Radiator for a two-wheeled motor vehicle with a lateral V-type crankshaft straddle type engine. The radiator is attached to the front section of the down tubes and comprises an upper section between an upper tank connected to coolant recovery piping and a middle tank, and a pair of lower sections between the middle tank and a pair of lower tanks supplying coolant piping at both sides. One of the lower tanks is lower than the other, with a connecting pipe between them inclined so as to equalize the coolant flow speed.
