Speedometer gearbox
Speedometer gearbox for the rear wheel, drives the speedo cable off the hub on quickly-detachable wheel setups.
This is the speedometer gearbox that mounts at the rear wheel and drives the speedo cable off the hub. It's a gear-drive unit, not a cable end fitting - it takes rotation off the wheel and converts it to the ratio the speedometer head needs to read correctly. The catalog lists it under the rear wheel figures, including the quickly-detachable wheel setup, so this is where it lives on bikes fitted with that hub arrangement.

The older book number for this part is D373, which you may see printed in earlier parts lists - same physical piece as 60-0373.
Our records show this part appearing across rear wheel figures from the mid-60s into the mid-70s. If you're trying to match this to a specific model or year, check what's stamped or listed on your own hub and give us a call to confirm before ordering - the gearbox has to match the hub type and the speedometer ratio it's paired with.
