Beautifully hand made in Wales. Black billet machined aluminum cases with screw on bezel. We now offer the wider flange bezels and brackets for older British Motorcycles with nacelles (see accessories). The chronometric gauges are the same diameter as the originals with stainless steel mounting studs located at 6 and 12 o’clock. The wiring harness is disguised as the light bulb wire complete with woven cloth covering and a solid brass knurled thumb screw fitting. A threaded dummy fitting is available that screws in the bottom (comes with removable plug)) for those wanting to really replicate the look of a stock gauge allowing a section of speedo or tach cable to be attached and terminate elsewhere in the bike. Digital odometer/trip meter and built in LED lighting. Please note: 12 volt only positive or negative ground so you must have a 12v battery. You may need to use the HT sensor & amplifier for the chronometric tachometer on motorcycles with magnetos. The Smiths Digital Chronometric uses the same graphics and typeface as the originals but now is an updated version of the early units used on classic British Motorcycles. Please check the accessories page or call to see what type of sender will drive your new updated speedometer. Chronometric speedometers are now available in 80, 120, and 140 mph and the equivalent in KPH. Chronometric tachometers are available in both 8,000 and 10,000 rpm.
