Continuously variable transmission provided with a primary pulley and a secondary pulley, around which a drive belt is arranged, clamped between two conical pulley discs of the respective pulley, a running surface of at least one pulley disc of the primary pulley and the secondary pulley, via which running surface this pulley disc contacts the drive belt, being provided, as seen in a cross section oriented perpendicular to a tangential direction, with a curvature, so that a pulley angle between a tangent on the running surface and a radial direction varies between a lowest value at the location of a radially innermost position on the running surface and a highest value at the location of a radially outermost position on the running surface. The curvature of the running surface of the primary pulley and that of the running surface of the secondary pulley differ from one another.
