BSA Cable — tachometer drive
Tachometer drive cable, catalog part 19-9099, listed under electrical equipment.
This is a tachometer drive cable, listed in the catalog under part number 19-9099. The listing places it in the electrical equipment section of the parts book, which is where these instrument cables usually get filed alongside the wiring and switchgear even though the cable itself is a mechanical part, not electrical.

A tach drive cable runs from the drive unit on the engine or gearbox up to the tachometer head, spinning the instrument so you get an accurate rev reading. If yours is fraying, kinked, or the tach needle is jumping or reading wrong even though the tach itself checks out, the cable is a common culprit.
Our records show this number appearing across catalog entries from 1971 to 1972, but we don't have a firm read on which specific model that ties to beyond the manufacturer listing. Give us a call and we'll confirm fitment before you order.
