Piaggio & C. S.p.A.

A transport vehicle ( 1 ) comprising: —a heat engine ( 8 ) operable at a number of revolutions varying between a minimum number and a maximum number; —an adjusting device ( 52 ) configured to adjust an infeed flow of air-fuel mixture to the heat engine ( 8 ); —at least one on-board memory unit ( 61 ) in which an acoustic emission map ( 70 ) of the transport vehicle ( 1 ) is stored, wherein for each data pair comprising a first data item correlated to an operating condition of the adjusting device ( 52 ) and a second data item correlated to the number of engine revolutions, the acoustic emission map ( 70 ) associates, as a function of the first data item and as a function of the second data item, a third data item correlated to an acoustic emission measurement by at least one acoustic sensor (S 1 ) external to the transport vehicle ( 1 ) and arranged at a separation distance from the transport vehicle ( 1 ).

A rideable saddle vehicle including: a taillight arranged on a rear-carriage of the vehicle, the taillight being adapted to emit a light beam; a rear fender of a rear wheel connected to an unsprung mass portion of the rear-carriage, the rear fender having a front edge and a rear edge; a detection unit arranged on the rear-carriage and configured to detect the presence of other vehicles in a zone behind the vehicle, where the detection unit, in a side view of the rideable saddle vehicle, is arranged below the taillight, above the rear edge of the rear fender, behind the front edge of the rear fender and in front of the rear edge of the rear fender.

A three- or four-wheeled rolling motor vehicle including a main body having a front portion, a middle portion, and a tail portion; three or four wheels constrained to the main body, including at least two wheels arranged at the front portion or at the tail portion, a traction engine operatively connected to one of the wheels, a roll locking system of the wheels, controllable between a locking operational state and an unlocking operational state, an electronic control unit configured to control the roll locking system, wherein the electronic control unit has a first processing unit configured to receive and process a first input signal to establish the locking operational state or the unlocking operational state, where the electronic control unit includes a second processing unit configured to receive and process a second input signal to determine whether a safety condition is met, and provide consent to control the locking system to take or maintain the locking or the unlocking operational state, where the first and the second input signal comprise a first plurality of signals and a second plurality of input signals with at least one signal in common.

A boot for a motorcyclist, including an upper portion integrally connected to an outsole, the upper portion having a leg portion and a foot portion integrally connected to each other by means of an ankle portion, the leg portion including a shin portion and a calf portion, and the foot portion having a heel portion and a vamp portion, and a curved coverture configured to cover an outer side of the leg portion of the boot, the curved coverture being shaped according to an airfoil and including a leading edge arranged in correspondence of the shin portion and a trailing edge arranged in correspondence of the calf portion.

A three- or four-wheeled rolling motor vehicle including a main body having a front portion, a middle portion, and a tail portion; three or four wheels constrained to the main body, including at least two wheels arranged at the front portion or at the tail portion, a traction engine operatively connected to one of the wheels, a roll locking system of the wheels, controllable between a locking operational state and an unlocking operational state, an electronic control unit configured to control the roll locking system, wherein the electronic control unit has a first processing unit configured to receive and process a first input signal to establish the locking operational state or the unlocking operational state, where the electronic control unit includes a second processing unit configured to receive and process a second input signal to determine whether a safety condition is met, and provide consent to control the locking system to take or maintain the locking or the unlocking operational state, where the first and the second input signal comprise a first plurality of signals and a second plurality of input signals with at least one signal in common.

The motorcycle ( 100 ) comprises a front steering wheel ( 2 ), a rear driving wheel ( 3 ), a saddle ( 4 ) adapted to receive a rider ( 200 ), a handlebar ( 5 ) configured to steer the front wheel ( 2 ), a fairing ( 1 ) adapted to cover at least part of an engine ( 7 ). The fairing ( 1 ) comprises a bottom portion ( 8 ) to which two side portions ( 9 ) are connected, in turn comprising an upper side portion ( 9 A) and a lower side portion ( 9 B). Each of the lower side portions ( 9 B) comprises an outer surface ( 10 ) shaped so that first section profiles ( 10 A) according to transversal planes (T) orthogonal to a midplane (M) of the motorcycle ( 100 ) are linear. The lower side portions ( 9 B) are shaped so that, observing the motorcycle ( 100 ) from the front, they form a V-shaped profile with the bottom portion ( 8 ).

A lamp for a saddle-ride type vehicle includes a casing having a front aperture and a light source attached to the casing. A reflector is configured to reflect the light emitted by the light source, and a diffuser is arranged in front of the reflector. A clear cover attaches to the casing and defines, together with the casing, a space in which the light source, the reflector, and the diffuser are arranged. The diffuser is shaped to include mutually alternating ridges and valleys. A vehicle of the type with a saddle includes the lamp.
