Gilera 150 Turismo 1954

In the early 1950s new regulations in Italy allowed access to motorways for motorcycles with a minimum capacity of 150cc, so Gilera upgraded its 125 to 150. The 150 presented in 1952 became Gilera's best-selling motorcycle ever, with 96,000 units produced (not including those built in Argentina).

The engine was revised by Antonio Parolo, Franco Passoni and Luigi Piazza under the supervision of the new director of the Gilera Experiment Service, Sandro Colombo, increasing the bore to 60 mm being the most notable change. The gearbox remained a 3-speed, with the Sport gaining a 4th gear in 1953. These models appeared in the catalogue until 1960.
