Brand new 12V CDI ignition coil to fit:
Honda CB 650 Z-C (S.O.H.C.) (1979-1982).
Honda CB 650 CA-CB Custom (S.O.H.C.) (1980-1981).
Honda CB 650 SC Custom (S.O.H.C.) (1982-1984).
Honda CB 650 SC Nighthawk (S.O.H.C.) (1982-1985).
This coil has been manufactured to be an upgrade on either of the coils 30500-422-003, 30500-422-013 or 30506-MA6-003 on a CB650 for the years and models shown above. This is a high quality upgraded coil and you'll no longer need to run a ballast resistor in the system. We don't sell the 2 ohm primary replacement anymore as it's inferior to running these coils and bypassing the resistor.
The Ignition coil is 12V, has 100mm mounting points and 2 spade connectors, with 2 HT leads.
