New Tachometers and Speedometers

572 Series

Now Available: A new range of speedometers and tachometers to replace the out-of-production Smiths and Veglia gauges for popular Triumph applications. These units differ only slightly in appearance from the originals, but have the advantage of modern internal design and good availability, with no exchange unit or core charge required.

At present, they are only available in the ratios listed, but no doubt others will be added in the future. In the meantime, with use of the correct drive gearbox, these can be used on virtually all Triumph models using the "large" (3.14" O.D.) gauges, except for certain ones which drive instruments directly off the engine or transmission since they have a different ratio.

It should be noted that these instruments have no manufacturer's name on the face, which is similar to original design as used on late model Smiths (black face with white numerals and needle) and that standard cables fit on as original with no adaptors required. They do require a different bulbholder assembly than original, BCS # 572-10, which must be lubed with rubber lubricant and installed very carefully due to tight fit to keep water out. Bulb for this holder is BCS #392-504.

The stud mounted instruments will bolt onto stock instrument "brackets" as original, using the original nuts (21-0778). The instruments without studs are best for rubber cup mounting as used on most Triumph models 1971 and later.

When ordering, if possible quote numbers of the old instrument or speedo drive unit; if the old speedometer is not a 1000 rpm per mile unit, a replacement rear drive of the correct ratio may be required.

For comparison purposes, sizes are as follows:

BCS Replacement instruments: O.D. 3.14"; Height 2.15"
Veglia Instruments: O.D. 3.14"; Height 2.23"
Smiths Instruments: O.D. 3.14"; Height 1.78"

At present, we do not have replacement instruments suitable for BSA or Norton models, with the exception of the 572-11/A tachometers which will fit all Commando 850 models, but we will announce additions to this range as available.
