A motorcycle fluid cooler assembly includes a heat exchanger and a mounting member coupled to the heat exchanger. The mounting member is adapted for mounting the heat exchanger to a first footrest mounting point of a motorcycle frame so that the heat exchanger transversely extends externally to the motorcycle frame when mounted. Fluid ports are coupled to the heat exchanger, and a footrest member is coupled to the heat exchanger. The footrest member is positioned as a rider footrest when the heat exchanger is mounted.
