Motorcycle steering using compound leverage

Abstract

A compound lever motorcycle steering mechanism comprised of an upper and lower lever parallel and adjacent to one another. With one lever being attached at a right angle to a shaft inside a collar or bearing to form a second axis adjacent to, and parallel with the axis where the front forks of the motorcycle are attached by another shaft to the main frame of the motorcycle. Said lever also having an attachment for a handlebar or set of handlebars, as well as a second shaft, pin, or bolt protruding at a right angle from the lever, and into a longitudinal slot, opening, or channel in the second lever, of a width only minimally larger than the diameter of said protruding shaft to sufficiently allow fore and aft movement of same through the slotted second shaft, which is rigidly attached or affixed to the front forks.

1 . A motorcycle comprising:
 a frame;   a wheel rotatably attached to the frame;   a handlebar; rotatably attached to the frame; and   a steering system including a first elongated member coupled to the handlebar, the elongated member rotatably coupled to the frame along a first axis of rotation and a second elongated member rotatably coupled to the frame along a second axis of rotation, the second elongated member coupled to the wheel, the second elongated member slidably engaged with the first elongated member.   
   
   
       2 . The motorcycle of  claim 1  wherein the first elongated member is shorter than the second elongated member. 
   
   
       3 . The motorcycle of  claim 1  wherein the first elongated member includes a steering stem rotatably coupled within a headstock, the headstock coupled to the frame. 
   
   
       4 . The motorcycle of  claim 1  wherein the first elongated member is slidably engaged with the second elongated member through a pin fixedly coupled with the first elongated member and a bearing slidably coupled to the second elongated member, the pin fixedly coupled to the bearing. 
   
   
       5 . The motorcycle of  claim 4  wherein the pin is fixedly coupled to the first elongated member a distance from the first axis of rotation and the bearing is slidably coupled to the second elongated member at least a second distance from the second axis of rotation, the first distance being smaller then the second distance. 
   
   
       6 . The motorcycle of  claim 1  wherein the first elongated member extends from the frame in a first plane and the second elongated member extends from the frame in a second plane, the second plane being parallel to the first plane. 
   
   
       7 . The motorcycle of  claim 1  wherein the second elongated member is coupled to the wheel through a first fork and a second fork. 
   
   
       8 . A steering system for a motorcycle, the motorcycle including a wheel, a frame, and a handlebar, the system comprising:
 a first elongated member coupled to the handlebar, the first elongated member rotatably coupled to the frame along a first axis of rotation and a second elongated member rotatably coupled to the frame along a second axis of rotation, the second elongated member coupled to the wheel, the second elongated member slidably engaged with the first elongated member.   
   
   
       9 . (canceled) 
   
   
       10 . The steering system of  claim 8  wherein the first elongated member is shorter than the second elongated member. 
   
   
       11 . The steering system of  claim 8  wherein the first elongated member includes a steering stem rotatably coupled within a headstock, the headstock coupled to the frame. 
   
   
       12 . The steering system of  claim 8  wherein the second elongated member includes a steering stem rotatably coupled within a headstock, the headstock coupled to the frame. 
   
   
       13 . The steering system of  claim 8  wherein the first elongated member is slidably engaged with the second elongated member through a pin fixedly coupled with the first elongated member and a bearing slidably coupled to the second elongated member, the pin fixedly coupled to the bearing. 
   
   
       14 . The steering system of  claim 13  wherein pin is fixedly coupled to the first elongated member a first distance from the first axis of rotation and the bearing is slidably coupled to the second elongated member at least a second distance from the second axis of rotation, the first distance being smaller than the second distance. 
   
   
       15 . The steering system of  claim 8  wherein the first elongated member extends from the frame in a first plane and the second elongated member extends from the frame in a second plane, the second plane being parallel to the first plane. 
   
   
       16 . The steering system of  claim 8  wherein the second elongated member is coupled to the wheel through a first fork and a second fork. 
   
   
       17 . A method of steering a motorcycle, the motorcycle including a wheel, a frame, and a handlebar, the wheel rotatably coupled to the frame, the method comprising:
 coupling handlebar to a first elongated member rotatably coupled to the frame along a first axis of rotation;   coupling the wheel to a second elongated member rotatably coupled to the frame along a second axis of rotation;   receiving a force imparted upon the handlebar to provide a first rotational force to cause a first rotation of a first elongated member along the first axis of rotation; and   transferring the first rotational force to a second elongated member to cause a second rotation of the second elongated member along a second axis of rotation thereby turning the wheel.
