Abstract
Air flowing through a secondary air inducting conduit of a motorcycle is effectively cooled to enhance combustion efficiency of exhaust gas in a catalyzer. A part of the secondary air inducting conduit is exposed to a space behind a front wheel and in front of an engine, and thus acts as a secondary air cooling conduit section for cooling down secondary air flowing through the secondary air inducting conduit.
