1974 Honda CB360G · Piston Ring Sets Buying guide
Three rings in a package describe one piston’s ring set. Bore size and the number of pistons being serviced determine the order; the motorcycle’s year alone cannot confirm either after earlier engine repairs.
The set contains a top compression ring, second ring and oil-control ring for one piston. Reference 13011-369-305 identifies the standard-size application. For both pistons in the CB360G twin, order two sets rather than interpreting “set of three” as an engine-wide quantity.
A previous rebore changes the ring requirement even when the engine still looks original externally. Match the piston marking and measured bore, and use the appropriate Honda service specifications for inspection and assembly. Standard rings should not be selected merely because the bike is a 1974 model.
One pack supplies the three rings for one piston. Two packs are required when both standard-size pistons are being re-ringed; it is not a three-piston or full-engine package.
These are specified for standard 67 mm bore applications. If the piston or cylinder is oversize, identify the actual size and select the corresponding rings instead.
Have the bore and piston measured against Honda’s service limits before ordering. If their condition calls for further engine work, standard replacement rings alone are not an established repair.
