Abstract: A two or three-wheeled vehicle, motorized or not, in which the handle-bar and the front fork are hinged to the steering hub so that they can be upset from their normal operative position to a contracted vehicle position reduced in overall dimensions, in which the front wheel center is put underneath the frame front part and the handle-bar is upset in an essentially horizontal way, so reducing the vehicle overall dimensions in length and in its front part height.

Abstract: A moped comprises a beam-type frame having a substantially horizontal central portion, to one end of which there is connected a front portion that carries the articulation of the front-wheel fork, and the other end of which extends to become an upwards-slanting rectilinear portion carrying at its end the support elements for the saddle and the rear mudguard. Said central portion is adapted, as a result of its width and length, to constitute a footrest, and said extended end, as a result of its dimensions and slanting upwards at an angle of less than 45.degree., is adapted to consitute a luggage carrier or a second footrest.

Abstract: This invention relates to an improvement in devices for controlling the transmission ratio variation in continuous variators disposed between a vehicle engine and its wheels. The improvement comprises a supplementary control which modifies that action on the device which is dependent on the engine feed, in particular to obtain effective engine braking action during vehicle deceleration.

Abstract: This invention relates to a variable ratio transmission system suitable for vehicles in which the speed regulator is mounted on the transmission driven shaft, and the relationship governing its response to the speed variation of the driven shaft is such as to induce a transmission ratio variation to predetermine the speed of the system input shaft, which is intended for connection to the drive shaft. Means are also provided for connection to engine regulator means, in order to determine the constant speed of the system input shaft as a function of the torque applied to the transmission input shaft.

Abstract: In a variable-transmission-ratio mechanical drive of the continuous variation type having a V-belt and expansible sheaves, in which each sheave has a fixed half-sheave and a movable half-sheave the position of only one of the movable sheaves is determined as a function of the speed and the load of the engine by an automatic positioning servomechanism, whereas the other movable half-sheave is subjected only to the axial load of a member which is adapted to cause the belt to adhere to said expansible sheaves.

Abstract: A bearing body for motorcycles with rear drive wheel borne in cantilever fashion by an oscillating arm fulcrummed to said body and bearing also the engine/transmission assembly with related exhaust pipe silencer, comprising in its lower part anterior to the fulcrum of said oscillating arm a cavity for free partial housing of said silencer.

Abstract: A bearing body for motorscooter, comprising lateral cowls formed solidly therewith, also comprising releasable restraining means for securing a spare wheel to the side of the body within one of said cowls, there being also a lockable aperture, proximal to said securing means, inside said cowl.

Abstract: This invention relates to a drive wheel for motor vehicles, in particular motorcycles, having an internal combustion engine arranged in the wheel interior. According to the invention, the wheel rotates about a pivot fixed to the engine block and receives its motion, through a suitable transmission, from a drive shaft emerging from that side of the engine block opposite the side to which the wheel support pivot is fitted. This arrangement of the wheel and the drive shaft enables the internal space of the wheel to be utilized to the maximum extent for arranging the engine-transmission assembly in suitable manner.
