The radiator-oil cooler is for a motorcycle with coolers (23L,23R) on each side of water cooled engine (E) mounted in a frame (5). The coolers are angled on each side of the motor, so that the upper ends have a wider spacing than the lower ends. The front edges of the coolers are positioned over the front end of the engine. An air cooled oil cooler (30) is positioned in front of the engine in the transverse space between the upper edges of the cooler.
