Abstract: A single-track vehicle, in particular a motorcycle, includes a frame, a rocker rotatable relative to the frame, and a leaf spring connected to the frame and to the rocker to achieve a spring effect between the rocker and the frame. The leaf spring is connected to the frame via a first lever and a first rotary bearing such that a first rotational axis of the first rotary bearing is transversely offset relative to the leaf spring as a result of the first lever. Alternatively or in addition, the leaf spring is connected to the rocker via a second lever and a second rotary bearing such that a second rotational axis of the second rotary bearing is transversely offset relative to the leaf spring as a result of the second lever.

Abstract: Technologies and techniques for reducing a collision risk between a first motor vehicle and a second motor vehicle. At least a first vehicle-to-environment message is transmitted by the first motor vehicle and received by the second motor vehicle. Using a second computing unit of the second motor vehicle, it is determined, depending on the vehicle-to-environment message, whether a risk situation exists in which the first motor vehicle is obscured by a preceding third motor vehicle. The second computing unit executes a criticality analysis to determine that the risk situation exists and, depending on the result of the criticality analysis, a risk-reducing measure is initiated.

Abstract: A valve train device includes a shaft having one or more actuation contours for actuating at least one actuation element of a valve of a combustion engine, and the actuation contours being arranged on the shaft so as to rotate therewith. A sensor unit including one or more sensors is provided, and each of the one or more sensors has a spatial sensing area for sensing a physical variable. In at least one axial position, an actuation contour of the one or more actuation contours is arranged at least partially in the spatial sensing area of a sensor of the one or more sensors.

Abstract: A system having a motorcycle and a transportable radio device. The motorcycle has a frame with a steering head bearing seat and a drive unit, and a switch unit and a control device. The control device has wireless communication with the radio device for controlling operating modes of the motorcycle, depending on an authentication information transmitted from the radio device to the control device. The control device is configured for wireless transmission to the radio device of a blocking information which shifts the radio device into a sleep mode, in which mode communication of the radio device to the control device ceases. The control device also is configured for wireless transmission of a first and/or second piece of time interval information relating to the length of a first and/or second time interval to the radio device, at the end of which the radio device is shifted into the sleep mode.

Abstract: A vehicle, in particular motorcycle, includes a frame, handlebars with two handlebar grips and a communication unit with at least one sensor for the acquisition of data relating to the vehicle, and an interface for transmitting the acquired data. A handlebar protector is arranged, preferably centrally, between the handlebar grips and the communication unit is arranged underneath the handlebar protector or at least partially, preferably entirely, within the handlebar protector.

Abstract: A motorcycle (1) is proposed in which a grip opening (29) forms a part of the flow path of the intake air of the engine (2). This grip opening (29) is formed by gaps (5) in the side spoilers (3, 19) and a recess (8) in the rear frame (6). Arranged at the recess (8) are the air inlet openings (11, 12, 13, 31, 32) of the air guidance device (9) in which the air filter element (7) for cleaning the intake air of the engine (2) is located.

Abstract: A gearshift lock for a gearbox includes a gearshift cylinder and a pawl wheel with a toothing. The gearshift lock includes a rotatably positioned pawl, and the pawl engages in the toothing of the pawl wheel in a locked position, and is disengaged from the pawl wheel in a freewheeling position. The pawl is pretensioned by a spring element in the direction of the locked position, and an engagement element is connected to the pawl. The engagement element holds the pawl in the freewheeling position by directly interacting with the gearshift cylinder against the effect of the spring element when the gearshift cylinder takes up a rotational position in a freewheeling rotational range, and the pawl can be released from the gearshift cylinder into a locked position by the engagement element when the gearshift cylinder takes up a rotational position in a locked rotational range.
