Piston group kit for Honda Dio scooters. The piston turns gas pressure into crankshaft motion, while the rings seal the cylinder and retain oil.
Replacement is needed if the piston is scored, compression is lost, or the cylinder has been rebored. The +0.50 mm size is an oversize (repair) size: it is used when the cylinder has been rebored for an oversize piston.
- Install new gaskets and seals.
