Abstract: A motorcycle-stance alteration kit is described. The kit includes a handlebar clamp, a fork clamp, and a footpeg extension. The handlebar clamp is formed to connect with a motorcycle's fork clamp and reposition the motorcycle's handlebar to alter a user's riding stance. The fork clamp is configured to be attached with motorcycle forks to the motorcycle's frame. The fork clamp includes a horizontal mounting surface that is formed to offset the fork's rake angle to cause the horizontal mounting surface to rest in a substantially horizontal alignment with respect to a ground surface. Finally, the footpeg extension is formed to connect with and between a motorcycle frame and footpeg. Thus, the footpeg extension effectively repositions the footpeg to alter the user's riding stance.

Abstract: A bracket attaches rigidly to the steering head tube member at the front of a motorcycle frame, so that the fork steering assembly can be relocated and pivotally attached to the front of the bracket. This bracket permits the fork steering assembly to be mounted in a new position which is ahead of, and higher, or lower than its former, manufacturer's specified position. The steering axis can be positioned such that it is tilted at a greater angle of inclination from the vertical, permitting use of longer fork tubes. The bracket permits any motorcycle to be reversibly modified to have the appearance and handling characteristics of a chopper style motorcycle. No modifications to the motorcycles frame are needed, in order to relocate the fork steering assembly. Thus, the originality and value of the motorcycle, if the owner decides to, later, revert to the original appearance, is maintained.

Abstract: This invention relates to front fork, telescoping type suspension systems for bicycles. The main focus of the invention is the brake bridge assembly, the fork crown assembly and the joinder of these assemblies to form the fork suspension. The brake bridge assembly serves two main functions: 1) it provides a stiff structural connection between the right and left telescoping struts, to reduce wheel wobble during high speed wheel impacts, and 2) it provides a structural support for the brake cable stop. The invention provides for increased stiffness and lower stresses in the brake bridge, which translates into improved directional stability for the front wheel, less displacement for the brake cable stop .(when the brake loads are applied) and improved fatigue life for the assembly. It also provides for a simpler and less expensive means for mounting the brake bridge to the fork assembly. The invention also encompasses the fork crown producing a lightweight structure with high torsional and bending rigidity.
