The invention claimed is: 1. Four-wheeled vehicle (1) with two steered front wheels (2, 3) comprising a frame (13), handlebars (16), two rear wheels (4, 5) and a front suspension group (6) that acts upon said two front wheels (2, 3) characterized in that said front suspension group allows the roiling of the vehicle and comprising at least two shock absorbers (22), at least two horizontal cross members (7,8) comprising at least one lower cross member and one upper cross member connected through at least two hinges (9,9',10,10') to said frame (13) and at least two vertical suspension elements (11,12) firmly connected to said at least two horizontal cross members (7,8) so as to form an articulated quadrilateral for the rolling of the vehicle (1), said horizontal cross members (7,8) are connected at their ends to said vertical suspension elements (11,12) through hinge elements (57) wherein said front suspension group (6) also comprises at least two cylindrical hinges (66) to connect connecting rods (60) to said shock absorbers (22) where said shock absorbers (22) are also connected to said middle of the upper cross member (7) through said hinge (9). 2. Four-wheeled vehicle (1) according to, claim 1 characterized in that at least one of said horizontal cross members (7,8,8') is made in two elements (8,8') connected to said frame (13). 3. Four-wheeled vehicle (1) according to claim 1, characterized in that each of said vertical suspension elements (11,12) has an arched shape suitable for at least partially surrounding said front wheel (2 or 3) to reduce the transversal bulk of said vehicle (1). 4. Four-wheeled vehicle (1) according to claim 3, characterized in that said lower cross member (8) comprises two half-arms (8',8"), each half-arm (8',8") extending from a central hinge (10',10') to an end hinge (57). 5. Four-wheeled vehicle (1) according to claim 4, characterized in that said connecting rods connect said upper cross member (7,8) to each vertical suspension element (11,12). 6. Four-wheeled vehicle (1) according to claim 5, characterized in that said front suspension group (6) also comprises rods at least one ball joint (62) to connect said connecting rods (60) to said vertical suspension elements (11,12).
