20130062135 | ENGINE UNIT AND TWO-WHEELED MOTOR VEHICLE WITH SAME - In an engine unit, a drive unit case includes a crank shaft disposed in a left-right direction of a vehicle, a drive shaft and a second main shaft. A transmission shaft is parallel or substantially parallel to the drive shaft and transmits rotational power, which has been transmitted via a middle gear, to a propeller shaft. A second clutch, which transmits rotational power from the crank shaft to the second main shaft, is freely detachably connected to an end of one side of the second main shaft which protrudes from a drive unit case more than the end of one side of the drive shaft, at a position that overlaps with at least one section of the middle gear on the side of the shaft direction of the drive shaft. | 03-14-2013 |
20130068551 | MOTORCYCLE - A motorcycle includes a vehicle body frame which extends in a front-rear direction of the vehicle, an engine unit that generates power that drives the motorcycle, a seat on which the rider sits, a storage box disposed below the seat, a fuel tank that stores fuel needed by the engine unit, and an air filter disposed above the engine unit to filter the air needed by the engine unit and includes an air intake hose to introduce air. The fuel tank is disposed below the seat and is located in front of the storage box. Moreover, the fuel tank is mounted on the vehicle body frame, and the air intake hose extends from the air filter toward an area between the fuel tank and the storage box such that a air inlet thereof is located in a space between the fuel tank and the storage box. | 03-21-2013 |
