1975 Honda CB550K Left Handlebar Switch Assembly

One handlebar switch carries the 1975 Honda CB550K tag: the black left-hand assembly on the clutch side. It stands in for two Honda numbers, and the listing notes that its wiring runs inside the handlebar, which affects how it is fitted.

Restoring the controls

Match the replacement to the clutch side, housing finish and existing wire route. This listing uses internal handlebar wiring, so a motorcycle with changed bars or external wiring needs closer comparison before ordering the assembly.

Internal wiring

The listing specifies wiring routed inside the handlebar. Compare that arrangement with your current bar, its wire openings and harness connectors. A replacement bar or earlier rewiring may change the required arrangement, so check the supplied instructions before choosing this internally wired assembly.

Identify the right-hand assembly separately

This category’s verified 1975 application is the left switch. A right-hand assembly should be checked separately against its own year application, connector and housing. Contact the store with photos and the existing reference if the brake-side controls also need replacing.

Common questions

Does the left switch fit the 1975 CB550K?

The black left switch references Honda 35200-374-671 and 35200-390-671 and lists CB550K models from 1974 to 1975. Compare the internal wiring route and connectors with the installed controls before selecting it.

Is the right-hand switch available?

A right-hand assembly is not included in this verified 1975 category. Compare its housing and connector separately, and provide the store with the existing part reference or photos rather than assuming the left listing covers both sides.

What colour is the switch housing?

The listing describes a black, clutch-side assembly with wiring routed inside the handlebar. Compare its finish and wire arrangement with the controls currently fitted, particularly if the bars have been changed.
