A four-speed transmission (1) for motorcycles has performances similar to those of a continuously variable transmission but, at the same time, a high yield and an easy and automatic operation and it comprises: a crankshaft (2) with a first and a second pulley (9, 10) mounted thereon; a primary shaft (3), with third and fourth pulley (10, 14) and a first and a second gear (18, 19) mounted thereon; transmission belts (11, 13) connecting said pulleys for the transmission of the first and the second speed and of the third and the fourth speed respectively; a secondary shaft (4) with a third and a fourth gear (20, 21) engaged with said first and second gear (18, 19) for transmitting the first and the third speed, and the second and the fourth speed respectively; a first synchronizer (16), which activates the transmission of the third and the fourth speed; and a second actuated synchronizer (17), actuating the transmission of the second and the fourth speed; wherein a first and a second free wheel (15, 22) can release the transmission of the third and the fourth speed and of the first and third speed respectively.
