A balanced motorcycle powertrain is described. Embodiments of the balanced motorcycle powertrain include components mounted to a frame of a motorcycle such that the powertrain can be evenly balanced about a centerline of the frame. The balanced motorcycle powertrain can include, but is not limited to, a motor, a transmission, a pair of clutches, a clutch shaft, a crank shaft, a pair of superchargers, a pair of chains, a pair of rear sprockets, and a rear wheel. Each of the components can be oriented such that the powertrain is substantially balanced about the centerline of the frame.

An epicyclic gear system includes an input sun gear configured to receive rotational input from a turbine of a turbo charger. A first set of planet gears is distributed around and meshes with the input sun gear. A carrier holds the first set of planet gears and defines a rotational axis about which the carrier rotates. A second set of planet gears is mounted to the carrier. An output sun gear is included, wherein the second set of planet gears are distributed around and mesh with the output sun. The output sun gear is configured to deliver rotational power to an internal combustion engine. The carrier is configured to selectively be driven by a variable speed drive to regulate output to the output sun over a range of input rotational speeds of the input sun gear.

An OHV engine includes V-shaped banks, a crank shaft, a cam shaft connected to the crank shaft, a mechanical supercharger located between the V-shaped banks, and a power transmission supported by the cam shaft and that connects the crank shaft to the mechanical supercharger. The power transmission includes a gear mechanism with a gear ratio not greater than a predetermined value, and includes a first gear supported rotatably by the cam shaft and that rotates based on an output from the crank shaft, a second gear provided on a rotation shaft of the mechanical supercharger, and an idle gear that connects the first and second gears with each other. Cylinders are offset with respect to a center of the crank shaft on an anti-thrust side of the cylinders, and the mechanical supercharger is also offset with respect to a center of the crank shaft on the anti-thrust side. Cylinder heads are provided with oil cooling paths adjacent respective spark plugs.

A low-temperature turbocompressor structural arrangement for an internal combustion engine for using energy that is available but unused during operation to cool the air supplied to the engine by supercharging. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine. The structural arrangement may be mounted in full or in part, and also each component may be fitted into existing systems.
