PURPOSE: To improve flow straightening effect and cooling effect around an engine by continuously providing right and left side parts of a cowling with a fuel tank, and introducing an upper end part of a chamber part in a right and left exhaust pipes along lower edges of the right and left side parts of the cowling backward. CONSTITUTION: Between a steering head pipe having a front fork 3 pivotally supported at a lower end and a seat 11, a fuel tank 13 is disposed. Under the fuel tank 13, a two-cycle multi-cylinder engine 6 is disposed, and under the seat 11, right and left foot rests 37 are disposed. In this constitution, right and left end parts of a cowling 23 covering the pipe are continuously provided with the fuel tank 13. A chamber part 36 in a right and left exhaust pipe 35 is introduced from right and left sides at a front end lower part of the engine 6 through a front part of the foot rest 37 upward. An upper end part of the chamber part 36 is introduced along a lower edge of a right and a left side part of the cowling 23 backward. |
