Abstract
A motorcycle includes a frame and a flexible drive member. The frame is provided with an aperture. An engine is attached to the frame and is configured to selectively rotate a drive sprocket. A driven sprocket is attached to a rear wheel. A flexible drive member operably couples the drive sprocket and the driven sprocket and, in doing so, passes through the aperture in the frame. Methods of manufacturing a motorcycle are also provided.
