PROBLEM TO BE SOLVED: To provide an exhaust device of a motor cycle that can detect oxygen in exhaust gas in a state that the exhaust gas is sufficiently stirred, and can reduce a catalyst in size.SOLUTION: An exhaust device 40 comprises right and left exhaust pipes 41R, 41L, and mufflers 44L, 44R connected to the downstream sides of the exhaust pipes 41. The pair of right and left exhaust pipes 41R, 41L comprise collection parts 43R, 43L, respectively, and the collection parts 43R, 43L are provided with catalysts 48R, 48L. The pair of right and left exhaust pipes 41R, 41L include, on the downstream sides of the catalysts 48R, 48L, branch parts 55R, 55L in which one sides extend to the mufflers 44R, 44L and the other sides extend to a connecting pipe 54, and comprise an oxygen sensor 52 on one side on the downstream sides of the pair of right and left branch parts 55R, 55L.SELECTED DRAWING: Figure 3 |
