylinder wear and restore optimal clearances. The kit includes the piston, rings, gudgeon pin, and circlips. Forged construction provides the strength needed for competitive use. Check ring end gaps in the bore before fitting. Ensure the cylinder is properly honed for ring seating. Align the piston arrow with the exhaust port to avoid valve interference.

§ 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.
