A speed-changing device for a two-wheeled vehicle (2) comprising: - circular support means (3A, 3B) suitable for being mounted on a hub (4) of a wheel (5) of the two-wheeled vehicle (2), - a plurality of lamellar meshing elements (6) supported by the circular support means (3A, 3B) and radially arranged around a rotation axis (A), the lamellar meshing elements (6) being arranged for engaging with a transmission element (T) of the chain or belt type of the vehicle (2), - each lamellar element (6) being provided with a shaped meshing edge (S) comprising a sequence of zones (Z1, Z2,..., Zn) located at different distances from the axis (A) of rotation, - the meshing lamellar elements (6) being grouped in a first series (W1) of lamellar elements (6) of meshing and a second series (W2) of meshing lamellar elements (6) mutually opposite and movable to and from one another to change a meshing radius (R) with the transmission element (T) and thus vary a corresponding kinematic transmission ratio, - a distance-adjusting member (10) actuatable to move the first series (W1) and the second series (W2) of meshing lamellar elements (6) towards and away from one another.
