SIP 2.0 Speedometer & rev counter unit for Vespa PX scooters up to 1984. 

The unit is run on 12V AC/DC and requires no battery in the electrical system of your scooter. It is also fully compatible with Vespatronic and Parmakit performance ignition systems. To adjust and scroll through the functions on the electronic display a small button is included, which can be easily and inconspicuously located beneath the scooters existing light switch. A snazzy gimmick: During the ignition sequence the speedometer unit carries out a complete function check, similar to current high-tech GP racing machines.
A new feature of the 2.0 version is the choice between an analogue speedometer or rev counter. The speedometer needle can be used to display either speed or rpm. During longer trips you can also record the total time of your journey and the average speeds for both daily stages and the whole tour, which can be set up individually. The total number of kilometres travelled, recorded by your original speedometer unit, can also be transferred to the km value displayed. In combination with the SIP fast flow fuel tap, with fuel reserve sensor, all Vespa models can now benefit from a fuel level warning function. To indicate the ebbing level in your fuel tank 'FUEL' starts to blink on the electronic display. In addition, it also improves the voltage regulation of your complete electrical system.

Rev counter
Digital displayed speed
