The due to their external design also called shell speedometer were installed in many old Vespa's from the 1960's. They are available in various designs, i.e. with different scaling for the speed (100km / h - 110km / h - 120km / h) and different designs of the dials (red - blue - black and with or without Piaggio logo).
In principle, the speedometers can be interchanged, ie a 120km / h speedometer can also be used in a handlebar that was originally intended only for a copy of 100km / h. However, there are differences in the mounting technology. Round handlebar models have a different holder than the trapezoidal handlebars. However, the holders can usually be changed.
TIP:
Piaggio no longer manufactures speedometers but also buys them in India. The quality of an expensive, supposedly original Piaggio speedo is therefore identical to a much cheaper repro speedo.
Note: Without bulbs for the speedometer illumination (see 'Accessories').
