An upper pipe 55 includes a single front pipe portion 68, a branch portion 69 bifurcated from the rear end of the front pipe portion 68, and two left and right rear pipe portions 71L, 71R extending vehicle-rearward from the branch portion 69. A cylinder head cover 58 is located between the two left and right rear pipe portions 71L, 71R as viewed from above. Therefore, the cylinder head cover 58 can be accessed from above and removed from a cylinder head, whereby a valve train chamber can be inspected and maintained. |
