The 2025 Harley-Davidson® Street Glide® Ultra is engineered as a purpose-built touring motorcycle with performance, durability, and comfort designed for extensive miles on the road. Its V-twin powertrain, modern rider technology, optimized aerodynamics, and extensive storage capacity combine into a machine focused entirely on capability. The 2025 Harley-Davidson® Street Glide® Ultra extends the legacy of Harley-Davidson® touring models by refining the technical systems that define two-up riding and long-distance travel.
Engine Output and Fuel Efficiency
The 2025 Harley-Davidson® Street Glide® Ultra features a Milwaukee-Eight® 117 V-twin engine. This power unit delivers 105 horsepower and 130 foot-pounds of torque, providing smooth performance across highways and varied terrain. The design emphasizes efficiency as well as strength, offering a fuel economy rating of 44 miles per gallon. This balance of output and economy makes the motorcycle capable of covering long stretches between refueling while maintaining steady acceleration and confident passing power.
Aerodynamic Fairing and Wind Protection
The motorcycle incorporates the Batwing fairing, which has been refined through computational fluid dynamics analysis, wind tunnel testing, and extended on-road evaluation. The new fairing reduces helmet buffeting by up to sixty percent compared to previous designs. It is matched with a taller windshield that measures four inches higher than the windshield on standard Street Glide® models. The combination improves comfort, reduces rider fatigue, and provides stability at sustained touring speeds.
The fairing skirt has been redesigned to integrate visually while improving aerodynamic flow. Adjustable fork-mounted air deflectors further contribute to air management. These deflectors can redirect wind away from the rider or allow additional airflow when needed. The new lower fairing, fitted with adjustable air vents, complements this system by enhancing both rider comfort and long-distance stability.
Touring Seat and Passenger Comfort
The 2025 Harley-Davidson® Street Glide® Ultra is designed for extended two-up riding. The newly developed comfort seat is engineered with an ergonomic angle that rotates the rider’s hips forward. This adjustment reduces spinal pressure and provides a seating position optimized for long hours of operation. Heated grips contribute additional comfort for the rider.
For passengers, the King Tour-Pak® luggage carrier incorporates a robust back pad and armrests. Together with the seating design, these elements provide both occupants with sustained support during long touring routes.
Storage and Utility
The motorcycle is equipped with storage solutions built for extended travel. The King Tour-Pak® luggage carrier, saddlebags, and fairing cubbies provide a combined 4.9 cubic feet of storage capacity. This is more than twice the space available on the standard Street Glide®. The hard-shell design ensures durability, while the configuration allows riders to carry equipment and personal items in a secure and accessible manner.
Additional features include saddlebag guards that match the motorcycle’s trim finish. These guards protect the bodywork in case of a tip-over, offering both function and integration with the motorcycle’s overall design.
Suspension and Handling
The suspension system is designed to balance comfort with responsive handling. Rear shocks with SHOWA® dual outboard emulsion technology provide three inches of travel. These shocks deliver consistent ride quality across varying road conditions. Riders can adjust preload hydraulically with a hand-operated control, simplifying changes when carrying passengers or luggage.
The suspension components are combined with the aerodynamic fairing system to maintain stability at both highway speed and during maneuvering in tighter environments. The fairing lowers and fork-mounted deflectors also contribute to reduced turbulence, ensuring handling remains predictable and controlled.
Advanced Display and Infotainment
The 2025 Harley-Davidson® Street Glide® Ultra is equipped with a 12.3-inch TFT display featuring the Skyline™ operating system. The touchscreen provides access to infotainment, embedded navigation, and customizable ride modes. The screen maintains clarity for essential information while offering modern connectivity options.
The system supports voice recognition, allowing riders to operate navigation through conversational commands. For example, the rider can request a fuel station without manual input. The infotainment system is designed to minimize distraction while maintaining functionality, making it suitable for long-distance travel and changing road conditions.
Rider Safety Enhancements
The 2025 Harley-Davidson® Street Glide® Ultra includes the Harley-Davidson® Rider Safety Enhancements package. This suite of technologies is designed to manage traction, braking, and stability in both straight-line and cornering conditions.
The Anti-lock Brake System (ABS) prevents wheel lock during braking, assisting the rider in maintaining control. Electronic Linked Braking applies balanced force to both wheels, enhancing stopping performance. The Traction Control System reduces rear wheel spin during acceleration. Drag-Torque Slip Control moderates excessive slip or potential lockup during abrupt downshifts or throttle reduction. Vehicle Hold Control keeps the motorcycle steady on inclines by holding brake pressure until the rider accelerates. The Tire Pressure Monitoring System alerts the rider to improper pressure levels, contributing to both safety and tire longevity.
Cornering-Optimized Systems
In addition to straight-line safety functions, the 2025 Harley-Davidson® Street Glide® Ultra features cornering-optimized technologies. Cornering Enhanced ABS adjusts braking based on lean angle to reduce wheel slip in turns. Cornering Enhanced Linked Braking modifies brake distribution when leaning, improving control of the motorcycle’s intended path. Cornering Enhanced Traction Control prevents wheel spin while accelerating through a corner. Cornering Drag-Torque Slip Control adjusts engine braking during lean, keeping the rear wheel from slipping or locking in downshifts.
These systems work together to provide stability, particularly during wet or unpredictable conditions. Each element is designed to operate seamlessly, maintaining control without requiring additional rider input.
Trim Options and Finishes
The 2025 Harley-Davidson® Street Glide® Ultra is available in two trims. The chrome trim includes colors such as Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire. The black trim includes those same colors, along with Iron Horse Metallic with Vivid Black and Mystic Shift. Both trims include a new fuel tank medallion available in chrome or black, designed to align with the overall finish of the motorcycle.
Touring Systems in Combination
When combined, the powertrain, suspension, aerodynamic design, infotainment, and safety technologies form a complete touring system. Each feature addresses a specific element of long-distance riding. The motorcycle is engineered to maintain stability, provide sufficient power output, manage aerodynamic resistance, and ensure both rider and passenger comfort over long stretches of road.
