Replace your worn segments with a precise and reliable set designed for the top-end: the WÖSSNER 89.5mm Piston Ring Set is a kit intended for vintage motorcycles and custom builds where the size Ø89.5 mm is required. Designed to ensure sealing between the piston and cylinder, this set helps restore compression and reduce smoke related to the wear of original segments.
Ideal for restoration enthusiasts and builders looking for a clean installation and mounting sets that conform to the stated dimensions. Before installation, check the condition of the cylinder, the honing, and the axial/conical play recommended by the manufacturer. In case of doubt, verify compatibility with your engine's piston size to ensure an optimal fit.
