Abstract: An air suction device for a vehicle equipped with an internal combustion engine. The air suction device includes a device guiding purified suction air for combustion in the direction of the internal combustion engine, and an air filter element and a housing receiving the air filter element, and at least one air guiding device. The air guiding device is formed in the shape of a channel and is provided for guiding suction air to the housing. The air guiding device extends in the region between a holding device and the housing. The holding device is formed to receive at least one light source and has an air leading channel adjacent to the light source, which is connected in an air guiding manner to the air guiding device.

Abstract: A two-stroke internal combustion engine having at least one cylinder provided with a combustion chamber and an outlet and having a crank housing provided with a crank shaft. The housing is flow-connected to the combustion chamber via at least one transfer port, and the internal combustion engine is formed to inject fuel into the transfer port, against the transfer port from the crank housing into the combustion chamber; the internal combustion engine has at least one cylinder having two injectors, and fuel can be introduced by means of only one injector with a first engine load and by means of the two injectors with a second engine load.

Abstract: A vibration damper for use particularly on wheeled vehicles. The damper has a cylinder formed to receive damping fluid and a working piston axially moveable therein, which piston is arranged on a piston rod formed with an axial passage and which divides the inner space of the cylinder into first and second working spaces. The vibration damper has a fluid communication axial passage for a fluid flow from the second working space to the first working space, and has a first adjustment device for adjusting the pressure stage damping and a second adjustment device for adjusting the traction stage damping. The first adjustment device has adjustable valve devices to change throughflow openings for the pressure stage, and the second adjustment device has a setting rod arranged in the axial passage of the piston rod for changing a first throughflow opening of a third valve device for the traction stage.

Abstract: An apparatus and system for actuating a manual gearbox, particularly of a motorcycle having a drive engine, and for carrying out a gear change while the clutch is engaged between the drive engine and the manual gearbox. The apparatus has a selector shaft, which can be actuated rotationally, and a gear-selector drum, which can be actuated rotationally. The gear-changing apparatus has a gear-change lever provided for actuating the selector shaft, and is adapted for influencing the output torque of the drive engine. One or more magnetic sensor(s), such as Hall effect sensors, are provided for sensing rotational actuation of the selector shaft and, optionally, for sensing rotational actuation of the gear selector drum.
