Wossner is a German manufacturer of high quality forged and graphited pistons.

The obsessive attention to detail and the entirely proprietary production process have made it the best piston available on the market over time.

Wossner pistons are available in a wide range of models and sizes.

Wossner pistons are supplied complete with bands, stops and piston pins.

The assembly must be carried out by specialized personnel, following the instructions of the motorcycle manufacturer and in any case after checking the adaptability and the correct compression ratio BEFORE the installation.
