§ 02 / About this part

What it is

The WOSSNER PISTON KIT FORGED STEEL PERFORMANCE REPLACEMENT / YAMAHA / SIZE +0,50, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged assembly is designed for cylinders requiring a significant rebore. It increases displacement or cleans up heavy scoring within the engine. Forged construction handles the increased loads of a performance build. You must have your cylinder bored and honed to match this specific diameter. Check ring end gaps carefully before final assembly. Ensure the wrist pin clips are fully seated in their grooves. Lubricate the small-end bearing during the build. This kit provides the necessary components for a full engine refresh. Follow a controlled heat-cycle process to bed the rings into the new bore surface.

§ 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.
