Construction: 7/8" O.D. x 0.120"; wall seamless 4130 chromoly tubing. All bends are created with internal mandrels on a CNC bender to reduce flat spots in the radiuses, and all welded joints are precision mitered and TIG welded.
Fitment: Mild 13-degree back sweep is especially comfortable on bikes with shorter backbones (Sportsters, British and Japanese choppers, for instance) For this reason, the Keystone is one of our most popular handlebars; it looks and fits great on damn near everything.
A Few Words on Knurling: We don't knurl our bars because doing so reduces the surface area where the handlebar makes contact with the risers, thereby compromising clamping power. Stock and aftermarket steel risers commonly found on cruisers and custom big twins have a material density 4 times greater than aluminum. This density doesn't let knurling bite into the riser material, which in turn compromises clamping strength.
