2021 Harley-Davidson Street Glide FLHXS. The original stripped-down hot-rod bagger. With a MILWAUKEE-EIGHT 114 ENGINE. A powerful, smooth-running engine with crisp throttle response and a pure, soul-satisfying rumble. This bike is CLEAN!!! She's got Vance and Hines slip ons , and a set of highway pegs so you can kick back and enjoy the ride.
