%20(1).png)
The 2025 Harley-Davidson® Street Glide® Ultra is a motorcycle engineered for extended touring with a full passenger load. It builds upon the Harley-Davidson® Street Glide® platform by increasing comfort, optimizing airflow, expanding storage capacity, and integrating safety systems designed to handle variable conditions. This model exists to serve riders who cover long distances across varying terrains while requiring sustained control, support, and convenience from their machine.
Engine Specification and Road Performance
At its core, the 2025 Harley-Davidson® Street Glide® Ultra uses the Milwaukee-Eight® 117 engine. This air- and oil-cooled V-twin produces 105 horsepower and 130 ft-lb of torque. The powerband favors low-end torque to maintain consistent propulsion during loaded travel or incline transitions. Fuel economy is estimated at 44 mpg, which allows for fewer interruptions during long rides.
The throttle mapping and engine management system support predictable input under load, which is essential for highway cruising and transitional road surfaces. Heat management is aided by engine cooling fins and oil routing that distribute thermal buildup away from the rider compartment.
Aerodynamic Redesign with Utility Focus
The redesigned Batwing fairing is shaped using computational fluid dynamics and wind tunnel data. The new clear windshield stands four inches taller than the standard version on base Harley-Davidson® Street Glide® models. This increase in height improves air deflection and reduces helmet buffeting by up to sixty percent, as verified during road testing.
Adjustable fork-mounted deflectors, paired with redesigned fairing lowers, allow the rider to control airflow in real-time. These components work in conjunction with a fairing skirt to maintain balanced pressure across the rider’s chest and shoulders. The new setup decreases rider fatigue during high-speed sections by reducing the need for constant repositioning.
Riding Position and Ergonomic Comfort
The seat design rotates the rider’s hips slightly forward, which supports the natural curve of the spine and reduces lower back pressure. The passenger seat is wide and padded, supported by a King Tour-Pak® system that includes an integrated backrest with armrests. Heated grips are standard and assist in maintaining rider dexterity in colder weather or elevated terrain.
Suspension is managed by SHOWA® dual outboard emulsion shocks with three inches of travel. A remote hydraulic preload adjuster can be activated by hand, allowing for load-based changes without tools. The front end is designed to match rear compliance, giving the chassis a uniform response across weight shifts, braking, and road imperfections.
Storage Volume and Luggage Integration
Touring riders require equipment flexibility. The 2025 Harley-Davidson® Street Glide® Ultra is fitted with 4.9 cubic feet of enclosed storage volume. This includes large hard saddlebags, the King Tour-Pak top box, and fairing-mounted storage cubbies. All compartments are lockable and designed for weather resistance. Saddlebag guards are integrated to prevent panel damage in tip-over events or close-quarter maneuvering.
The top box includes a padded backrest for the passenger and provides enough space for overnight gear, travel electronics, or layered clothing. The saddlebags open with one-touch latches and are hinged to remain sealed during motion.
Display System and Software Capabilities
A 12.3-inch color TFT display sits at the center of the cockpit. It runs on the Skyline™ OS, which organizes navigation, audio, and vehicle data into a single interface. The touchscreen supports swipe and tap functions with gloved hands.
The system allows voice-based navigation commands and offers seamless transitions between ride modes. With Apple CarPlay® integration, smartphone functions can be accessed through the display for communication, route planning, or entertainment. Audio output is routed through a 200-watt amplifier capable of remaining audible through a full-face helmet and road noise.
Safety Enhancements for Touring Environments
The 2025 Harley-Davidson® Street Glide® Ultra is fitted with the brand’s full suite of Rider Safety Enhancements. These systems are designed to intervene in conditions where tire traction, braking performance, or vehicle stability is reduced.
The Anti-lock Brake System prevents wheel lock during straight-line braking and works with Electronic Linked Braking to optimize force distribution between front and rear. When braking force is light or speeds are low, the system decouples for more natural feedback.
Cornering Enhanced Anti-lock Braking adjusts braking pressure based on lean angle, reducing the chance of slideouts in mid-turn deceleration. This system is supported by Cornering Enhanced Electronic Linked Braking, which modifies braking ratios during lean.
Traction Control manages rear wheel slip under acceleration and is adjusted dynamically during cornering with the Cornering Enhanced Traction Control system. When throttle input exceeds available grip, the system limits engine torque output to keep the rear wheel in line.
Drag-Torque Slip Control prevents rear wheel lock under abrupt downshifting or throttle release. The Cornering variant of this system accounts for lateral acceleration and lean to prevent destabilization during gear transitions.
Vehicle Hold Control engages automatically when the rider releases the brake lever or pedal while stopped on an incline. It maintains brake pressure to prevent rollback until throttle is applied.
The Tire Pressure Monitoring System alerts the rider when either tire’s pressure drops below or exceeds recommended values. Maintaining tire pressure contributes to consistent handling and braking effectiveness.
Trim and Visual Configuration
The 2025 Harley-Davidson® Street Glide® Ultra is offered in Chrome and Black trim variations. Each trim is paired with a range of color options. Shared colors include Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire with Vivid Black. The Black trim includes additional colorways such as Iron Horse Metallic and Mystic Shift. The tank medallion and center console accents are matched to the selected trim, providing consistency in appearance across body panels.
Model Role and Intended Use
This motorcycle is designed for extended touring with a passenger. Its engine is calibrated for high-load applications, and its suspension system is set to support consistent travel across varying terrain. The cockpit layout prioritizes information visibility, control reach, and comfort over extended durations.
Air management systems reduce rider fatigue and increase endurance. Luggage options provide the capacity required for multi-day travel. Integrated safety systems reduce the cognitive load on the rider during complex traffic or weather conditions.
