The 2025 Harley-Davidson® Street Glide® Ultra is engineered for long-distance touring. The motorcycle integrates advanced aerodynamics, enhanced comfort features, and modern technology for a stable and controlled riding experience.
The redesigned batwing fairing improves aerodynamics. Computational fluid dynamics (CFD) software and wind tunnel testing were used to optimize airflow and reduce helmet buffeting by up to 60% compared to previous designs.
The Milwaukee-Eight® 117 engine powers the 2025 Harley-Davidson® Street Glide® Ultra. The V-Twin engine delivers increased horsepower and torque compared to earlier models. Liquid-cooled cylinder heads and a centrally mounted radiator regulate engine temperatures. The 117 cubic-inch displacement provides a balance of power and efficiency for highway cruising and city riding.
The SHOWA® dual outboard emulsion technology shocks improve rear suspension performance. Three inches of rear travel allow for consistent and responsive handling. A remote hydraulic preload adjustment system enables fine-tuning of the suspension for different loads. The 49mm dual bending valve front forks enhance stability and control.
The two-up comfort seat is designed for ergonomic support. The seat geometry adjusts the rider’s hip positioning to alleviate spinal pressure. The motorcycle offers 4.9 cubic feet of total storage capacity. The storage system includes hard-shell saddlebags, a King Tour-Pak® luggage carrier, and fairing compartments. Lockable and weather-sealed compartments protect stored items from environmental conditions.
The 12.3-inch touchscreen color TFT display integrates the Skyline™ OS. The interface provides access to infotainment functions, real-time navigation, and ride mode adjustments. A hands-free voice recognition system enables control over essential functions without manual input.
The brakes with ABS increase braking stability. The system prevents wheel lockup during sudden braking scenarios. Vehicle Hold Control (VHC) prevents the motorcycle from rolling backward on inclines and declines. Traction control, drag-torque slip control, and cornering-enhanced ABS optimize stability in different riding conditions.
The LED lighting system enhances visibility in low-light conditions. The LED headlamp provides a focused and wide-beam output. The lighting system includes LED turn signals, brake lights, and tail lamps for increased road presence.
A six-gallon fuel tank provides extended riding range. The Milwaukee-Eight® 117 engine features an Electronic Sequential Port Fuel Injection (ESPFI) system for improved efficiency. The combination of fuel capacity and engine efficiency supports long-distance travel without frequent refueling.
The motorcycle features factory-applied paint with corrosion-resistant coatings. The finishes include high-gloss and matte options. Chrome and blacked-out trim packages allow for aesthetic customization.
