A motorcycle has a final drive, including a flexible drive member, such as a chain or a belt, that extends between the drive pulley and the driven pulley. A belt retention member is positioned proximate a forward portion of the final drive to reduce the likelihood of the belt skipping free of the drive pulley. The belt retention member preferably includes an upper belt retention portion and a lower belt retention portion. Preferably, the upper drive retention portion is positioned further forward relative to the lower belt retention portion such that the upper portion is moved more forward relative to an axis of rotation of the pulley. In this manner, the belt retention member allows more slack to be thrown during rapid acceleration from a decelerated state in the illustrated motorcycle.
