The 150 mph black-faced speedometer is a replica of the Smith’s SSM 5007/00 instrument, and is compatible with the 1.25:1 speedometer drive gearbox. The black-faced tachometer is a replica of the Smith’s RSM 3003/13 and is in a 4:1 ratio condition.

Suitable for 1970-1974 Triumph 650 and 750 models. These will also fit 1967-69 Triumph 500 & 650 twins, though they technically the would have originally had grey face instruments fitted.

The speedometer is a Smith’s SSM 5007/00 replica. Must be paired with a 1.25:1 or 15/12 speedometer drive gearbox. The tachometer is a Smith’s RSM 3003/13 replica that is a 4:1 ratio. Note that the replicas are 1/4″ taller than the original Smith’s instruments.

The speedometer is driven by the speedometer drive gearbox on the rear wheel that is coupled to the instrument with a rotating inner cable. The tachometer is driven by a tachometer drive gearbox mounted on the drive-side crankcase that is coupled to the instrument with a rotating inner cable.

Both instruments are hard-mounted to a bracket mounted on the top fork yoke of the 1970 models. The 1971-1974 models use rubber instrument cups and brackets to mount the instruments.
