2025 Harley-Davidson® Street Glide® Ultra near Evans, GA
The 2025 Harley-Davidson® Street Glide® Ultra is designed specifically for two-up touring, combining substantial engine output with refined touring features and advanced rider assistance technologies. This motorcycle provides a technical composition focused on performance, rider comfort, and safety innovations to meet the demands of extended road travel.
Engine Specifications and Performance Capabilities
The 2025 Harley-Davidson® Street Glide® Ultra is equipped with the Milwaukee-Eight® 117 engine, delivering a rated output of 105 horsepower and a torque figure of 130 foot-pounds. The engine is also designed to balance power delivery with fuel efficiency, achieving a fuel economy of approximately 44 miles per gallon. The seat height, measured at 26.9 inches when carrying a rider and passenger, supports ergonomic positioning for control and stability on various road conditions.
Aerodynamic and Comfort-Driven Design
The motorcycle incorporates a redesigned Batwing fairing that has undergone computational fluid dynamics analysis and wind tunnel testing to improve airflow management. The fairing features a clear windshield that extends four inches higher than previous Harley-Davidson® Street Glide® models, which reduces helmet buffeting by up to 60 percent.
The seat is designed to accommodate two riders with ergonomic shaping that slightly rotates the rider’s hips forward to alleviate spinal pressure during extended periods of riding. Passenger comfort is addressed through a plush seat section, complete with a robust backrest and armrests integrated into the King Tour-Pak® luggage carrier. The luggage carrier, along with the hard-shell saddlebags and fairing cubbies, provides a combined storage capacity of 4.9 cubic feet, effectively doubling storage volume compared to the standard Harley-Davidson® Street Glide®. Additionally, saddlebag guards that match the bike’s trim protect bodywork in case of a tip-over.
Suspension and Ride Control
The 2025 Harley-Davidson® Street Glide® Ultra features SHOWA® dual outboard emulsion rear shocks with three inches of travel. The hydraulic preload on the rear shocks can be adjusted remotely by hand, allowing the rider to modify suspension stiffness according to load and road conditions without requiring tools. Aerodynamic efficiency is further enhanced by new fairing lowers fitted with adjustable air vents and larger fork-mounted air deflectors, both designed to redirect airflow and improve rider comfort by reducing wind pressure on the torso. The fairing skirt is optimized to complement the fairing lowers and contributes to wind management as well as visual cohesion of the motorcycle’s front-end design.
Infotainment and Display Technology
The model integrates a 12.3-inch color touchscreen display with the Skyline™ operating system. This TFT screen provides access to infotainment functions such as audio, navigation, and ride mode selection. Navigation functionality includes hands-free voice recognition, allowing riders to use simple voice commands to operate navigation features without manual input, which supports safer riding conditions. The system supports Apple CarPlay® for smartphone integration, facilitating seamless access to phone calls, messages, and media through the display. The audio system delivers up to 200 watts of power, ensuring clear sound quality even at highway speeds.
Advanced Rider Safety Systems
Safety is enhanced by a comprehensive suite of Rider Safety Enhancements designed to assist in various riding conditions. The Cornering Anti-lock Brake System (C-ABS) adjusts brake pressure based on the motorcycle’s lean angle, maintaining stability when braking through curves. Electronic Linked Braking (ELB) distributes braking force between front and rear wheels to improve stopping performance and rider control. The Traction Control System (TCS) prevents rear wheel spin during acceleration on low-traction surfaces, increasing rider confidence.
The Drag-Torque Slip Control System (DSCS) reduces rear wheel lockup during engine braking caused by abrupt downshifts or sudden throttle release, particularly useful on slippery or wet road surfaces. Vehicle Hold Control (VHC) maintains brake pressure after the rider releases the brake lever or pedal at a stop, preventing roll-back on inclines. The Tire Pressure Monitoring System (TPMS) continuously monitors tire pressure and provides alerts via the information display when pressure deviates from optimal levels.
Integrated Ride Control Systems and Handling Enhancements
The motorcycle’s aerodynamic features work in conjunction with suspension and braking systems to improve overall ride stability. Larger fork-mounted air deflectors and adjustable fairing lowers give riders control over airflow, allowing for either increased ventilation or enhanced wind protection based on preference and environmental conditions. The suspension system’s adjustable preload allows rapid adaptation to passenger weight and cargo, maintaining ride quality across different load scenarios.
Cornering-enhanced versions of ABS, ELB, TCS, and DSCS integrate lean angle and lateral acceleration data to refine control inputs during turns.
