The 2025 Harley-Davidson® Street Glide® Ultra is engineered for two-up touring with integrated features that prioritize performance, comfort, and control over extended distances. Its design incorporates aerodynamic refinements, advanced electronic systems, and durable storage capacity, creating a touring platform intended to manage varying road conditions and long-haul demands. Every aspect, from the powertrain to the safety technologies, is configured for consistency, efficiency, and operational precision.
Milwaukee-Eight® 117 V-Twin Powertrain
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 V-Twin engine, producing 105 horsepower and 130 foot-pounds of torque. The engine is tuned to deliver steady acceleration and responsive output in multiple riding environments, maintaining its performance with a full touring load. The fuel economy is rated at 44 miles per gallon, optimizing range for extended travel between refueling intervals. Engine cooling and airflow have been refined to sustain power delivery and manage heat efficiently during prolonged operation.
Long-Distance Ergonomic Design
Rider and passenger comfort is addressed through seat and control geometry tailored for extended periods on the road. The two-up comfort seat is engineered to rotate the rider’s hips forward, helping to reduce spinal pressure. The passenger seating includes a backrest with integrated armrests for additional stability. The riding position is complemented by heated grips, enhancing control during lower temperature conditions.
Aerodynamic Fairing and Wind Protection
The 2025 Harley-Davidson® Street Glide® Ultra features the Batwing fairing, reshaped through computational fluid dynamics modeling, wind tunnel testing, and extended on-road evaluation. This design reduces helmet buffeting by up to 60 percent compared to standard Street Glide® models. A clear windshield, four inches taller than the standard variant, increases wind deflection without obstructing visibility. Adjustable fork-mounted air deflectors and fairing lowers with integrated vents allow the rider to control airflow and reduce fatigue over longer durations. The fairing skirt, designed to work in conjunction with these components, streamlines wind management and visual continuity.
Integrated Storage Solutions
The model includes the King Tour-Pak® luggage carrier with a robust passenger back pad and armrests. Combined with the saddlebags and fairing-mounted storage cubbies, the total capacity reaches 4.9 cubic feet, more than double that of a standard Street Glide®. All luggage components feature hard-shell construction for durability and security. Saddlebag guards are fitted and finished to match the bike, providing impact protection in the event of a tip-over.
Suspension and Ride Management
The rear suspension uses SHOWA® dual outboard emulsion technology shocks with three inches of travel. The setup is designed for consistent damping under variable loads and surface conditions. Hydraulic preload adjustment is managed through a hand-operated remote, allowing quick changes without the need for tools. Suspension stability is enhanced by aerodynamic components, including the fairing lowers, fork-mounted air deflectors, and fairing skirt, each contributing to predictable handling characteristics.
Digital Systems and Infotainment
A 12.3-inch full-color TFT display with Skyline™ OS serves as the central control interface. This system provides access to infotainment, navigation, and ride mode selection. The touch-sensitive screen is engineered for visibility under a wide range of lighting conditions. Built-in navigation can be operated through a hands-free voice recognition system, enabling the rider to execute commands such as locating fuel stations. The integrated audio system delivers 200 watts of output for clear communication and media playback.
Configurable Ride Modes
The motorcycle is equipped with multiple ride modes that adjust throttle response, braking distribution, and traction management according to rider preference and road conditions. These modes are selectable through the TFT display, allowing on-the-fly adaptation without compromising stability.
Rider Safety Enhancements
The 2025 Harley-Davidson® Street Glide® Ultra incorporates the Harley-Davidson® Rider Safety Enhancements package, a network of electronic systems designed to optimize stability, braking, and traction. The anti-lock brake system (ABS) prevents wheel lockup during straight-line emergency braking. Electronic Linked Braking (ELB) proportionally applies braking force to both wheels, improving stability during deceleration. Traction Control System (TCS) limits rear wheel slip under acceleration, while the Drag-Torque Slip Control System (DSCS) reduces excessive rear-wheel slip during abrupt throttle reductions or downshifts on low-traction surfaces.
Cornering-Optimized Control Systems
Several safety functions operate with cornering-enhanced capabilities. Cornering ABS (C-ABS) adjusts braking pressure based on lean angle to maintain stability through turns. Cornering Electronic Linked Braking (C-ELB) modifies brake force distribution between the front and rear wheels when leaned, aiding in maintaining the intended line. Cornering Traction Control System (C-TCS) controls wheel spin during both straight-line and leaned acceleration. Cornering Drag-Torque Slip Control System (C-DSCS) manages deceleration stability when downshifting or rolling off the throttle in curves, particularly on wet or unstable surfaces.
Vehicle Hold and Tire Pressure Monitoring
Vehicle Hold Control (VHC) maintains brake engagement on inclines or declines after the rider releases the brake lever or pedal, allowing a controlled start without rollback. This system is intended for temporary holding at stops rather than long-term parking. The Tire Pressure Monitoring System (TPMS) provides alerts through the display when tire pressure is outside optimal ranges, supporting consistent handling and extending tire service life.
Functional Styling and Trim Options
The 2025 Harley-Davidson® Street Glide® Ultra is offered in Chrome and Black trim configurations, with multiple color options including Billiard Gray, Vivid Black, Blue Burst, Whiskey Fire/Vivid Black, Iron Horse Metallic/Vivid Black, and Mystic Shift. A redesigned fuel tank medallion and console inserts match the selected trim, displaying the model name. All finishes and detailing are engineered for durability in touring conditions while retaining clear identification of the model’s specifications.
Touring Capability with Integrated Technology and Control
The combination of the Milwaukee-Eight® 117 powertrain, adjustable suspension, aerodynamic refinements, and a comprehensive electronics package results in a touring motorcycle configured for sustained operation over extended distances. The TFT-based Skyline™ OS interface consolidates entertainment, navigation, and ride customization in a single, accessible format. Advanced braking and traction systems operate in both upright and leaned conditions, providing control across a wide range of road surfaces. Storage capacity and passenger accommodations are designed to maintain comfort without compromising performance or handling.
