This is the correct speedometer drive unit for the 1967-1970 Triumph TR6, T120, and T150 models in the 1.25:1 ratio and is also correct fitment for 1968-1970 BSA A75. Can also be used on BSA A65 and Norton Commando models with 11/16″ diameter axle, although a slightly larger gap will be visible when installed on the hub. Must be paired with 150 mph speedometer.
The speedometer drive gearbox replaces the original Smith’s BG5330/168 1.25:1 reversing drive unit that is bored to accept a 3/4″ rear wheel spindle. Quality reproduction part from Emgo.
The speedometer drive gearbox is fitted over the rear wheel spindle onto the hub and turns with the wheel. The internal gear drives the cable to the speedometer.
For the best available quality we recommend the LF Harris produced speedo drive, see below.
