The Wossner 8125DA piston kit is designed for Honda CR125 motorcycles from 1988 to 1989. Manufactured in Germany using forged construction, this piston offers increased durability and efficient heat dissipation. The elliptical design ensures uniform bearing surface under high-temperature expansion, minimising localised stress and preventing piston deformation. The kit includes all required components for proper installation and performance restoration.
