The 2025 Harley-Davidson® Street Glide® Ultra is a two-up touring motorcycle designed with advanced engineering and proven long-distance performance. Built with the Milwaukee-Eight® 117 engine, new aerodynamic refinements, extensive storage solutions, and a full suite of safety technologies, this model is equipped for long-haul travel. Each feature has been developed with precision testing and is supported by the decades of touring expertise of Harley-Davidson®.
Engine Specifications and Performance Dynamics
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 V-twin engine, which produces 105 horsepower and 130 ft-lb of torque. This engine provides consistent power delivery for highway speeds and mountain roads alike.
Fuel efficiency is rated at 44 miles per gallon. This allows extended distance between refueling stops. The torque curve supports passing and climbing without loss of performance, reinforcing the model’s role as a capable touring platform.
Rear suspension performance is managed by SHOWA® dual outboard emulsion technology shocks, offering three inches of travel. Remote hydraulic preload adjustments are made by hand, allowing the rider to adapt suspension stiffness to weight and load conditions without requiring tools.
Aerodynamic Refinements and Rider Comfort
The Batwing fairing of the 2025 Harley-Davidson® Street Glide® Ultra has been shaped through computational fluid dynamics, wind tunnel testing, and extended on-road development. The fairing integrates a windshield that is four inches taller than standard Harley-Davidson® Street Glide® models. This design reduces helmet buffeting by up to 60 percent, providing improved rider comfort and reduced fatigue on extended rides.
The fairing system includes new lowers with adjustable vents and larger fork-mounted deflectors. These components improve aerodynamic flow and allow adjustments to redirect or increase airflow based on rider preference and climate. The fairing skirt integrates with these systems to create a unified structure that enhances both aerodynamics and visual design.
Ergonomics are addressed with a two-up comfort seat. The design rotates the rider’s hips forward to relieve spinal pressure, supporting extended time in the saddle. The passenger area is equipped with a King Tour-Pak® luggage carrier featuring a robust back pad and integrated armrests. Heated grips come standard, ensuring consistent hand comfort during colder temperatures.
Touring Storage and Utility Features
Touring capability relies heavily on cargo capacity, and the 2025 Harley-Davidson® Street Glide® Ultra provides a total of 4.9 cubic feet of storage. This includes the King Tour-Pak® hard-shell luggage carrier, large saddlebags, and integrated fairing cubbies. The system provides more than twice the storage of the standard Harley-Davidson® Street Glide®.
The storage design integrates a passenger backrest into the Tour-Pak®, which enhances passenger comfort without compromising utility. Saddlebag guards are included, protecting the motorcycle’s finish in the event of a tip-over. The fuel tank features a newly designed medallion that aligns with the trim option chosen, available in either chrome or black finishes.
Suspension, Braking, and Handling
The suspension system combines rear SHOWA® shocks with adjustable preload and front-end deflectors that enhance both aerodynamics and rider control. Handling stability is further reinforced by the fairing lowers and skirt, which manage airflow and reduce turbulence at higher speeds.
Braking performance is supported by an advanced set of electronic systems. Electronic Linked Braking distributes braking effort between the front and rear wheels to improve stopping power in a variety of conditions. The Anti-lock Brake System prevents wheel lock-up during urgent stops and supports control during straight-line braking.
For added stability on inclines, Vehicle Hold Control engages with a simple squeeze and release of the brake lever. This feature keeps the motorcycle steady on slopes until the rider applies throttle, preventing rollback and ensuring controlled starts.
Advanced Infotainment and Rider Interface
The 12.3-inch Skyline™ OS color touchscreen TFT display is the centerpiece of the motorcycle’s infotainment system. The display is crystal-clear and easy to navigate while riding. It provides access to four selectable ride modes, embedded navigation, and entertainment controls.
The integrated voice recognition system enhances navigation functions. Riders can issue simple voice commands, such as requests for nearby fuel stations, without removing their hands from the handlebars. Connectivity includes Apple CarPlay®, ensuring seamless access to communication and media applications. The infotainment system is paired with a 200-watt audio system, providing clear sound output that remains consistent at highway speeds.
Safety Technologies and Rider Assistance
The 2025 Harley-Davidson® Street Glide® Ultra incorporates a full suite of Rider Safety Enhancements. These systems support control during acceleration, braking, and deceleration, particularly in less predictable riding environments.
The Traction Control System manages rear-wheel spin during straight-line acceleration, while the Drag-Torque Slip Control System helps prevent lock-up during abrupt downshifts or throttle reductions. Tire Pressure Monitoring alerts the rider when tire inflation falls outside of optimal ranges, ensuring tire longevity and performance.
Cornering enhancements include C-ABS, C-ELB, C-TCS, and C-DSCS. These systems actively account for lean angle while braking, accelerating, or downshifting. For example, Cornering Enhanced ABS adjusts brake pressure to prevent wheel slip in lean conditions, and Cornering Enhanced Traction Control balances rear-wheel spin both in straight-line and cornering scenarios. Cornering Enhanced Electronic Linked Braking modifies brake proportioning during cornering to maintain the intended line.
Trim Levels and Available Colors
The 2025 Harley-Davidson® Street Glide® Ultra is offered in both Chrome and Black trim levels. Color options include Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire/Vivid Black. Black trim expands the range further with Iron Horse Metallic/Vivid Black and Mystic Shift. The tank medallion design is finished to align with the chosen trim, while saddlebag guards and other exterior elements match accordingly.
