Abstract: An electronic throttle control device for motorcycles or other similar vehicles with two, three or four wheels, snowmobiles or the like comprising a handlebar (3) on which a rotary handle control (2) is positioned cooperating with electrical/electronic measurement means for measuring its rotation and/or angular position about the axis (W) of the handlebar (3), to hence control a usual element for modifying the vehicle engine r.p.m., i.e. to control the throttling of this latter, said means comprising, functionally rigid with the handle control (2), a first component generally defined by a rotor (12) arranged to cooperate with a second component, generally a position or angular sensor, of said means fixed on the handlebar (3). A grooved insertion piece (8) is provided rigid with the handle control (2) and arranged to cooperate torsionally with said rotor (12), between said insertion piece (8) and said rotor (12) there being a small degree of slack when the handle control is in the zero throttle position.

Abstract: A handlebar (1) for a vehicle such as a motorcycle or a two, three or four wheeled motor vehicle, a snowmobile or a seamobile, comprises a body (2) presenting a central portion (3) and final portions (4, 5) of constant cross-section, the central portion (3) and each final portion (4, 5) being connected together by a corresponding intermediate portion (7, 8) also of at least partly constant cross- section shape; each intermediate portion (7, 8) presents, in proximity to the central portion (3) and to the corresponding final portion (4, 5), end regions (12, 13) having sudden cross-section variations such as to define elastic regions acting as elastic hinges for the connection of said intermediate portion (7, 8) to the adjacent portions (4, 5), and to enable the handlebar (1) to undergo a controlled deformation thereat when subjected to stress during vehicle use.
