Abstract: A swing arm assembly for use with a motorcycle and including provisions which aid in the replacement of a drive belt. The swing arm includes two side members for supporting the rear wheel of the motorcycle and a connecting member which is pivotally attached to the main frame of the motorcycle using at least one connection bolt. The drive belt is positioned between the two side members and around the connecting member. The connecting member is attached to the side members and includes a removable spacer. The spacer may be selectively removed so that a gap is provided through the connecting member and between the two side members. The gap is sized to accommodate the passage of the drive belt, during its replacement. The spacer is preferably secured to the connecting member by the connection bolt.
