WÖSSNER Segment Ø54.25 mm (Manufacturer part number: RSB5425) — replacement part dedicated to engine restoration of Cross machines. Manufactured by WÖSSNER, a German specialist in engine components for 2 and 4-stroke engines, this segment is designed to fit the brand's pistons and replace worn elements during a rebuild.
Ideal for amateur mechanics as well as professional workshops, this segment retains the original dimensions to ensure proper contact with the cylinder wall and effective wear compensation. It integrates into a disassembly/check operation of the piston and cylinder, to restore a compliant segment clearance and limit compression losses due to wear.
