A leaning vehicle includes a vehicle body, a left front wheel, a right front wheel, a lean mechanism, a lean brake mechanism, a steering handle, a left grip, a throttle grip, a lean brake manipulator. The lean mechanism causes the left front wheel and the right front wheel to lean about a front-rear direction as a rotation center when the vehicle body leans about the front-rear direction as a rotation center. The lean brake mechanism brakes the leaning operation by the lean mechanism while the leaning vehicle is traveling. The lean brake manipulator is positioned at a first side in the vehicle width direction, changes a position integrally with the left grip, and for performing an operation of actuating the lean brake mechanism to brake.

A shock absorber assembly including a first sheath slidingly housing inside it a first piston which is filled with hydraulic fluid, the first piston having a first stem extending from the first sheath and a first head contained inside the first sheath, a second sheath slidingly housing inside it a second piston which is filled with hydraulic fluid, the second piston having a second stem extending from the second sheath and a second head contained inside the second sheath. The first and second sheaths are fluidly connected to each other by means of at least one upper duct and a first interconnection duct passing through a control body. The control body houses at least one damping valve including a damping plate having holes suitable to allow a calibrated passage of the hydraulic fluid channelled by the first and second sheaths towards the control body; the control body houses a control valve connected to actuator means to be movable, in a regulation stroke, from an unlocked position, in which it does not interfere with the upper duct to a locked position, wherein the upper duct is occluded.

A tilting, preferably three-wheeled, vehicle is disclosed that has a tilting mechanism and a universal steering linkage that allows the vehicle to have leaning and steering characteristics substantially similar to those offered by an in-line two-wheeled vehicle, but that does not require complex linkages and/or control systems to operate effectively. A tilting linkage is operably secured to a frame to allow a pair of spaced apart wheels to remain substantially aligned with the plane of the vehicle throughout its range of movement while still providing an increasing camber between the wheels as tiling of the vehicle increases. A tilting lock system may be provide to limit tilting of the vehicle upon predetermined criteria.

A Steerable Crank System including a Steerer Base firmly connected to the chassis/mainframe of a machine, said Steerer Base containing and supporting Grooved Cog Wheel situated in-line and parallel to the power driving direction in a manner that allows said Grooved Cog Wheel to rotate around its axis and drive the machine power, said Steerer Base containing and supporting a Fork in a manner that allows said Fork to rotate around its main axis and by that rotation movement it controls the steering, said Fork containing a 2.sup.nd axis supporting and housing a Crank Shaft in a manner that allows said Crank Shaft to rotate around its own axis, on said Crank Shaft attached a Butterfly Connector, said Butterfly Connector coupling together said Crank Shaft and Grooved Cog Wheel.

A three-wheeled vehicle is disclosed having a vehicle frame supported by front ground engaging members and a single rear ground engaging member. The vehicle includes an engine positioned forward of an operator area and a swing arm coupled to the single rear ground engagement member. The operator area of the vehicle may include seating for a driver and a passenger.
