The 2025 Harley-Davidson® Street Glide® Ultra is engineered specifically for two-up touring. This model combines a powerful engine with refined aerodynamics and integrated technology to support long-distance riding with comfort and control. Designed with decades of touring experience, the bike focuses on delivering performance, durability, and rider assistance features that improve handling and safety in a wide range of conditions.
Aerodynamic Engineering and Rider-Passenger Comfort
The 2025 Harley-Davidson® Street Glide® Ultra uses a revised Batwing fairing developed through computational fluid dynamics and wind-tunnel testing. The clear windshield is increased by four inches in height compared to the standard Street Glide® model. This adjustment reduces helmet buffeting by up to 60 percent. Additionally, the fairing lowers include adjustable air vents that work together with larger fork-mounted air deflectors.
The seating arrangement prioritizes ergonomics for extended rides with two riders. The redesigned two-up seat positions the rider’s hips slightly forward to reduce pressure on the lower spine, improving comfort over time. The passenger benefits from the King Tour-Pak® luggage carrier, which includes a sturdy backrest and armrests. The luggage carrier, combined with the fairing cubbies and saddlebags, provides a total storage volume of 4.9 cubic feet.
Powertrain and Suspension for Touring Performance
At the core of the 2025 Harley-Davidson® Street Glide® Ultra is the Milwaukee-Eight® 117 engine. This air-cooled V-twin engine delivers 105 horsepower and 130 foot-pounds of torque. Fuel efficiency is rated at 44 miles per gallon, balancing power and economy.
The suspension system includes SHOWA® dual outboard emulsion shocks with three inches of travel. Remote hydraulic preload adjustment allows riders to fine-tune suspension stiffness based on load and road conditions.
Aerodynamic components such as the fairing skirt complement the fairing lowers to manage wind flow and reduce turbulence around the bike.
Rider Safety Systems
The 2025 Harley-Davidson® Street Glide® Ultra integrates a comprehensive set of Rider Safety Enhancements designed to increase control and reduce risk during dynamic riding situations. The system includes a Cornering Enhanced Anti-lock Brake System (C-ABS) that adjusts braking pressure based on the motorcycle’s lean angle. This feature improves brake performance in turns by modulating pressure to prevent wheel lock without sacrificing stopping power.
Electronic Linked Braking (ELB) coordinates front and rear brake application when the rider uses the front brake lever. This linkage improves braking stability and performance during both standard and emergency braking scenarios. The Traction Control System (TCS) manages rear wheel slip during acceleration, helping to maintain traction on low-friction surfaces.
The Drag-Torque Slip Control System (DSCS) operates during deceleration and downshifting. This system reduces rear wheel slip caused by abrupt downshifts or rapid throttle closure, particularly on wet or slippery roads. Vehicle Hold Control (VHC) allows the bike to remain stationary on inclines without rider input on the brakes, facilitating smooth starts on hills.
Tire Pressure Monitoring System (TPMS) continuously monitors tire inflation and alerts the rider to deviations from the recommended pressure range.
Integrated Technology and Infotainment
The cockpit features a 12.3-inch TFT touchscreen display operating on Skyline™ OS platform. This interface provides high-resolution graphics for easy viewing of navigation, ride modes, and infotainment controls. The screen supports hands-free voice commands for navigation and communication. Riders can access functions such as “Find me a gas station” using natural language commands, allowing them to keep their focus on the road.
Connectivity options include Apple CarPlay®, enabling riders to integrate their smartphones with the bike’s infotainment system. Audio output is delivered through a 200-watt amplifier and speaker system, providing clear sound for music and navigation prompts. The interface also allows switching between four ride modes, adjusting the bike’s power delivery and electronic control systems to suit different riding environments.
Storage Capacity and Protective Features
Storage is a critical element of touring motorcycles, and the 2025 Harley-Davidson® Street Glide® Ultra provides ample capacity for gear and luggage. The King Tour-Pak® luggage carrier is a hard-shell design that integrates seamlessly with the bike’s lines and includes a cushioned backrest with armrests for the passenger. Large saddlebags provide additional volume and are secured with saddlebag guards.
Combined, the luggage compartments and storage cubbies offer 4.9 cubic feet of space, supporting extended trips where carrying capacity is essential.
