Key Features of the 2025 Harley-Davidson® Street Glide® Ultra

Milwaukee-Eight® 117 V-Twin Engine

At the heart of the 2025 Harley-Davidson® Street Glide® Ultra lies the Milwaukee-Eight® 117 V-Twin engine. This latest generation powerplant is renowned for its robust torque, quick throttle response, and refined performance. The liquid-cooled cylinder heads and a centrally located radiator direct air to the intake for accelerated cooling, especially crucial during long, demanding rides. Riders will enjoy the added horsepower and responsiveness over previous Twin-Cooled 114 engines, ensuring that every twist of the throttle delivers immediate and satisfying power, whether you’re cruising highways or climbing mountain passes.

Ergonomic Touring Comfort

Designed for distance, the Street Glide® Ultra features an all-day two-up comfort seat. This new seat rotates the rider's hips forward to relieve spinal pressure, making long journeys noticeably more comfortable. Heated grips are standard, allowing for greater comfort during cold weather, and the plush passenger accommodations, complete with back pad and armrests, guarantee your co-rider feels every mile melt away. Thoughtful details, such as optimized seat height and advanced suspension, further contribute to supreme ride quality, ensuring you remain fresh and comfortable no matter how far your adventure takes you.

Advanced Storage Solutions

Touring often means packing for unpredictability, which is why Harley-Davidson® has equipped the Street Glide® Ultra with industry-leading storage. The standard King Tour-Pak® luggage carrier features a robust back pad and armrests for passenger comfort while offering deep, secure space for travel essentials. Fairing cubbies and hard-shell saddlebags deliver a combined 4.9 cubic feet of storage—more than twice that of a standard Street Glide®. Whether you're carrying luggage, tools, or riding gear, you never have to worry about leaving necessities behind.

Batwing Fairing and Wind Protection

The iconic Batwing fairing is meticulously engineered for both aesthetics and function. Utilizing computational fluid dynamics and wind-tunnel testing, the design delivers reduced turbulence and improved rider comfort. The taller windshield, standard on the Ultra, cuts helmet buffeting by up to 60% compared to other models. Adjustable fairing lowers and larger fork-mounted air deflectors give riders full control to customize airflow and improve aerodynamic comfort, no matter the road or weather conditions.

Modern Technology and Rider Safety Enhancements

The 2025 model introduces Harley-Davidson®’s most advanced 12.3-inch TFT display. This vibrant color touchscreen, powered by Skyline™ OS, centralizes navigation, infotainment, and four ride mode selections in an intuitive interface. Hands-free voice recognition and Vehicle Hold Control contribute to ease and rider safety, especially on inclines or stops. The well-integrated technology supports rider confidence and greatly enhances convenience for today’s tech-oriented enthusiasts, ensuring every trip is as worry-free as it is exhilarating.
