A saddle-ride type vehicle comprising an engine, a gearbox and a clutch assembly interposed between said engine and said gearbox, wherein said clutch assembly comprises: - a clutch device comprising at least one drive element integral with the shaft of said engine, at least one driven element integral with an input shaft of said gearbox and return means that keep said elements (11A, 11B) in contact in a closure condition of said clutch device; - an operating device of said clutch device to cause, in opposition to said return means, a mutual detachment of said elements (11A, 11B) up to an opening condition of said clutch device, wherein the vehicle also comprises a control device of said clutch assembly, wherein said control device comprises an actuation means that, during a gear change performed by said gearbox following a pilot command, exerts a predetermined force in contrast to the force exerted by said return means, said predetermined force being less than said force exerted by said return means so as to cause said clutch device to slip without said opening condition being reached; wherein said operating device is of hydraulic type and comprises a primary pump operated by means of a control lever, wherein said primary pump is hydraulically connected, through a primary hydraulic circuit, to a primary piston acting on at least one of said elements (11A,11B) of said clutch device in opposition to said return means so that, as a result of an action on said control lever, said primary piston exerts an action on said elements (11A,11B) determining said opening condition; wherein said control device comprises a secondary piston connected to said primary piston, wherein said actuation means exerts, directly or indirectly, said predetermined force on said secondary piston, said predetermined force being transferred to said primary piston in opposition to said force of said return means. - a clutch device comprising at least one drive element integral with the shaft of said engine, at least one driven element integral with an input shaft of said gearbox and return means that keep said elements (11A, 11B) in contact in a closure condition of said clutch device; - an operating device of said clutch device to cause, in opposition to said return means, a mutual detachment of said elements (11A, 11B) up to an opening condition of said clutch device, wherein the vehicle also comprises a control device of said clutch assembly, wherein said control device comprises an actuation means that, during a gear change performed by said gearbox following a pilot command, exerts a predetermined force in contrast to the force exerted by said return means, said predetermined force being less than said force exerted by said return means so as to cause said clutch device to slip without said opening condition being reached; wherein said operating device is of hydraulic type and comprises a primary pump operated by means of a control lever, wherein said primary pump is hydraulically connected, through a primary hydraulic circuit, to a primary piston acting on at least one of said elements (11A,11B) of said clutch device in opposition to said return means so that, as a result of an action on said control lever, said primary piston exerts an action on said elements (11A,11B) determining said opening condition; wherein said control device comprises a secondary piston connected to said primary piston, wherein said actuation means exerts, directly or indirectly, said predetermined force on said secondary piston, said predetermined force being transferred to said primary piston in opposition to said force of said return means.
