Motorcycle cooling system
First Claim
1. A motorcycle including front and rear forks for mounting front and rear wheels respectively, a frame interconnecting said forks, a liquid cooled internal combustion engine and a radiator for said engine supporting on said frame and between said forks, the improvement comprising an air transport system for said radiator including:
- means defining first and second air passages each having a forwardly facing inlet opening disposed respectively on the opposite sides of said front fork,each air passage means extending rearwardly from its inlet,means defining a plenum chamber disposed adjacent said radiator,said air passages having an outlet opening into said plenum chamber,the cross sectional area of each passage increasing gradually between its inlet and outlet ends,an exhaust duct connected to said plenum chamber,said radiator being disposed between said plenum chamber and said exhaust duct and creating a substantial resistance to air flow therebetween.

Abstract
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.

8. A cooling system for a liquid cooled motorcycle engine including a radiator for dissipating heat from the engine cooling liquid,
first and second conduit means each defining air passages and having an inlet opening spaced one from the other and from said radiator, means defining a plenum chamber disposed adjacent said radiator, said conduit means each extending from its inlet opening to said plenum chamber and having an outlet opening into said plenum chamber, the cross sectional area of each passage increasing gradually between its inlet and outlet ends, an exhaust duct connected to said plenum chamber and extending downwardly therefrom, said radiator being disposed between said plenum chamber and said exhaust duct and creating a substantial resistance to air flow therebetween.
