Frequently Asked Questions
Is 12-0065 a complete Honda CB ignition switch?
No. It is the base cover only. Ignition switch 12-0051 is sold separately.
Will switch base cover 12-0065 fit any original Honda ignition switch?
It is designed for ignition switch 12-0051. Match the cover to that switch rather than assuming compatibility with every original switch used across the compatible motorcycle years.
