Abstract

The present invention is provides a secondary air leading-in device of two-wheeled automobile, To improve a secondary air suction system of a motorcycle so as to obtain a necessary amount by increasing a secondary air suction volume without affect of the output reduction, etc. In the motorcycle in which secondary air is supplied into the exhaust passage of an engine (16), a first air introducing passage (75) and a secondary air introducing passage (76) as a plurality of the secondary air introducing passages are installed in an exhaust pipe (33) as an exhaust passage. A secondary air is introduced into the exhaust pipe (33) from the first air introducing passage (75) and the secondary air introducing passage (76), and the secondary air introducing volume into the exhaust pipe (33) is increased to promote the oxidation of the unburned gas in the exhaust pipe (33).
