The 2025 Harley-Davidson® Street Glide® Ultra is engineered as a two-up touring motorcycle that integrates performance, comfort, and advanced technology. It represents the most capable model in the Harley-Davidson® Street Glide® lineup, with refinements focused on long-distance travel. This model emphasizes functional design, improved aerodynamics, advanced infotainment, and an extensive range of safety enhancements. Each element of the motorcycle is designed with precision to provide consistent performance and rider confidence across varied road conditions.
Engine Specifications and Power Output
The 2025 Harley-Davidson® Street Glide® Ultra is powered by the Milwaukee-Eight® 117 V-twin engine. This engine produces 105 horsepower and 130 foot-pounds of torque, allowing the motorcycle to sustain steady acceleration and strong passing capability. The design of the Milwaukee-Eight® 117 is focused on delivering consistent torque across the usable rev range, ensuring smooth performance at both low and high speeds.
The engine’s cooling system and fuel injection have been calibrated for efficiency as well as endurance, supporting long-distance travel without sacrificing performance. With an average fuel economy of 44 miles per gallon, the model is engineered for extended journeys between refueling stops.
Long-Distance Ergonomics and Rider Comfort
Touring demands an ergonomic structure that minimizes fatigue. The 2025 Harley-Davidson® Street Glide® Ultra incorporates a two-up comfort seat that ergonomically rotates the rider’s hips forward. This adjustment relieves spine pressure and ensures support for extended riding sessions. The seat design accommodates both rider and passenger with padding tailored for long-distance comfort.
Heated hand grips come standard, adding functionality in colder climates. The ergonomic placement of controls ensures that adjustments can be made without unnecessary effort or distraction.
Aerodynamic Refinements and Wind Management
The 2025 Harley-Davidson® Street Glide® Ultra introduces a refined aerodynamic system built through computational fluid dynamics and wind-tunnel testing. The Batwing fairing, a defining feature of the Harley-Davidson® Street Glide® line, is optimized to reduce buffeting. Combined with a windshield that is four inches taller than the one used on standard Harley-Davidson® Street Glide® models, helmet buffeting is reduced by up to 60 percent.
The motorcycle includes new fairing lowers equipped with adjustable air vents. These lowers work alongside enlarged fork-mounted air deflectors to manage airflow around the rider. Both systems allow riders to control airflow direction, either deflecting wind away or channeling it toward the torso for cooling. A redesigned fairing skirt complements these features by improving airflow balance and maintaining consistent handling.
Touring Storage and Functional Details
Storage is a critical component of a touring motorcycle, and the 2025 Harley-Davidson® Street Glide® Ultra provides 4.9 cubic feet of combined capacity. This total is more than double that of the standard Harley-Davidson® Street Glide®. The King Tour-Pak® luggage carrier includes a back pad with armrests for passenger support and is paired with saddlebags and fairing cubbies. Each storage compartment is engineered with hard-shell protection for durability and security.
Functional refinements also extend to protective hardware. Saddlebag guards, finished to match the overall design, protect bodywork from damage in the event of a tip-over. A new fuel tank medallion, available in chrome or black depending on the selected trim, further distinguishes the model.
Suspension and Ride Dynamics
The ride quality of the 2025 Harley-Davidson® Street Glide® Ultra is defined by its SHOWA® dual outboard emulsion technology shocks. With three inches of travel, these shocks are designed to maintain consistent performance across varied road conditions. Remote hydraulic preload adjustments can be completed by hand, allowing for quick customization when switching between solo riding and two-up touring.
The suspension works in conjunction with the motorcycle’s aerodynamic refinements, delivering both comfort and stability.
Infotainment and Connectivity
The 2025 Harley-Davidson® Street Glide® Ultra is equipped with the most advanced infotainment system. A 12.3-inch color TFT display with Skyline™ OS provides a high-resolution interface for navigation, audio, and system controls. The touchscreen design allows riders to make adjustments quickly, while the layout ensures clear visibility in varied lighting conditions.
The system supports Apple CarPlay® integration and includes embedded navigation with voice recognition. Riders can issue simple verbal commands such as “Find me a gas station” to initiate navigation functions without manual input. The system is paired with a 200-watt audio setup designed to deliver clarity at both city and highway speeds.
Rider Safety Enhancements
Safety systems on the 2025 Harley-Davidson® Street Glide® Ultra represent one of the most comprehensive suites available on a Harley-Davidson® touring model. The motorcycle integrates the Rider Safety Enhancements package, which applies advanced technology to improve control during acceleration, braking, and cornering.
The standard Anti-lock Braking System prevents wheel lock during urgent straight-line braking, while the Electronic Linked Braking system distributes brake force between the front and rear wheels. Cornering-specific enhancements refine these systems further, with Cornering-ABS and Cornering-ELB adjusting brake performance based on lean angle.
The Traction Control System prevents rear wheel spin during acceleration, and the Cornering Traction Control System adjusts performance in leaned positions. Drag-Torque Slip Control reduces rear-wheel slip during rapid deceleration or downshifting, with Cornering DSCS modifying the system for cornering situations. Vehicle Hold Control prevents rollback on inclines by holding brake pressure until the rider applies throttle. Tire Pressure Monitoring alerts the rider to low or high tire pressure, helping maintain both safety and tire longevity.
Trim Packages and Color Options
The 2025 Harley-Davidson® Street Glide® Ultra is available in two trim levels, Chrome and Black. Each trim offers a set of finishes that align with rider preference for styling while maintaining consistent technical specifications. The Chrome trim includes color options such as Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire with Vivid Black. The Black trim expands these options with Iron Horse Metallic with Vivid Black and Mystic Shift.
Both trims maintain uniform mechanical features, ensuring that the choice of appearance does not affect the motorcycle’s performance. Riders are able to select a visual package that matches their individual preference without compromising technical capability.
