Piaggio Vespa Piston Top (Dykes Ring) & Bottom Rings Standard PX125
This type of ring was first introduced on the Vespa PX125 Models. The piston ring is significantly different to other Vespa Piston Rings. Piston rings have to be slightly stretched out to allow fitment onto the piston. Piston rings made of cast material have only limited elasticity and break relatively easily. This was mainly used for the bottom ring on the P-range models.
