The Piaggio factory manufactured 17,000 Vespas of the Gran Turismo Replica model from 1968 to 1971.

In the year 1971, there were 5000 produced. At this time, only about 30% are still in circulation in the world.

The Gran Turismo Replica 125cc has the same frame as the 150 Sprint Veloce.

The only difference in the engine between the two is the reduced cylinder bore dimension of the Gran Turismo Replica.
