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 is the Milwaukee-Eight® 117 V-Twin Engine—a force of modern V-Twin engineering. Delivering more torque and horsepower than the previous 114 engine, the 117 features liquid-cooled cylinder heads and a centrally located radiator that directs airflow efficiently to optimize cooling and sustained high performance. This robust powerplant ensures brisk acceleration, smooth cruising, and impressive low-end torque, making it equally adept at conquering twisty roads or sustained highway speeds. With this engine, every ride is thrilling yet refined, reinforcing the legacy of Harley-Davidson® dominance on the open road.

12.3-Inch TFT Display with Skyline™ OS

The new 12.3-Inch TFT Display serves as both the command center and digital dashboard for your journey. Its crystal-clear, easy-to-read interface incorporates the intuitive Skyline™ OS, providing seamless access to infotainment, navigation, and the ability to switch between four unique ride modes—tailoring your ride for every condition. The display also features an advanced hands-free Voice Recognition System, making navigation and system control both safer and more convenient. This high-tech integration places essential information within effortless reach, ensuring that you stay in full command without distraction from your surroundings.

Premium Touring Comfort and Ergonomics

Touring comfort is paramount, and the 2025 Street Glide® Ultra excels with thoughtful rider and passenger amenities. The newly designed two-up comfort seat ergonomically rotates the rider’s hips forward, relieving spinal pressure and promoting long-haul comfort. Heated grips, a plush passenger backrest with armrests, and ergonomic controls cater to all-day riding needs, allowing for fatigue-free miles whether you’re traveling solo or sharing the adventure. This focus on rider and passenger well-being is fundamental to every aspect of the Street Glide® Ultra’s design.

Expanded Storage and King Tour-Pak® Luggage Carrier

The Street Glide® Ultra transforms touring convenience with the standard King Tour-Pak® luggage carrier, hard-shell side saddlebags, and fairing cubbies—all combining for a remarkable 4.9 cubic feet of storage. The King Tour-Pak® provides a robust passenger back pad and armrests, ensuring comfort on extended journeys while organizing travel essentials. This increased storage is more than double that of the base Street Glide®, ensuring that packing for weeklong getaways or quick weekend excursions is effortless and secure. Customizable inserts and storage options further enhance the motorcycle’s capacity and usability.

Optimized Wind and Weather Protection

The Batwing fairing, refined through computational fluid dynamics (CFD), wind-tunnel testing, and on-road development, offers iconic style with best-in-class wind protection. The windshield rises four inches taller than standard Street Glide® models, significantly reducing helmet buffeting by up to 60 percent. Added features like new fairing lowers with adjustable vents, expanded fork-mounted air deflectors, and a coordinating fairing skirt work together to minimize wind fatigue and improve overall ride comfort, no matter the conditions. These advancements exemplify Harley-Davidson®’s dedication to practical, rider-focused innovation.
