Piston rings seal the piston in the cylinder: they maintain compression, scrape off excess oil and carry heat away. Country: China. Rings for 4T 50 scooters, various versions.
They should be replaced if compression drops, cold starting is hard, there is smoke from the muffler, or oil is being consumed. The size is given in the name; if the cylinder has been bored, oversize rings are needed. Can't identify the part you need? Call us and we will pick it by the make and model of your vehicle.
