PURPOSE:To increase the minimum height from ground level thus to improve the coarse road traveling performance, by projecting a cylinder in an engine to the traveling direction while opening the exhaust port and suction port to the side of space formed between the engine and fuel tank. CONSTITUTION:A pair of fuel tanks 44 are fixed together with an air cleaner 42 across a main pipe 14, while an engine 54 is fixed below to a lower arm 18. Here the engine 54 is provided with a cylinder 58 projecting from a crank case 56 to the traveling direction while an exhaust port 60 and a suction port 66 are arranged in a space formed between the upper face of the cylinder 58 or the fuel tank 44 and the engine 54 and an exhaust tube 62 and a suction tube 70 connected to each opening 60, 66 respectively are arranged. Consequently a wide space can be formed between the fuel tank 44 and the engine 54 thereby the engine 54 can be brought near to the fuel tank 44. |
