The 2025 Harley-Davidson® Street Glide® Ultra is developed specifically for two-up touring. It combines a robust V-twin engine, aerodynamic design based on extensive testing, and advanced rider assistance technologies. Every element of this motorcycle supports long-distance riding with a focus on performance, comfort, and control.
Engine Power and Fuel Efficiency
The motorcycle features the Milwaukee-Eight® 117 V-twin engine, delivering 105 horsepower and 130 foot-pounds of torque. This power output provides consistent acceleration and reliable performance even when the bike is fully loaded with two riders and luggage. Fuel consumption is rated at approximately 44 miles per gallon, balancing the engine’s size and power with efficient touring capability. The 26.9-inch seat height when laden allows for stable rider positioning and control, especially during stops or low-speed maneuvers.
Aerodynamic Refinements and Rider Comfort
Aerodynamic improvements result from computational fluid dynamics and wind tunnel testing. The signature Batwing fairing is reshaped to optimize airflow for both rider and passenger. The windshield is four inches taller than the standard Street Glide® model. This reduces helmet buffeting by up to 60 percent, which contributes to rider comfort over long distances.
The two-up comfort seat has been redesigned to rotate the rider’s hips forward, reducing pressure on the spine during extended rides. Heated grips are included to maintain hand warmth and ensure better control in cooler temperatures.
Suspension and Handling Features
SHOWA® dual outboard emulsion rear shocks offer three inches of travel. These shocks provide a balance of comfort and responsiveness on varying road surfaces. Hydraulic remote preload adjustments allow riders to tune the suspension stiffness quickly and without tools to suit load or road conditions.
The motorcycle also includes fairing lowers with adjustable air vents and fork-mounted air deflectors. These allow airflow to be directed away from the rider or toward the torso based on preference. The fairing skirt is optimized to work with these elements, improving wind management and maintaining aerodynamic efficiency.
Infotainment and User Interface
A 12.3-inch touchscreen TFT display equipped with the Skyline™ operating system serves as the control center. The display offers clear access to navigation, audio, and ride mode selection. Integration with Apple CarPlay® allows riders to connect smartphones for calls, music, and other functions. The hands-free voice recognition system accepts conversational commands, such as requesting directions, which helps reduce distractions while riding.
The audio system delivers 50 watts per channel, providing clear audio without compromising situational awareness. Four ride modes can be selected through the display, allowing riders to tailor performance to different conditions.
Advanced Rider Safety Systems
The 2025 Harley-Davidson® Street Glide® Ultra includes a comprehensive set of rider safety technologies. The Cornering Enhanced Anti-lock Brake System (C-ABS) adjusts brake pressure based on the lean angle to prevent wheel lockup during turns. Electronic Linked Braking (ELB) applies braking force to both wheels when the front brake lever is engaged, enhancing braking stability.
Traction Control System (TCS) monitors and limits rear wheel spin during acceleration to maintain stability on varying surfaces. Drag-Torque Slip Control System (DSCS) reduces rear wheel slip or lockup during quick downshifts or throttle release, especially on slippery roads, adjusting for lean angle during cornering.
Vehicle Hold Control (VHC) maintains brake pressure after the rider releases the brake lever or pedal on inclines, preventing rollback during hill starts. This is a temporary hold and does not replace the parking brake. The Tire Pressure Monitoring System (TPMS) continuously checks tire pressure and alerts the rider if air pressure falls outside recommended levels, which supports safe handling and tire longevity.
Design Elements and Finishes
The 2025 Harley-Davidson® Street Glide® Ultra offers two trim options: Chrome and Black. Color selections include Billiard Gray, Vivid Black, Blue Burst, Whiskey Fire with Vivid Black, Iron Horse Metallic with Vivid Black, and Mystic Shift. These finishes are applied to the fuel tank medallion, saddlebag guards, and other trim components to maintain visual coherence.
The King Tour-Pak® luggage carrier includes a passenger back pad with armrests to increase passenger support during extended rides. The protective saddlebag guards against damage from minor falls without affecting the bike’s styling. Combined with its storage capacity, these design elements enhance the motorcycle’s suitability for long-distance touring.
