The 2025 Harley-Davidson® Street Glide® Ultra is configured as a long-distance touring motorcycle with a clear focus on two-up capability, mechanical consistency, and advanced rider-support technologies. Its design structure reflects a combination of aerodynamic refinement, enhanced storage capacity, and a range of high-function components intended to maintain stability and comfort over extended miles. The platform incorporates updates to airflow management, chassis features, infotainment systems, and safety technologies, all intended to support predictable operation across varied environments. Every element of the 2025 Harley-Davidson® Street Glide® Ultra is positioned to deliver measurable benefits in power, rider ergonomics, wind control, and control system intervention, with each component working together to support extended travel.
Powertrain Output and Engine Characteristics
The Milwaukee-Eight® 117 V-Twin powers the 2025 Harley-Davidson® Street Glide® Ultra with an output of 105 horsepower and 130 ft lb of torque. This configuration supplies consistent acceleration for merging, passing, and steady highway pacing even when the motorcycle is carrying a full passenger and luggage load. The torque curve supports strong response in the midrange, allowing controlled and predictable power delivery. A fuel economy rating of 44 mpg contributes to longer intervals between refueling stops, which is important for long-distance travel. The engine’s air and oil cooling setup is designed to maintain performance in various temperature conditions without compromising stability or output.
Ergonomic Configuration for Long-Distance Travel
Rider and passenger comfort are supported by a seating design created specifically for long-duration operation. The two-up seat is shaped to rotate the rider’s hips forward in order to reduce spinal strain and maintain a balanced riding posture. This adjustment also allows the rider to maintain a firm and steady control position over extended periods. The handlebars, foot placement, and grip reach work with the seat to minimize unnecessary movement and support a consistent riding form. Heated grips are included as standard equipment to sustain hand comfort in cooler climates and variable weather. With a laden seat height of 26.9 inches, the 2025 Harley-Davidson® Street Glide® Ultra remains accessible while maintaining a secure low stance for confident low-speed positioning.
Aerodynamic Structure and Wind Management Systems
The 2025 Harley-Davidson® Street Glide® Ultra features a Batwing fairing reshaped through computational fluid dynamics and wind tunnel testing to provide measured improvements in airflow routing. The taller clear windshield is 4 inches higher than the standard Street Glide® version and reduces helmet buffeting by up to 60 percent. This reduction helps the rider maintain stability, especially during long highway intervals where consistent airflow control is important. Additional components contribute to the aerodynamic function, including the redesigned fairing skirt, air deflectors, and fairing lowers.
Fork-mounted air deflectors are larger than the components used on standard models and can be adjusted to divert airflow away from the torso or opened to increase cooling airflow directly toward the rider. The new fairing lowers include adjustable vents that complement the deflectors by adding another layer of airflow control near the lower frame area. These systems function together to maintain steady air movement on the rider’s upper and lower body while reducing turbulence in key contact zones. This combination improves overall comfort and supports consistent handling during long-distance travel.
Suspension, Ride Quality, and Chassis Behavior
SHOWA® dual outboard emulsion rear shocks provide three inches of travel and are equipped with a remote hydraulic preload adjuster. Riders can make adjustments by hand to accommodate changes in passenger weight or luggage load without additional tools. This configuration allows the suspension to maintain consistent sag and ride balance across different touring conditions. The suspension setup supports predictable behavior when entering corners, traveling over uneven road surfaces, or navigating varying highway textures.
Storage Capacity and Touring Utility Design
The 2025 Harley-Davidson® Street Glide® Ultra includes an extensive luggage system designed for practical long-haul use. The King Tour-Pak® luggage carrier comes standard and provides both structural storage capacity and a passenger back pad with armrests for additional comfort. When combined with the saddlebags and fairing cubbies, the total capacity reaches 4.9 cubic feet, which is more than double the storage volume available on a standard Street Glide®. The hard-shell construction of the storage units supports protection of stored items while maintaining the motorcycle’s structural integrity. Saddlebag guards, color-matched to the selected trim option, offer bodywork protection in the event of a tip-over. The tank features a model-specific medallion available in chrome or black, with console inserts displaying the Street Glide® Ultra name to reinforce model identification.
Infotainment System and Integrated Display Technology
A 12.3-inch color TFT touchscreen with the Skyline™ OS serves as the central interface for infotainment and system configuration. This display provides access to embedded navigation, ride mode selection, media management, and system settings through a clear and responsive layout. The hands-free voice recognition system allows the rider to use spoken commands such as “Find me a gas station” to manage navigation input without removing hands from the controls. The system is designed to maintain readability in varied lighting and supports swift interaction for essential functions.
Rider Safety Enhancements and Stability Technologies
The 2025 Harley-Davidson® Street Glide® Ultra incorporates a comprehensive suite of safety technologies designed to support traction, braking control, and stability management. The Anti-lock Brake System prevents wheel lock during hard straight-line braking situations and supports control during rapid deceleration. Electronic Linked Braking distributes braking effort between the front and rear wheels under certain conditions and adjusts the linking effect at lower speeds to maintain familiarity and smooth control.
The Traction Control System moderates rear-wheel spin during acceleration in low-traction situations. The Drag-Torque Slip Control System helps reduce excessive rear-wheel slip caused by abrupt downshifts or sudden throttle reductions, particularly in wet or slick environments. Vehicle Hold Control keeps the motorcycle stationary on an incline or decline after a brief squeeze of the brake lever, which assists with smooth and controlled hill starts.
Cornering-enhanced systems modify their behavior based on lean angle. Cornering ABS adjusts brake pressure requirements through a turn. Cornering Electronic Linked Braking modifies front and rear brake pressure proportioning. Cornering Traction Control manages wheel spin during cornering acceleration. Cornering Drag-Torque Slip Control reduces the risk of rear-wheel slip during deceleration while leaned over. The Tire Pressure Monitoring System provides alerts on the display when tire pressure is outside recommended levels, supporting longevity and consistent handling performance.
Trim Options and Color Configurations
The motorcycle is offered in Chrome and Black trims with distinct color selections. Chrome trim is available in Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire with Vivid Black. Black trim is offered in those colors along with Iron Horse Metallic with Vivid Black and Mystic Shift.
