Service the mechanical speedometer on your 1984 CB650SC by matching the black replacement cable and its 44830-ME5-405 reference. The separate plug closes the retained wheel-drive opening when that cable is removed. Choose between restoring cable operation and modifying the instrument system before ordering.
Match the cable or close the retained unused drive
The cable has an explicit late-CB650SC application. The approximately 15mm outside-diameter, 22mm-long plug closes the retained original wheel-drive opening after cable removal. Its purpose differs from renewing a cable for a working mechanical speedometer.
The black cable is listed for the 1983–85 CB650SC and replaces 44830-ME5-405. Compare the existing ends and routing before ordering. A changed handlebar, instrument or wheel-drive arrangement needs extra checking because the original model application cannot describe the details of a custom installation.
Plan the closure separately from cable service
The plug helps keep the original wheel-drive gear clean by closing its unused cable opening. Select it after removing the mechanical speedometer cable, with the original drive retained. Compare the approximately 15mm outside diameter, 22mm length and retainer; electronic conversion equipment is not included.
Buying questions
What should I check before treating the cable installation as finished?
Route the cable in broad curves with enough slack for steering and fully engage the inner cable at both ends. Confirm smooth speedometer operation without needle bounce. A changed instrument position still needs its own connection and routed-length check.
When should I choose the wheel-drive plug?
Choose it when removing the mechanical speedometer cable while retaining the original wheel drive. Check the approximately 15mm outside diameter and 22mm length against the intended opening. It supplies a closure, not a replacement cable, gear or complete electronic speedometer conversion.
Can I assume the cable suits a custom instrument layout?
Check the new instrument connection, fitted wheel drive and intended route first. The cable’s listed CB650SC application supports the original-type repair; a custom layout needs its own connection and routing assessment before the order is placed.
