A modern interpretation on the classic dirt-bike handlebar, built with quality materials and smart ergonomics to fit and feel great on high-performance Harleys of all kinds. These handlebars are constructed with seamless CNC mandrel bent 0.120” wall 4130 chromoly tubes. Available in two styles: Smooth and TBW with Insert. Smooth bars are for custom applications and have no slots, dimples or castellated ends. TBW w/ insert handlebars work with regular, cable-operated throttles, and if you remove the black end plug it will accept Harley's Throttle-By-Wire control module. TBW bars have slots on each side for stock H-D hand controls and an exit slot in the center for internal wiring.
