1 is a down tube that forms part of the vehicle frame;
2 is a front fork, 3 is a steering wheel, 4 is a front wheel, 5 is a fuel tank, 6 is a seat, and 7 is a water-cooled V type vertically mounted engine supported by a down tube 1 below the fuel tank 5. A horizontally long box-shaped radiator 8 is placed in front of the cylinder and cylinder head of the engine 7 and is connected to a down tube 1.
It is installed on. Further, the engine 7 is of a cross flow type.
