2017 Harley-Davidson FLHXS Street Glide Special
About the 2017 Harley-Davidson FLHXS Street Glide Special
The 2017 Street Glide Special marks a pivotal year for Harley-Davidson's top-selling bagger, introducing the all-new Milwaukee-Eight 107 engine. This model year transitioned away from the Twin Cam 103, offering significantly improved heat management, reduced vibration, and 10% more torque. The 'Special' trim differentiates itself through premium infotainment, standard ABS, and a factory-painted inner fairing, though it retains the traditional chrome engine finishes and standard saddlebags that were later replaced by blacked-out styling in 2018.
What Makes This Trim Special
- Boom! Box 6.5GT Infotainment — Features a 6.5-inch color touchscreen with integrated GPS navigation and Bluetooth connectivity, replacing the 4.3-inch non-touch unit on the standard model.
- Reflex Linked Brakes with ABS — Anti-lock braking system that electronically links front and rear brakes is standard on the Special; it was an optional upgrade on the standard FLHX.
- Smart Security System — Includes a hands-free security fob that automatically arms/disarms the vehicle's electronic security functions based on proximity.
- Gloss Black Inner Fairing — The inner fairing is finished in premium gloss black paint rather than the textured matte plastic found on the standard model.
- Enforcer Cast Aluminum Wheels — Features a 19-inch front and 16-inch rear Enforcer wheel set with a machined finish.
Likely but unverified:
- Chrome Engine Finishes — Unlike later 'Special' models (2018+), the 2017 FLHXS features a chrome-heavy powertrain and exhaust system.
