Claim 1
Independent Claim
146 words
A motorcycle wheel comprising (a) a hub having a periphery, the hub including (1) peripherally spaced, radially outwardly extending lugs along the periphery of the hub, the lugs defining bores, (b) an integral wheel body including (1) a central ring surrounding the periphery of the hub, the central ring and the hub periphery defining air flow passages disposed radially between the central ring and the periphery of the hub, and (2) a plurality of spokes radiating from the central ring, respective ones of the lugs being disposed between adjacent ones of the spokes, and each spoke having two stiffened longitudinal edge portions, imaginary longitudinal extensions of adjacent ones of the stiffened edge portions of the adjacent spokes intersecting in the bores of the lugs disposed therebetween, and (c) fastening elements extending through the bores and affixing the central ring of the wheel body to the hub.
