Why would a bike blow out coolant?

Why would a bike constantly blow out coolant from overflow?

Am I correct in assuming it is either faulty radiator cap or pressure from engine getting into cooling system via leaking gasket ?

Bike has lost 2/3 of coolant from reservior in 1600km. All blown from overflow pipe.
