1974 Honda CB550K · Handlebar Switches Buying guide

Follow each side’s wiring route before removing a housing

These are separate black left and right assemblies. Their fitment wording and wiring arrangements differ, so compare each housing individually with your motorcycle rather than assuming the pair uses the same routing or connectors.

Plan the left-side wiring with the bar in place

The left assembly specifies wiring inside the handlebar. Inspect the existing lead route and bar openings before removing the housing, especially where a different bar has been fitted. Its CB400F eleven-wire note applies to that separate model and is not a CB550K connector specification.

Compare the right-hand controls instead of assuming an exact match

The right assembly’s fitment table names the 1974 CB550K, but its introductory note groups that year among bikes whose original housing lacks the added side OFF/ON switch. Compare the actual controls and connections before ordering; the conflicting wording does not support an unconditional original-control match.

Handlebar Switches questions

Do both assemblies route their wiring inside the bar?

No. The left assembly specifies internal handlebar wiring, while the right specifies external wiring. Check each side’s existing route and connector positions separately, particularly if the motorcycle has different handlebars or previously altered wiring.

Is the left switch specified for this year?

The detailed fitment list includes the 1974–75 CB550K, so 1974 is within that stated range. Compare the housing and internal wiring route with your installed parts; the wider introductory wording should not be used to assume fitment on every later year.

Can I rely on the right switch being identical to the original?

The listing includes 1974 CB550K fitment but gives conflicting notes about its side OFF/ON control. Check the control arrangement on your motorcycle and confirm any differences before purchase rather than treating the direct-fit wording as an exact-match guarantee.

Not sure which part you need?
