The 2025 Harley-Davidson® Street Glide® Ultra is designed specifically for extended two-up touring with a strong focus on technical performance and rider functionality. It combines a powerful engine, aerodynamic advancements, and an array of modern features developed through extensive testing to deliver a consistent and controlled riding experience on long journeys. The model reflects deliberate engineering choices intended to enhance comfort, improve handling, and integrate technology without compromising the classic touring motorcycle form.
Suspension Tuned for Stability and Long-Distance Comfort
The Milwaukee-Eight® 117 V-Twin drives the 2025 Street Glide® Ultra with 105 horsepower and 130 ft-lb of torque, giving it the strength to handle touring loads without compromising acceleration or cruising speed. This engine maintains steady performance under weight. With an estimated fuel economy of 44 miles per gallon, the bike supports longer rides with fewer stops. The balance of torque and efficiency makes it a practical choice for extended touring. Power delivery remains stable and responsive across highway and urban conditions.
Engine management and performance are supported by a chassis designed to maintain stability and control. The rear suspension features SHOWA® dual outboard emulsion shocks with three inches of travel. These shocks employ adjustable remote hydraulic preload, enabling fine-tuning of ride firmness to suit varying loads and road conditions. The suspension setup provides a balance between comfort and responsiveness required for long-distance touring across diverse terrains.
Ergonomic Seating and Passenger-Centric Amenities
The model’s aerodynamic design has been refined through computational fluid dynamics and wind tunnel testing. This process led to the development of a Batwing fairing optimized to reduce wind resistance and rider fatigue. A clear windshield, standing four inches taller than those on standard Street Glide® models, reduces helmet buffeting by approximately 60 percent. These enhancements contribute to lower rider fatigue and improved comfort over long rides.
The two-up seat is ergonomically designed to rotate the rider’s hips forward, reducing pressure on the spine during extended riding periods. Heated hand grips provide temperature regulation in cooler conditions. Passenger comfort is addressed with a King Tour-Pak® luggage carrier featuring a substantial back pad with integrated armrests. Storage capacity is expanded through hard-shell saddlebags and fairing cubbies, delivering a combined 4.9 cubic feet of storage.
Saddlebag guards matched to the bike’s trim protect body panels in the event of a tip-over. A new fuel tank medallion in chrome or black, along with distinctive console inserts, visually differentiates this model without compromising functional design.
Audio, Navigation, and Ride Mode Personalization
A 12.3-inch full-color touchscreen display with Skyline™ OS functions as the central control for infotainment, navigation, and ride mode selection. The interface supports hands-free voice commands for navigation and other functions, improving rider focus and safety. Apple CarPlay® integration allows seamless smartphone connectivity for media and communication.
The audio system delivers 50 watts per channel, providing clear audio output suitable for highway speeds. Navigation can be accessed via simple voice commands such as “Find me a gas station,” minimizing distraction. The system’s design allows for easy switching between four available ride modes to tailor performance to varying road conditions and rider preferences.
Traction and Slip Control for All Conditions
The 2025 Harley-Davidson® Street Glide® Ultra includes multiple electronic safety features designed to assist in maintaining control during various riding scenarios. The Anti-lock Brake System (ABS) prevents wheel lockup during abrupt braking, which helps maintain steering control. Electronic Linked Braking (ELB) applies braking pressure to both wheels when the front brake lever or rear brake pedal is used, ensuring balanced stopping force.
Traction Control System (TCS) prevents excessive rear wheel spin under acceleration, which enhances stability on surfaces with low traction. The Drag-Torque Slip Control System (DSCS) reduces rear wheel slip caused by abrupt downshifts or sudden throttle release, particularly on wet or slippery roads.
The model also integrates cornering-specific safety enhancements that adjust braking and traction control based on lean angle. Cornering Enhanced ABS (C-ABS) and Cornering Enhanced ELB (C-ELB) modulate brake pressure during turns to support rider stability and path control. Cornering Enhanced TCS (C-TCS) prevents rear wheel spin during acceleration through corners, and Cornering Drag-Torque Slip Control (C-DSCS) manages rear wheel slip when decelerating in turns.
Vehicle Hold Control (VHC) maintains brake pressure after stopping, preventing unintended rolling on inclines. This system is activated by squeezing and releasing the front brake lever or rear brake pedal at a stop. The Tire Pressure Monitoring System (TPMS) continuously monitors air pressure and provides alerts for abnormal tire conditions, supporting optimal tire performance and safety.
Integrated Fairing Skirt for Flow and Style
Fairing lowers equipped with adjustable air vents, combined with larger fork-mounted air deflectors, allow riders to customize airflow around the torso and upper body. These adjustments contribute to thermal regulation and reduce wind turbulence, improving overall comfort in varying weather conditions.
A fairing skirt has been developed to work in conjunction with the lowers, enhancing aerodynamic flow and visual coherence while contributing to wind management. These features reflect detailed attention to environmental adaptation during long-distance travel.
