Biltwell handlebars are precision crafted with 100% seamless 4130 chromoly. The wall thickness of our tubing is a burly .120". Classic Clubman design but in 1" diameter to fit your Gnarly Davidson. Flip 'em up or down, they are not dimpled for stock controls so you can run them in either position. These bars generally do not require changes to brake lines or cables on Evo Sportsters. Of course you may want to run shorter cables/lines/wires for a cleaner look. 1" only.
