§ 02 / About this part

What it is

The WOSSNER PISTON KIT FORGED STEEL PERFORMANCE REPLACEMENT / YAMAHA / SIZE +0,02, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore compression and reliability to your top-end with this graded forged assembly. These increments allow for precise clearance matching in cylinders with minor wear or specific honing requirements. Forged construction offers superior thermal stability compared to cast alternatives during high-load race conditions. This kit includes the rings, gudgeon pin, and circlips. Measure your cylinder bore accurately to ensure the correct clearance for this specific size. Always verify ring end gap in the bore before final assembly. Position the crown arrow toward the exhaust port during installation. Regular top-end intervals prevent skirt fatigue.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
