Abstract

A scooter type motorcycle capable of improving cooling efficiency of brake calipers includes a vehicle body cover, covering a rear wheel brake device, is formed with a drive-induced airflow introducing port. A drive-induced airflow guiding duct, supported with vehicle body frames, for guiding drive-induced airflow from the drive-induced airflow introducing port to the brake calipers of the rear wheel brake device, is provided. The drive-induced airflow guiding duct has an inflow port formed at its one end for the drive-induced airflow entering at the drive-induced airflow introducing port to flow in. An airflow delivery port is formed at its other end and opening in the vicinity of the brake calipers for delivering the drive-induced airflow, introduced through the inflow port, to the brake calipers.
