The 2025 Harley-Davidson® Street Glide® Ultra is engineered as a two-up touring motorcycle with advanced performance, rider-focused ergonomics, and a complete suite of technology and safety systems. Every aspect has been designed to support long-distance travel with precision and confidence. Its combination of power, aerodynamic improvements, integrated storage, and modern electronic systems makes it the most capable Harley-Davidson® Street Glide® model for riders who require functionality over extended miles.
Engine Performance and Efficiency
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 V-Twin engine. This engine produces 105 horsepower and 130 foot-pounds of torque, delivering reliable output in a wide range of riding conditions. Despite its high-performance capabilities, the model achieves a fuel economy of 44 miles per gallon, balancing output with efficiency for extended journeys.
The engine’s design emphasizes consistent torque delivery, offering strong mid-range response that benefits riders carrying passengers and luggage. Combined with a six-speed transmission, the 2025 Harley-Davidson® Street Glide® Ultra ensures seamless gear transitions that complement the engine’s broad powerband.
Aerodynamic Improvements and Wind Protection
The 2025 Harley-Davidson® Street Glide® Ultra introduces refined aerodynamics developed using computational fluid dynamics and wind tunnel testing. The redesigned Batwing fairing reduces turbulence and helmet buffeting by up to 60 percent compared to standard Harley-Davidson® Street Glide® models.
A clear windshield, four inches taller than the standard configuration, further improves wind deflection for both rider and passenger. Complementing the fairing are fork-mounted air deflectors that can be adjusted to direct airflow around the rider or increase ventilation to the torso in warm conditions. New fairing lowers with adjustable vents integrate with the skirt to improve airflow control and reduce fatigue over long distances.
Ergonomics and Rider Comfort
Long-distance ergonomics have been addressed with a newly designed two-up comfort seat. The seat rotates the rider’s hips forward to reduce spinal pressure, supporting correct posture on extended trips. Heated hand grips are included as standard, providing consistent control during cooler conditions.
Passenger comfort is equally prioritized. The King Tour-Pak® luggage carrier is equipped with a padded backrest and armrests, offering stable support on long journeys. Combined with the rider-focused seat design, these features enhance the Ultra’s capacity for sustained two-up touring.
Suspension performance contributes significantly to overall comfort. The rear suspension uses SHOWA® dual outboard emulsion technology shocks with three inches of travel. These shocks feature remote hydraulic preload adjustment that can be completed by hand, allowing riders to adapt suspension settings quickly to changing load or road conditions.
Touring Storage Capacity
The 2025 Harley-Davidson® Street Glide® Ultra delivers extensive storage capacity with a total of 4.9 cubic feet. This includes the standard King Tour-Pak® luggage carrier, large saddlebags, and fairing cubbies. The capacity is more than double that of a standard Harley-Davidson® Street Glide®, offering space for gear, personal items, and touring necessities.
The luggage system is designed with durability and protection in mind. The hard-shell construction secures contents against weather exposure while saddlebag guards protect both storage units and bodywork in case of a tip-over. Additional details such as chrome or black tank medallions and uniquely styled console inserts reinforce the model’s premium touring design while maintaining functional durability.
Suspension, Stability, and Handling
Handling on the 2025 Harley-Davidson® Street Glide® Ultra is enhanced by multiple design choices that optimize stability and rider control. The improved suspension system not only absorbs road imperfections but also delivers consistent responsiveness in cornering situations. With three inches of travel, the SHOWA® shocks reduce vibration transfer, keeping the motorcycle composed across variable surfaces.
Aerodynamic stability is reinforced by the integration of fork-mounted air deflectors and new fairing lowers, which reduce turbulence around the rider and improve airflow. The fairing skirt coordinates with these elements to enhance visual integration while optimizing wind management.
Advanced Infotainment and Connectivity
A central feature of the 2025 Harley-Davidson® Street Glide® Ultra is the Skyline™ OS infotainment system. The motorcycle is equipped with a 12.3-inch full-color TFT touchscreen display, the largest available on a Harley-Davidson® touring model. This screen provides access to navigation, audio, ride modes, and connectivity functions in a clear and easily operable format.
The system integrates hands-free voice recognition, enabling commands such as locating gas stations without manual input. Apple CarPlay® compatibility is included, providing access to personal apps and media in a controlled environment. Audio output is powered through a robust 200-watt system, ensuring clear sound delivery even at highway speeds. The integration of multiple functions into a single, user-friendly display enhances rider convenience while reducing distraction.
Safety and Rider Support Systems
The 2025 Harley-Davidson® Street Glide® Ultra incorporates an extensive suite of safety technologies under Rider Safety Enhancements. Each system is designed to assist the rider in maintaining stability and control across a variety of conditions.
The Anti-lock Brake System prevents wheel lock during emergency stops, while Electronic Linked Braking balances braking force between the front and rear wheels for improved stopping performance. The Traction Control System reduces rear-wheel spin during acceleration, enhancing confidence on low-grip surfaces. Drag-Torque Slip Control prevents excessive slip or lock-up during abrupt downshifts or throttle roll-offs, particularly in wet conditions.
Vehicle Hold Control prevents rollback on inclines or declines by holding brake pressure until throttle is applied. The Tire Pressure Monitoring System alerts the rider to abnormal tire pressures, supporting consistent handling and tire longevity.
Cornering-enhanced technologies further expand control. Cornering ABS, Electronic Linked Braking, Traction Control, and Drag-Torque Slip Control adjust performance based on lean angle, optimizing grip and stability during cornering maneuvers. These integrated systems operate seamlessly, allowing the motorcycle to adapt to both linear and angled riding situations with improved precision.
