Abstract
An intake air passage, formed through a motorcycle body frame, reduces changes in pressure within an air routing duct member due to opening and closing of a throttle, and also reduces pipe resonance of the air routing duct member. The air routing duct member extends longitudinally from the intake air passage and directs fresh air to another air passage. The air routing duct member includes openings that communicate with hollow sections provided in a portion of an adjacent support structure, such as an instrumentation support member. When the throttle is opened rapidly, air from the hollow sections is temporarily supplied to the air routing duct member, reducing changes in internal air pressure in the air routing duct member due to throttle operation. Resonance chambers are formed above the air routing duct member, and communicate through communication pipes with a space within the air routing duct member to reduce duct pipe resonance.
