Abstract
A motorcycle includes an extended and lower frame arrangement, a front wheel coupled to the extended and lower frame arrangement via a front wheel extension member to frontwardly extend a distance between the extended and lower frame arrangement and the front wheel, a rear wheel coupled to the extended and lower frame arrangement via a widen hub assembly to rearwardly extend a distance between the extended and lower frame arrangement and the rear wheel, such that the front wheel and the rear wheel are shifted far from the extended and lowered frame arrangement to lengthen a distance between the front wheel and the rear wheel so as to further lower a center of gravity of the motorcycle.
Claims20
A motorcycle, comprising:
- an extended and lowered frame arrangement which comprises a supporting frame having a front portion, a rear portion, and a floorboard extended between said front portion and said rear portion, and an engine mounting frame extended from said supporting frame, wherein an orientation of said floorboard is lower than that of said front portion and said rear portion;
- a steering assembly operatively mounted at said front portion of said supporting frame;
- a front wheel assembly which comprises two spaced apart front forks, a front wheel rotatably coupled between said front forks, and a front wheel extension member having a rear portion coupled at a bottom portion of said steering assembly and a front portion coupled at said front forks to frontwardly extend a distance between said front portion of said supporting frame and said front wheel;
- a power generator which comprises an engine, said engine mounting frame of said extended and lowered frame arrangement securely supporting said engine underneath said rear portion of said supporting frame to lower a center of gravity of said supporting frame;
- a rear wheel assembly which comprises a rear wheel supported away from said rear portion of said supporting frame and driven to rotate by said engine, wherein said rear wheel is shifted rearward until a center of said rear wheel is located behind a rear end of said supporting frame to lengthen a distance between said rear portion of said supporting frame and said rear wheel, wherein said front wheel and said rear wheel are both shifted far from said supporting frame to lengthen a distance between said front wheel and said rear wheel so as to lower a center of gravity of said extended and lowered frame arrangement and said power generator;
- a suspension assembly comprising at least a suspension arm extended from said supporting frame to said rear wheel assembly for absorbing vibration from said rear wheel and said engine;
- a seat frame, which is mounted above said rear portion of said supporting frame, comprising a seat support upwardly extended from said rear portion of said supporting frame and a seat pad provided on said seat support, wherein said seat support has a generally U-shaped configuration mounted on said rear portion of said supporting frame to support said seat support thereon;
- and
- a power assembly, provided on said floorboard of said supporting frame and operatively linked to said engine as a power supply, being a gas tank assembly which comprises a gas tank supported on said floorboard of said supporting frame and operatively linked to said engine as a fuel supply and a gas tank protection frame extended from said floorboard to form a protection cavity to receive said gas tank therein so as to protect said gas tank, wherein said gas tank protection frame, having a grid-like configuration, has an upper grid cover covering on top of said gas tank while a space is formed between a top side of said gas tank and a bottom side of said grid cover.
