1. A radiator that is disposed behind a front wheel of a saddle riding vehicle, the radiator comprising:
a first tank and a second tank configured to store cooling water, wherein the first tank is disposed at an upper portion of the radiator and the second tank is disposed at a lower portion of the radiator; and
a core configured to connect the first tank and the second tank to each other, wherein
the core includes a plurality of cooling water pipes configured to flow the cooling water between the first tank and the second tank, and a plurality of fins extending between the plurality of cooling water pipes to promote heat dissipation from the cooling water pipes,
the core further includes a flow surface through which air can flow when the saddle riding vehicle is moving, the flow surface including a recess, and
when viewed from a side view of the saddle riding, vehicle:
a front surface of the radiator is shaped to expand forward along a vehicle body frame of the saddle riding vehicle as the radiator extends upward from the lower portion of the radiator;
a back surface of the radiator tilts forward as the back surface extends vertically in the side view of the saddle riding, vehicle; and
the upper portion of the radiator is formed thicker than the lower portion of the radiator in the front-rear direction of the saddle riding vehicle.
 
6. A radiator that is disposed behind a front wheel of a saddle riding vehicle, the radiator comprising:
a first tank and a second tank configured to store cooling water, wherein the first tank is disposed at an upper portion of the radiator and the second tank is disposed at a lower portion of the radiator; and
a core connecting the first tank and the second tank to each other, wherein
the core includes a plurality of cooling water pipes configured to flow the cooling water between the first tank and the second tank, and a plurality of fins extending between the plurality of cooling water pipes to promote heat dissipation from the cooling water pipes, and
the core is disposed to extend to the outside of the first tank and the second tank in the vehicle width direction such that an outermost portion of the core is disposed outside outermost portions of the front wheel of the saddle riding vehicle in the vehicle width direction so air can flow through the plurality of fins when the saddle riding vehicle is moving.
