CLAIMS
1. System to control the trim of motorcycles with three or four wheels, said motorcycle having two couples of front and rear wheels, or one front wheel and a couple of rear wheels, or a couple of front wheels and one rear wheel, said system to control the trim including, at one or both couples of wheels, a system of levers (1 ) which links the hubs of the couples of wheels with a central shock absorber (4), characterized in that it comprises at one or both the couples of wheels one or more dampers (5, 6) directly between said wheels of the couples, or between said system of levers (1 ) and a fixed point on the motorcycle chassis.
2. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said one or more dampers (5, 6) are connected between the hubs (2, 3) of the wheels and said fixed point on the motorcycle chassis.
3. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said one or more dampers (5, 6) are connected between said system of levers (1 ) and said fixed point on the motorcycle chassis.

4. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said one or more dampers (5, 6) are connected between said system of levers (1 ) and said hubs (2, 3) of the wheels.
5. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said one or more dampers (5, 6) are connected between a respective point (9') of a swingarm (9, 10) of the wheel and said fixed point on the motorcycle chassis.
6. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said central shock absorber (4) comprises a damper and a spring.
7. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said central shock absorber (4) comprises a spring.

8. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said system of levers (1 ), said central shock absorber (4), and said one or more dampers (5, 6) comprise two hydraulic cylinders (21 , 22) interconnected at the two ends through pipes (23, 24), in said cylinders respective pistons (25, 26) sliding by means of respective connecting rods (27, 28), in the cylinders being present a liquid able to flow between them through said pipes, said pistons dividing the chambers of the cylinders in two parts, not communicating, so that a fluid movement in the two upper chambers corresponds to an opposite movement in the lower chambers, said cylinders and said connecting rods being bound to the chassis or to a respective hub by fastening (21', 22', 27', 28').
9. System to control the trim of motorcycles with three or four wheels as in claim 8, characterized in that it further comprises an accumulator (29), the ends of which are hydraulically connected to said pipes (23, 24), in said accumulator being present two floating pistons (30, 31 ) forming a central chamber insulated from the rest of the hydraulic circuit, in which a gas in pressure is present.
10. System to control the trim of motorcycles with three or four wheels as in claim 8, characterized in that it further comprises two accumulators (29', 29"), one respective end of which being hydraulically connected to one of said pipes (23, 24), in each one of said accumulators being present a floating piston (33, 34) forming a chamber insulated from the rest of the hydraulic circuit, in which a gas in pressure is present.
11. System to control the trim of motorcycles with three or four wheels as in claim 1 , characterized in that said system of levers (1 ), said central shock absorber (4), and said one or more dampers (5, 6) comprise two hydraulic cylinders (21 , 22) interconnected at one of the ends through a pipe (23), in said cylinders respective pistons (25, 26) sliding by means of respective connecting rods (27, 28), said pistons dividing the chambers of the cylinders in two parts, not communicating, in the part of the cylinders communicating with said pipe (23) being present a liquid able to flow between them through said pipes, in the other closed part a gas in pressure being present, said cylinders and said connecting rods being bound to the chassis or to a respective hub by fastening (21', 22', 27', 28').
12. System to control the trim of motorcycles with three or four wheels as in claim 11 , characterized in that it further comprises an accumulator (29'), an end of which being hydraulically connected to said pipe (23), in said accumulator (29') being present a floating piston (33) forming a chamber insulated from the rest of the hydraulic circuit, in which a gas in pressure is present.
13. System to control the trim of motorcycles with three or four wheels as in claim 8 or 11 , characterized in that said hydraulic cylinders are connected between the hubs (2, 3) of the wheels and said fixed point on the chassis.
14. System to control the trim of motorcycles with three or four wheels as in claim 8 or 11 , characterized in that said hydraulic cylinders are connected between a respective point (9') of a swingarm (9, 10) of the wheel and said fixed point on the chassis.
