A motorcycle 10 has a secondary air supply system 70 which is provided between an air cleaner 40 and an exhaust passage of an engine 12 and by which secondary air is selectively supplied from the air cleaner 40 into the exhaust passage of the engine 12. The secondary air supply system 70 has a reed valve 72, which includes a front reed valve 73 used for a front cylinder 31 and a rear reed valve 74 used for a rear cylinder 32. The front reed valve 73 is disposed at a front portion 40a of the air cleaner 40, and the front reed valve members extend generally vertically. Thus, the secondary air supply system can be arranged efficiently and compactly. |
