The Biltwell Keystone bars are one of our Top-Selling handlebars here at Get Lowered. They look great on almost any Harley Sportster XL models, or other slimmer bikes such as British or Japanese choppers with a 1" clamping area. They're constructed from 1" O.D. tubing with 0.120 wall thickness. All bends are created with internal mandrels on a CNC bender to reduce flat spots and all welded joints are precision mitered and TIG welded. Select the Dimpled version for most Stock OEM replacements or the Non-dimpled (Smooth) version for custom aftermarket applications.
