§ 02 / About this part

What it is

The WOSSNER PISTON KIT FORGED STEEL PERFORMANCE REPLACEMENT / YAMAHA / SIZE BANSHEE: +1,00 / RD: +1,00, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore compression to your top-end with this oversize forged assembly. These sizes are designed for cylinders requiring a re-bore or a fresh sleeve to clear surface damage or significant wear. Forged construction offers superior thermal stability compared to cast alternatives during high-load race conditions. This kit includes the rings, gudgeon pin, and circlips. Ensure your machinist has these parts in hand before boring the cylinder to achieve the exact clearance required. Always verify ring end gap in the bore before final assembly. Position the crown arrow toward the exhaust port during installation.

§ 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.
