Tachometer cable (26½ in. long)
A 26½ inch tachometer drive cable listed under 60-0648, connecting the tach head to its drive unit.
This is the tachometer drive cable, 26½ inches long, listed in the parts books under 60-0648 (the older stock number D648 shows up on earlier documentation for the same cable). It runs from the tach head down to the drive unit at the engine, spinning the tach needle off engine speed rather than wheel speed the way a speedo cable does.

It shows up in the SPEEDOMETER AND TACHOMETER section of the parts books, alongside the speedo cable and the two instrument heads, across catalog entries spanning 1967 to 1974. If your bike came with a tach, this cable is a wear item worth checking for fraying at the ends or a cracked outer casing, since a worn cable is a common cause of a jumpy or dead tach needle.
We don't have more detail on this one beyond the length and where it sits in the instrument cluster, so if you're not sure your bike takes a 26½ inch cable, give us a call and we'll confirm before you order.
