A motorcycle, such as a scooter, includes a frame structure and arrangement of component parts which allows the footboards of the motorcycle to be lowered, enlarged and lengthened. The overall frame of a motorcycle includes a front frame portion and a rear frame portion. The front frame portion is connected to an engine of the motorcycle and the rear frame portion is connected to a transmission casing of the motorcycle. In a first embodiment, the front and rear frames are not directly connected together. In a second embodiment, the front and rear frames are connected together. By using the engine and transmission casing as components of the overall motorcycle frame in both the first and second embodiments, more flexibility is gained in the design and layout of the motorcycle's body cover and footboards. Particularly, the footboards may be lowered, enlarged and lengthened so as to improve the riding comfort of the operator and passenger of the motorcycle.
