A custom bar can also be made from your specifications. Measurements alone define where the ends are, but we need to know the shape of the bar also. A discussion of your bike will help. Davidsons have 1 diameter handlebars. Please be specific.
Springers are wider.
For all Japanese and European bikes we need to know exactly where the knurling is located. Please be specific about diameter, knurling, late Harley dimples for wiring, holes and any unusual specifications. I measure centers as the flat mounting area between bends. If you stood a handlebar on the floor and measured to the highest point, that would be the height. Zero degree pullback would be a flat bar and ninety degrees would point straight back.
