With this piston, you restore the compression of your engine block during an overhaul.
The piston works together with the piston rings to seal the compression. A new piston of the correct size ensures a proper seal again.
This part is suitable for the Sachs and Hercules (with a 38mm bore). Brand: Parmakit.
Choose the piston size that fits your cylinder and always install new piston rings and a new piston pin clip.
