A method of making a bicycle sprocket having a rotational center axis basically includes providing an annular portion and forming a first tooth and a second tooth. The annular portion is made of a base material and has a plurality of teeth. At least one of the teeth is processed to form a first tooth, and at least one other of the teeth is processed to form a second tooth. The first tooth has a first axial chain engaging width that is smaller than a first axial spacing of an outer link of a bicycle chain and larger than a second axial spacing of an inner link that is coupled to an outer link. The second tooth is formed to have a second axial chain engaging width that is smaller than the second axial spacing. The second tooth is formed by deforming the base material.
