Abstract: A sprocket ring has outwardly protruding spaced teeth to engage the motorcycle drive chain and an inner circular flange to interconnect with the sprocket hub. The sprocket hub has an outer circular flange to interconnect with the sprocket ring. Mating holes in the flanges receive bolts therethrough to interconnect the ring and the hub.

Abstract: A split sprocket assembly, related apparatus, and a method of mounting a sprocket to a rotatable structure, such as a drive or idler drum, are disclosed. In one embodiment, the sprocket assembly is comprised of at least three sections or segments, each of which is secured to the adjacent section or segment by a fastener, such as a tangentially-extending bolt and nut combination. The sprocket assembly includes a plurality of receivers, each for receiving a key that corresponds to a keyway formed in the rotatable structure. In one embodiment, at least one of the keyways is truncated and, thus, extends only partially across the rotatable structure in the axial direction. A key substantially identical to the truncated keyway in length and width is placed therein, such that the sprocket is prevented from traveling or nullwalkingnull along the rotatable structure.
