§ 02 / About this part

What it is

The WOSSNER PISTON KIT PRO RR250 05-07/15-19/EXC250 01-06 74.9, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston kit refreshes the top-end of your two-stroke engine. It sits within the cylinder to manage port timing and compression. Replace this part when ring tension drops or at scheduled race intervals to prevent piston slap. The kit includes the piston, rings, gudgeon pin, and circlips. Forged pistons offer superior strength for high-RPM use. Check the ring end gap and ensure the ring pegs are correctly positioned. Orient the piston with the arrow facing the exhaust port to avoid snagging the rings on the ports.

§ 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.
