§ 02 / About this part

What it is

The WOSSNER REPLACEMENT 4-STROKE PISTON RING SET, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Maintain compression and oil control during your top-end rebuild. These rings sit in the piston grooves to seal the combustion chamber and scrape excess oil from the bore. Over time, heat and friction reduce tension, leading to blow-by and power loss. Always check your end gap in the cylinder before installation to ensure proper thermal expansion. This set replaces worn components to restore factory performance levels. Match the SKU to your specific bore size for an exact fit. Clean the ring grooves thoroughly to prevent carbon build-up from sticking the new rings.

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.
