The 2025 Harley-Davidson® Street Glide® Ultra is designed for riders seeking advanced touring capability with precise engineering, aerodynamic refinements, and integrated technology. Built as the most capable two-up touring motorcycle in the Harley-Davidson® Street Glide® family, it delivers reliable performance, consistent comfort, and safety systems engineered to adapt to changing road conditions.
Engine Output and Mechanical Efficiency
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 V-Twin engine. This powertrain produces 105 horsepower and 130 ft-lb of torque, providing smooth acceleration across a broad range of speeds. Its design balances performance and efficiency, allowing for strong passing power and dependable highway cruising while maintaining a fuel economy of 44 miles per gallon.
Touring Seat and Passenger Accommodation
Long-distance riding requires a seating design that reduces pressure and increases support. The 2025 Harley-Davidson® Street Glide® Ultra introduces a touring seat built to rotate the rider’s hips forward, easing strain on the spine during extended rides. This seat design combines ergonomic support with comfort for the passenger, ensuring balanced weight distribution over many hours of use.
Passenger features include a supportive back pad with armrests integrated into the King Tour-Pak® luggage carrier. The combination of these elements ensures stability and comfort for two-up riding, addressing the demands of riders who frequently travel with a passenger on extended routes.
Aerodynamics and Wind Management
Aerodynamic efficiency has been a priority in the development of the 2025 Harley-Davidson® Street Glide® Ultra. The iconic Batwing fairing was refined using computational fluid dynamics and wind-tunnel testing. A new clear windshield that is four inches taller than standard Harley-Davidson® Street Glide® models reduces helmet buffeting by up to 60 percent.
New fairing lowers include adjustable air vents, which work in coordination with fork-mounted air deflectors. These components provide flexibility for airflow control, allowing riders to direct wind toward or away from the torso depending on conditions. A redesigned fairing skirt complements the system, further refining airflow and contributing to a smoother aerodynamic profile.
Suspension and Handling Characteristics
Handling performance is supported by SHOWA® dual outboard emulsion technology shocks with three inches of rear travel. These shocks deliver consistent performance across varied road surfaces. Riders can make preload adjustments by hand using the remote hydraulic adjustment feature, allowing for quick setup based on load and passenger weight.
Storage and Functional Design
The 2025 Harley-Davidson® Street Glide® Ultra offers a combined 4.9 cubic feet of storage capacity. The King Tour-Pak® luggage carrier, saddlebags, and integrated fairing cubbies provide ample space for extended touring gear. The passenger back pad incorporated into the luggage carrier improves comfort without sacrificing storage capability.
Additional design elements include saddlebag guards finished to match the motorcycle’s trim, protecting bodywork in the event of a tip-over. A new fuel tank medallion is available in chrome or black depending on trim, with console inserts featuring the 2025 Harley-Davidson® Street Glide® Ultra name to distinguish the model.
Infotainment and Control Systems
The motorcycle incorporates a 12.3-inch TFT display with Skyline™ OS, the most advanced system offered on a Harley-Davidson® touring model. The high-resolution display provides infotainment, navigation, and ride mode selection in a single interface. Riders can switch seamlessly between four ride modes, each programmed to adjust performance characteristics for varying conditions.
Navigation is supported by a hands-free voice recognition system that accepts conversational commands, simplifying tasks such as searching for a gas station or setting a destination. A 200-watt audio system delivers clear sound, while Apple CarPlay® compatibility keeps riders connected to their devices with minimal distraction.
Rider Safety Enhancements
The 2025 Harley-Davidson® Street Glide® Ultra includes Rider Safety Enhancements, which apply traction, braking, and stability technologies to support rider control in varied conditions.
The Anti-lock Brake System is designed to prevent wheel lock during sudden braking in a straight line, maintaining stability in urgent stops. Electronic Linked Braking automatically distributes braking effort between the front and rear wheels, increasing performance and confidence across a range of speeds. Traction Control prevents the rear wheel from spinning during acceleration, while Drag-Torque Slip Control minimizes rear-wheel slip during abrupt downshifts or throttle reductions.
Vehicle Hold Control provides security when starting on inclines, keeping the motorcycle stationary until the rider accelerates. The Tire Pressure Monitoring System communicates low or high tire pressure directly to the display, supporting both performance and tire longevity.
Cornering Rider Safety Enhancements
For improved handling during turns, the 2025 Harley-Davidson® Street Glide® Ultra features Cornering Rider Safety Enhancements. Cornering Enhanced ABS adjusts brake pressure when leaning into a turn, preventing wheel slip while preserving the rider’s intended line. Cornering Enhanced Linked Braking distributes brake force between the wheels based on lean angle.
Cornering Enhanced Traction Control prevents excess wheel spin during cornering acceleration, while Cornering Drag-Torque Slip Control adjusts deceleration response to prevent skidding on wet or uneven surfaces.
Trim and Paint Options
The 2025 Harley-Davidson® Street Glide® Ultra is available in Chrome or Black trim packages. Both trims offer multiple paint options, including Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire/Vivid Black. The Black trim package adds Iron Horse Metallic/Vivid Black and Mystic Shift finishes, allowing riders to configure the motorcycle to match their preferred aesthetic while maintaining consistent technical specifications across all versions.
