§ 02 / About this part

What it is

The WOSSNER PISTON KIT FORGED STEEL PERFORMANCE REPLACEMENT / YAMAHA / SIZE +0,01, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This +0.01mm forged piston kit is designed for Yamaha engines. The slight oversize provides a tighter seal in cylinders that have seen moderate use. Forged pistons are preferred for their resistance to cracking under high combustion pressures. This kit contains the piston, rings, pin, and clips. Accurate measurement of your bore is critical to ensure the +0.01mm sizing is appropriate for your bike. Replacing the piston at recommended intervals prevents catastrophic failure and maintains peak engine performance. Always use fresh gaskets when reassembling the top-end.

§ 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.
