The 2025 Harley-Davidson® Street Glide® Ultra is engineered for riders who require dependable performance, consistent stability, and practical touring functionality for extended travel. This bike is designed for two-up comfort and integrates a full range of technical components that support long-haul operation with efficiency and reliability. The motorcycle incorporates aerodynamic refinement, a large-capacity storage system, advanced safety technology, and a powertrain that delivers sufficient output for loaded touring conditions. Every primary system, from suspension to electronics, has been designed to provide predictable control and consistent rider support across varied environments. The overall configuration focuses on measurable performance benefits that align with the demands of long-distance touring.
High-Output Milwaukee-Eight® Performance
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 engine, which produces 105 horsepower and 130 foot-pounds of torque based on manufacturer data. This engine supplies the strength needed for steady acceleration during highway merging, passing situations, and steep terrain. The torque characteristics support controlled low-speed operation, which is important when navigating congested areas or maneuvering with a full passenger and packed luggage compartments. The engine achieves an estimated fuel economy of 44 miles per gallon, which provides a suitable range for uninterrupted travel intervals. Its design focuses on delivering consistent performance while maintaining the efficiency required for extended riding days.
Integrated Aerodynamic Refinements
The motorcycle incorporates a Batwing fairing developed with computational fluid dynamics and confirmed through wind tunnel testing. These methods were used to create a shape that minimizes turbulence and reduces wind buffeting. The windshield is 4 inches taller than the windshield used on the standard Street Glide® model and is engineered to decrease helmet buffeting by up to sixty percent. The improvement in wind control supports rider stability and reduces physical strain during sustained travel at highway speeds. The fairing skirt works with the lower fairing structures to maintain a balanced airflow pattern around the motorcycle, which contributes to predictable handling on open roads.
Expanded Airflow Management Adjustability
The 2025 Harley-Davidson® Street Glide® Ultra uses new fairing lowers that feature adjustable air vents designed to control airflow around the rider. These vents can be opened to increase ventilation during warm conditions or closed when additional wind protection is preferred. Fork-mounted air deflectors support the airflow system and are larger than the components found on standard Street Glide® models. Their adjustable configuration gives riders more authority over the amount of air directed toward the torso. Together these components form a wind management system that allows riders to adapt the airflow characteristics of the motorcycle to match changing conditions encountered during long-distance riding.
Touring-Focused Suspension Engineering
The suspension system uses SHOWA® dual outboard emulsion technology rear shocks. These shocks provide 3 inches of travel, which helps absorb surface irregularities across a wide range of terrain. The hydraulic preload adjustment is operated by hand and allows quick changes when carrying different passenger or luggage loads. This level of mechanical control ensures that the motorcycle maintains consistent ride height and handling quality through weight variations. The suspension system contributes to stability during long rides and ensures that both rider and passenger experience uniform comfort during extended travel periods.
Rider and Passenger Ergonomic Structure
The seat used on the 2025 Harley-Davidson® Street Glide® Ultra is designed to rotate the rider’s hips forward to reduce spine pressure during extended hours of operation. This positioning supports ergonomic alignment for riders who require a seat configuration that decreases fatigue during long touring days. The two-up seat configuration also incorporates passenger accommodations that include a structured back pad and armrests integrated into the King Tour-Pak® carrier. These features create a secure and stable seating environment for the passenger. The ergonomic design focuses on maintaining comfort and control during full-day rides without adding unnecessary complexity.
Large Capacity Storage and Protection Features
The motorcycle provides 4.9 cubic feet of combined storage across the King Tour-Pak® carrier, saddlebags, and fairing cubbies. This volume is more than twice the storage capacity of the standard Street Glide® model. The hard shell components offer durability and structured support for gear typically required on multi-day trips. Saddlebag guards are installed to protect the bodywork in the event of a low-speed tip-over. The storage system and protective elements are engineered to function consistently over long distances and with heavy use.
Functional Exterior Elements and Model Trim Options
The 2025 Harley-Davidson® Street Glide® Ultra is available in both Chrome and Black trim selections. Color options include Billiard Gray, Vivid Black, Blue Burst, Whiskey Fire with Vivid Black, and additional offerings that match specific trim configurations. A new fuel tank medallion and console inserts display the model name and are designed to complement the selected trim style. These components provide visual clarity without adding decorative complexity. The motorcycle retains standard 2025 Harley-Davidson® Street Glide® Ultra aesthetics while incorporating features that support touring needs.
Infotainment and Display System Capabilities
The motorcycle is equipped with a 12.3-inch color TFT touchscreen display that operates using the Skyline™ OS interface. This system provides infotainment functions, navigation access, and the ability to switch between four available ride modes. The screen is designed for clarity and responsive interaction, which supports efficient use while riding. A hands-free voice recognition system allows riders to issue navigation commands, such as locating fuel stops, through simple spoken instructions. These integrated systems provide direct access to essential information without requiring riders to remove focus from the road.
Safety Enhancements for Changing Conditions
The 2025 Harley-Davidson® Street Glide® Ultra includes a full suite of Rider Safety Enhancements that oversee traction, braking, and deceleration support. The Anti-lock Brake System prevents wheel lock during straight-line braking situations. Electronic Linked Braking distributes braking force between wheels to optimize braking performance. Traction Control reduces rear wheel spin during acceleration, and Drag Torque Slip Control manages rear wheel behavior during abrupt downshifts or quick throttle reductions. Vehicle Hold Control keeps the motorcycle stationary on inclines until the rider applies throttle. The Tire Pressure Monitoring System alerts the rider to low or high tire pressure, which is critical for maintaining consistent handling.
Cornering Enhanced Control Systems
The motorcycle includes multiple cornering-enhanced systems. Cornering ABS modifies brake force based on lean angle. Cornering Electronic Linked Braking adjusts pressure distribution between wheels during turns. Cornering Traction Control reduces excess wheel spin while leaned over. Cornering Drag Torque Slip Control monitors rear wheel behavior during downshifts in a turn. These systems work together to deliver stable performance throughout a full range of cornering situations by responding to lean angle and traction conditions with measured intervention.
Touring Prepared Utility Features
Additional features include improved fairing lowers, adjustable airflow components, hard shell storage, protective guards, and a reshaped seating configuration. The combination of these elements forms a motorcycle designed to maintain consistent control and comfort through extended travel. The structural design and system integration support long-distance touring requirements without unnecessary complexity or decorative emphasis. Every element focuses on functional touring performance that remains dependable across varying road conditions.
