Norton Cable, Tachometer Drive
Tachometer drive cable for the Norton Commando twin, part number 06-1118.
This is the tachometer drive cable, part number 06-1118, and it's a Norton part, not a Triumph one — it's set up for the Commando twin. The tach cable runs from the drive unit up to the tachometer head itself, so the needle on your tach follows engine speed the way it's supposed to. If yours has gone stiff, kinked, or the needle's jumping around, the cable itself is usually the culprit before you start suspecting the drive or the instrument.

The catalog groups this with the speedometer and tachometer drive cables and even the police horn fitments, which tells you it lives in that instrument-drive cluster rather than anywhere in the electrics proper, even though it's filed under electrical in some listings. It shows up in the parts book for the 1975 model year in our records.
Check the fitting on your end — the connector style matters for a clean swap — before you order, and give us a call if you're not sure which cable your bike takes.
