Viberti is an Italian manufacturer of trailers and former producer of utility vehicles, buses and mopeds.
History.
The company was founded in 1922 to build civilian and military transport vehicles and was a supplier to the Italian armed forces during World War II. One of its products was the "Sahariana" armored car, but Viberti was better known by its integral "Monotral" chassisless self-supporting coaches and buses. 
Viberti also made the "Vi-Vi" moped from 1955 until 1957 in alliance with the German motorcycle producer Victoria.
In 2011 the trademark Viberti was sold to the Italian manufacturer Acerbi. Since 2016 Viberti is part of the Polish manufacturing group Wielton.
