Construction: 7/8-inch 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. These handlebars are not dimpled because 7/8-inch O.D. handlebars do not fit stock Harley hand controls.
Fitment: At 7 inches from center of clamping area to center of the top bend, Frisco bars are 2 to 5 inches taller than most stock handlebars. The nearly flat back sweep creates a T-Bar look and feel without making changes to your trees or risers. Depending on the height of the bars you're replacing, longer brake lines, clutch and throttle cables and/or switch wiring may be necessary.
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.
