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.

The disclosure relates to improved fastening mechanisms having both sufficient stiffness to bear a load and the ability to fit securely on a wide-range of sizes and shapes of tubing, including tapered tubing. Embodiments include a fastening mechanism with a first body part having a first inner surface, and a second body part having a second inner surface. A first fastening set may be disposed at a first end of the first and second body parts. A second fastening set may be disposed at a second end of the first and second body parts. The first and second fastening sets may be capable of securing the first and second body parts about a central tube, which may have tapered dimensions. The first inner surface and the second inner surface may each have a first subsurface and a second subsurface, the first subsurfaces may have a first contour, the second subsurfaces may have a second contour, and the first contour may fit a different size and shape of tubing than the second contour.
