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

Milwaukee-Eight® 117 V-Twin Engine

At the heart of the Street Glide® Ultra is the Milwaukee-Eight® 117, a V-Twin built for effortless passing power and a confident highway cadence. Liquid-cooled cylinder heads help stabilize temperatures in traffic and on steep grades, while a centrally located radiator channels air directly into the intake for quicker cooling. The result is steady performance mile after mile, with the kind of roll-on response riders appreciate when merging, overtaking, or climbing through winding terrain. Paired with advanced aerodynamics and touring geometry, the 117’s torque delivery complements the chassis, making the bike feel planted and responsive even when fully loaded with gear and a passenger.

12.3-Inch TFT Display

The 12.3-Inch color TFT is Harley-Davidson® at its most intuitive. Running Skyline™ OS, the display streamlines access to navigation, infotainment, and the motorcycle’s four ride modes. The large, crystal-clear interface makes data legible at a glance in a variety of lighting conditions, while the Hands-free Voice Recognition System keeps navigation simple with conversational commands like “Find me a gas station.” Menus are designed to reduce distraction, so you can fine-tune audio, view turn-by-turn directions, or check key vehicle information without breaking your rhythm. The interface is the central hub for your ride, keeping technology helpful and unobtrusive.

SHOWA® Dual Outboard Emulsion Rear Shocks

Suspension makes or breaks long-distance comfort. With three inches of travel and SHOWA® dual outboard emulsion technology, the Street Glide® Ultra provides a compliant, consistent ride. Remote hydraulic preload is adjusted by hand—no tools—so you can dial in support for solo rides, two-up touring, or full luggage in seconds. That easy adjustability helps the chassis maintain proper geometry under load, keeping the rear end controlled over ripples and expansion joints. When the road turns twisty, this suspension confidence combines with strong braking to help the bike track securely through sweepers and changing surfaces.

Batwing Fairing, Tall Windshield, and Wind Management

The iconic Batwing fairing has been refined using computational fluid dynamics, wind-tunnel testing, and real-world miles to significantly enhance rider comfort. The new tall clear windshield is four inches higher than standard Street Glide models and reduces helmet buffeting by up to 60 percent. New fairing lowers with adjustable air vents and larger, adjustable fork-mounted air deflectors let you manage airflow to suit the day. A fairing skirt optimized to work with the lowers further calms turbulence around the cockpit. The outcome is a quieter, more stable pocket of air that reduces fatigue and keeps you focused on the next horizon.

King Tour-Pak® Luggage and 4.9 cu ft Storage

Touring demands practical storage that is easy to access on the move. The Street Glide® Ultra delivers 4.9 cubic feet of combined capacity—more than twice that of a standard Street Glide. The hard-shell King Tour-Pak® comes standard with a robust passenger back pad and armrests, offering both support and convenience. Fairing cubbies keep smaller items handy, while the large saddlebags secure your essentials for multi-day travel. Finished saddlebag guards match the bike and help protect the bodywork in the event of a tip-over. It all adds up to smart packing with fewer compromises, whether you are commuting during the week or crossing state lines on the weekend.
