ABSTRACT:
Improved handlebars for bicycles, motorcycles, power vehicles such as two wheeled power vehicles and all terrain vehicles, including off road bicycles, motorcycles, dirt bikes, all terrain bicycles, all terrain vehicles and jet skis. The improved handlebars eliminate the need of a crossbar by increasing the diameter and sidewall thickness of the central section of the handlebars, and diminish the stiffness of the handlebars by decreasing the respective diameter and sidewall thickness of the two grip sections of the handlebars. The improved handlebars are incorporated with unique tapered sections and are manufactured through a process that causes greater amount of metal to be located in the widest diameter section of the handlebars, and smaller amount of metal to be located in the narrowest diameter section of the handlebars. The handlebars have a longer unsupported span than conventional handlebars, thereby providing more cushioning strength and greater steering control. The strength of the handlebar is reinforced due to the increased diameter and thickened sidewall of said central section, and the stiffness of said handlebar is reduced due to the decreased diameters and thinned sidewalls of said first and second grip sections.
