Motorcycle cooling system

摘要

A cooling system for the internal combustion engine of a motorcycle includes a radiator and means defining air passages each having a forwardly facing inlet opening disposed respectively on the opposite sides of the motorcycle's front fork. Each air passage extends rearwardly from the inlet opening to an outlet which opens into a plenum chamber disposed adjacent the radiator. The cross-sectional area of each passage increases gradually between its inlet and outlet ends. An exhaust duct is connected to the plenum chamber and the radiator is disposed between the plenum chamber and the exhaust duct.
