It has a rigid rear suspension, and a leading-link front suspension. Some models include a sprung seat-post. The engine and drive-train are cleanly enclosed, similar to Piaggio's scooters. The Ciao uses a belt drive, unlike most other mopeds which are chain driven. Some models have an automatic continuously variable transmission. Braking is by front and rear drums. Power for the lamps, horn, and ignition is from a magneto; there is no battery. However, models with turning signal lights were equipped with a 6-volt battery for the blinkers to function. On newer models, the plastic fuel cap also serves as a measuring cup for the 2% oil-fuel mixture.
In some countries, such as Canada in the 1970s, these mopeds were branded as the Vespa Ciao.
Model variants include:
- Ciao SC (round saddle rack, saddle and suspension seatpost; light at the rear fender; racks are not removable; chrome fenders)
- Ciao L (square saddle rack, and only semi-suspension; light at the rear fender; racks removable)
- Ciao P (square saddle rack, and only semi-suspension; light at the rear rack; racks removable)
