Abstract
A water cooled motorcycle wherein a curved radiator is disposed behind the steering shaft and inclined substantially at the same angle as the steering shaft so as to provide adequate air flow through the radiator without the engine heat being transmitted from the external portion of the engine to the radiator. Other embodiments disclose the use of lower radiators and series or parallel flow paths between the upper and lower radiators.
Claims26
A cooling system for a motorcycle having a body assembly suspended upon a dirigible front wheel and a rear wheel, a steering shaft rotatable about an upstanding axis inclined from the vertical in a generally rearwardly inclined fashion and disposed above said front wheel for steering said front wheel, an internal combustion engine supported by said body assembly and driving at least one of said wheels, said engine being at least partially water cooled, and a radiator supporting contiguous to and to the rear of said steering shaft through which coolant is circulated from said engine, said radiator having a core inclined to the vertical at substantially the same angle as the steering shaft and entirely forwardly of the rear portion of said front wheel lying at its center behind said steering shaft and above said front wheel.
A cooling system for a motorcycle having a body assembly suspended upon a dirigible front wheel and a rear wheel a steering shaft rotatable about an upstanding axis inclined from the vertical in a generally rearwardly inclined fashion and disposed above said front wheel for steering said front wheel, an internal combustion engine supported by said body assembly and driving at least one of said wheels, said engine being at least partially water cooled, a first cross flow radiator supported contiguous to and to the rear of said steering shaft, a second down flow radiator disposed below said first radiator, and means for circulating coolant first through said first radiator from one side to the other side therein and therein downwardly through said second radiator from said engine.
