Abstract: The invention relates to a starting device (2), for a twin cylinder internal combustion engine (1) with cylinders (4, 5) in a V-format, comprising an electrical starter motor (19) and a gear assembly (20), coupled thereto for transmission of the output torque from the starter motor (19) to a crankshaft (14) in the motor (1) and an overrunning clutch (21) arranged between the gear assembly (20) and the crankshaft (14), such that the starter motor (19) and the gear assembly (20) are arranged in the V-shaped space (3) between the cylinders (4, 5) and above the crankshaft (14).

Abstract: The invention relates to a starting device (2), for a twin cylinder internal combustion engine (1) with cylinders (4, 5) in a V-format, comprising an electrical starter motor (19) and a toothed gear drive (20), coupled thereto for transmission of the output torque from the starter motor (19) to a crankshaft (14) in the motor (1) and a sprag clutch (21) arranged between the drive (20) and the crankshaft (14), such that the starter motor (19) and the drive (20) are arranged in the V-shaped space (3) between the cylinders (4, 5) and above the crankshaft.

Abstract: A clutch (1) for a motorcycle, having intermeshing plates (9, 10) associated with an inner and outer cage (22 and 23, respectively), and having a release actuator (3) for a pusher element (5) loaded by at least one clutch spring (8) for applying pressure on the plates (9, 10). The pusher element (5) is operable by a force opposite to the closing force of the clutch spring (8) in dependence on the engine load via a control means (11).

Abstract: A crankshaft drive in an internal combustion engine, which comprises at least one cylinder having a cylinder head, and a crankcase housing a crankshaft rotating at a predetermined direction and at a predetermined speed, and a balance shaft extending parallel to the crankshaft and rotating at the predetermined speed of the crankshaft in a direction opposite to the predetermined rotating direction of the crankshaft, the crankshaft and the balance shaft carrying balance weight means for balancing a mass of first order. An auxiliary shaft extends parallel to the crankshaft and rotates at the predetermined speed of the crankshaft in the predetermined rotating direction of the crankshaft, the auxiliary shaft carrying a counterweight for balancing a residual moment resulting from the rotating balance shaft with respect to the rotating crankshaft.
