The 2025 Harley-Davidson® Street Glide® Ultra provides a touring motorcycle designed for durability, comfort, and high-performance functionality. Engineering advancements improve long-distance riding by integrating aerodynamics, suspension, rider ergonomics, and modern technology.
Aerodynamic Design and Stability
The batwing fairing on the 2025 Harley-Davidson® Street Glide® Ultra is built to reduce wind resistance and increase stability. Computational fluid dynamics and wind-tunnel testing optimize the fairing's shape to minimize helmet buffeting at various speeds. A taller clear windshield extends four inches higher than the standard Street Glide® model, improving wind deflection while maintaining visibility.
Adjustable air vents allow riders to manage airflow, helping to regulate interior temperature based on external conditions.
Rider and Passenger Comfort
The premium two-up seat is designed to support long-distance travel. Contouring helps reduce spinal pressure by positioning the rider in a natural posture.
Storage capacity includes a King Tour-Pak® luggage carrier, large saddlebags, and fairing cubbies. These components provide 4.9 cubic feet of total storage space for secure and convenient storage solutions.
Milwaukee-Eight® 117 V-Twin Engine Performance
The Milwaukee-Eight® 117 engine delivers reliable power across diverse riding environments. A liquid-cooled cylinder head system enhances thermal efficiency, preventing overheating during extended operation in warm climates. A central radiator optimizes temperature regulation, keeping engine conditions stable during high-speed cruising.
Suspension and Ride Quality
The SHOWA® dual outboard emulsion shocks offer three inches of travel, improving damping over rough terrain. The rear suspension includes hydraulic preload adjustments, allowing quick modifications based on cargo weight or passenger presence.
Fork-mounted air deflectors reduce turbulence by managing airflow around the rider. This system improves stability, especially during high-speed travel.
Braking and Safety Features
The brakes with ABS enhance stopping power and control. The anti-lock braking system (ABS) prevents wheel lockup, maintaining traction during sudden stops or wet road conditions. The Vehicle Hold Control (VHC) stabilizes the motorcycle when stopped on an incline or decline. This feature prevents unintentional rolling and releases when the rider applies throttle. Cornering-enhanced traction control adjusts power delivery based on lean angle, improving handling in turns.
Technology and Connectivity
The 12.3-inch color TFT display powered by Skyline™ OS provides access to navigation, infotainment, and ride settings. A clear user interface allows riders to interact with features without distraction. Ride mode selection lets riders adjust performance characteristics based on road conditions. Hands-free voice recognition enables riders to control music, phone calls, and GPS without manually adjusting controls. Bluetooth® connectivity integrates with personal devices, allowing wireless audio streaming and call management.
Lighting and Visibility
The LED lighting system improves visibility and safety. An LED headlamp provides enhanced road illumination. Integrated LED turn signals and a tail light increase visibility to other motorists.
Fuel Capacity and Efficiency
The six-gallon fuel tank supports long-distance travel with fewer refueling stops. Fuel economy optimization ensures efficient engine performance without sacrificing power.
