Abstract
Abstract A radiator for a motorcycle having a core with an arcuate front surface. The radiator tanks remain parallel. The radiator is retained by means of a pin and fastener means nonconcentrically arranged to insure proper mounting under heavy load road conditions. The tubes of the core may be arranged in either vertical or horizontal extension and may be arcuate to define the concave front surface of the core. Straight tubes of varying width may also be employed to define the arcuate front surface.
