1981 Honda CB900F Supersport · Handlebar Switches Buying guide
Identify the faulty function before replacing a whole switch housing. Check the controls, connectors and wiring using the CB900F diagram, then compare the left or right assembly. Both replacement switches route their wiring outside the handlebar.
The black left-side assembly covers turn signals, horn and lighting controls and cites references 35200-460-671, 35200-425-672 and 35200-445-671. Use those details with the wiring diagram to compare the fitted control. A previous switch or loom change should be checked before replacement.
Changed bars can stretch or trap the switch loom. Compare the external route and connector positions, leave the required movement at the steering head and keep wires clear of pinch points. Use the switch instructions and wiring diagram rather than joining wires only by color.
No. Check the affected lamp or horn circuit, its power supply and connections as well as the switch contacts. Use the wiring diagram and continuity checks to identify the fault before replacing the complete left assembly.
Both listings specify wiring outside the handlebar. Compare the fitted bars and required external route before ordering. Do not force the loom through an unsuitable opening or let it pull tight at steering lock.
No. Check each terminal function and the required switch reference against the correct diagram and replacement instructions. Modified wiring can place a different circuit in a similar connector.
