Abstract
A secondary air supply system is arranged efficiently and compactly, in a V-type engine including a front-side cylinder and a rear-side cylinder. A motorcycle has a secondary air supply system which is provided between an air cleaner and an exhaust passage of an engine. The secondary air is supplied from the air cleaner into the exhaust passage of the engine. The secondary air supply system has a reed valve in a position for being exposed to the exhaust passage. The reed valve includes a front-side reed valve used for a front-side cylinder and a rear-side reed valve used for a rear-side cylinder. The front-side reed valve is disposed at a front portion of the air cleaner, with the longitudinal direction of the front-side reed valve set along the height direction.
