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 radius's. For exact measurements, please click the Specifications icon in the photo album. Fitment: Biltwell Trackers are even lower than most original equipment handlebars, so retro fitment with stock cables and wiring is generally a snap. Note: as Tracker bars are slightly wider than stock bars, please consider turning angle and tank size/mounting before ordering. 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.
