It's the smaller 1-1/4" receiver. The drawbar is installed in the picture. There are adapters to put it to 2" Most cars and small crossovers use the 1-1/4" as the 2 inchers are more for vehicles that carry heavier loads. Harbor freight sells an adapter that can be used for bike racks and such, but should not be towed with. https://www.harborfreight.com/1-1-4-quarter-inch-to-2-inch-hitch-adapter-65023.html
