This tachometer is a reproduction of the original RSM 3003/13 3:1 drive ratio black-faced instrument.
This spare is applicable to BSA A50 and A65 models from 1970-1972.

Specific 3:1 drive ratio for BSA twins fitment. This reproduction gauge is 1/4″ taller than the original Smith’s tachometer.

The tachometer monitors engine speed and is driven by a cable.

The tachometer is mounted to a bracket on the top yoke of the fork, usually fitted into a rubber cup. Due to the extra height of the unit, it will protrude above the rubber cup when fitted.
