RELATED APPLICATIONS 
     The present application is a divisional application of parent U.S. application Ser. No. 08/740,990, filed Nov. 5, 1996, now U.S. Pat. No. 5,829,316 issued on Nov. 3, 1998 and co-owned herewith, relied upon for priority and incorporated herein by reference for all legitimate purposes. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of handlebar mounts for motorcycles or comparable vehicles. More particularly, the present invention relates to the field of means for mounting a handlebar on existing stock handlebar clamps of motorcycles or comparable vehicles. 
     2. Description of the Prior Art 
     One of the problems with stock handlebar clamps is that they are usually constructed for clamping a stock handlebar, and therefore the rider cannot change the stock handlebar to a particular handlebar. Specifically, aftermarket manufacturers of handlebars often require special handlebar clamps for clamping their larger diameter handlebar to the motorcycle or comparable vehicle. In the past, any motorcycle or bike that had solid mounts (as opposed to rubber-mounted bar clamps) required a special handlebar clamp. 
     It is desirable to have a very efficient and also very effective design and construction of universal mounts for securing a particular handlebar to the motorcycle, where the universal mounts are interlocked with the stock handlebar clamps. 
     SUMMARY OF THE INVENTION 
     The present invention is an assembly of sets of universal mounts for interlocking with stock handlebar clamps to secure and clamp a particular handlebar to a motorcycle or comparable vehicles. 
     The present invention clamp-on-a-clamp concept is a simple and easy way to mount larger diameter handlebars to motorcycles or comparable vehicles. Each set of universal handlebar mounts is interlocked with the stock handlebar clamps. Each set of the universal mounts comprises an upper mount and a lower mount. Each mount has a semi-cylindrical groove, where a larger diameter handlebar is respectively fitted between the semi-cylindrical grooves of the upper and lower mounts. Each lower mount has a protruding arch which is respectively positioned within the respective stock handlebar clamp, and thereby interlocks with the respective stock handlebar clamp. 
     It is therefore an object of the present invention to provide an assembly of universal mounts which can be interlocked with stock handlebar clamps or the like for securing and clamping a particular handlebar, for example, a larger diameter handlebar, to a motorcycle or comparable vehicles. 
     It is a further object of the present invention to provide at least one universal mount which includes an upper portion and a lower portion and can be interlocked with stock handlebar clamps or the like for securing and clamping a particular handlebar, for example, a larger diameter handlebar, to a motorcycle or comparable vehicles. 
     Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     Referring to FIG. 1, there is depicted a particular handlebar 2 for a motorcycle or comparable vehicle 3 partially and schematically depicted in FIG. 1 and two sets of universal mounts 10 and 12 of the present invention, where the handlebar 2 is mounted by the two sets of the universal mounts 10 and 12 to stock handlebar clamps 11 and 13 partially and schematically shown in phantom lines in FIGS. 1 and 2 of a motorcycle or comparable vehicle. Since both sets of the universal mounts 10 and 12 are identical, only one set of the universal mount will be described in detail below. 
     Referring to FIG. 2, the universal mount 10 comprises a generally rectangular shaped lower mount 14 and a generally rectangular shaped upper mount 15. Now referring to FIGS. 2 and 4, the lower mount 14 has a proximal side 16, a distal side 18, two pairs of spaced apart opposite vertical interior bores 20 and 22 which extend through from the proximal side 16 to the distal side 18, and a transverse semi-cylindrical or tubular shaped groove 24 which is adjacent to the proximal side 16. Each vertical bore 20 has a countersunk cavity 26 which extends partially down within the interior bore 20 and is located adjacent to the proximal side 16 of the lower mount 14. Each vertical bore 22 has inner threads 28 therein. A protruding arch or boss shaped portion 30 is integrally attached to the distal side 18 of the lower mount 14 and located between the two vertical bores 20. The size of the protruding shaped arch portion 30 is approximately half the width W of the lower mount 14.
