PROBLEM TO BE SOLVED: To achieve downsizing and weight saving of a hub.SOLUTION: A spoke wheel for a motorcycle comprises: a hub 2 having an insertion hole 26 into which a wheel shaft 9 is inserted; a rim to which a tire is mounted; and a plurality of spokes for connecting the hub and the rim. The spoke comprises a first spoke extending from one side of the hub to the rim in an axial direction D1 of the insertion hole, and a second spoke extending from the other side of the hub to the rim in the axial direction. A storage part 22 for storing a damper member 27 is formed on the one side of the hub so as to surround the insertion hole. The storage part has an opening part OP open to the one side, a bottom surface BT recessed in the axial direction from the opening part, and a damper side wall part 222 forming the bottom surface. The bottom surface comprises a flat surface 226, a recessed part 225 recessed in the axial direction from the flat surface and storing a head of the first spoke, and a through hole H1 formed in the recessed part into which the first spoke is inserted.SELECTED DRAWING: Figure 4
