Piston ring -PIAGGIO- Vespa 200cc - Rally200, PX200, Cosa200 -

TIP: Always mount piston rings carefully. Piston rings made of cast material are only partially elastic and break relatively quickly.
Some pistons have trapezoidal profiled piston rings (so-called keystone rings), which only fit in one mounting position. If the ring is not free to move, please loosen it carefully and reinstall it turned 'upside down'.
