The Piaggio Ciao (ciao means "hi" or "bye" in Italian) is a family of inexpensive mopeds produced by Piaggio from 1967 through 2006. 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. Braking is by front and rear drums. Power for the lamps, horn, and ignition is from a magneto; there is no battery. The Piaggio Si was a stablemates to the Ciao with a telescopic front fork suspension.
