Abstract:
A continuously variable transmission device (1) for a two-wheel, three-wheel or four-wheel motorcycle includes a cam system (20, 22; 32a, 32b) operating between a fixed bushing (11) and a mobile bushing (9). The device is configured to obstruct the approach between the active surfaces (8a, 10a) or to facilitate the approach of the active surfaces.
