Piston rings for the Honda DIO 34 scooter, +0.50 mm oversize. The rings seal the piston in the cylinder, maintaining compression and keeping oil out of the combustion chamber. Manufacturer: TATA. Country of origin: China.
Consider replacing them if compression drops, acceleration is sluggish, the exhaust is smoky, or oil consumption is high. The ring size must match the size of the piston and cylinder.
