Suspension and Ride Quality
The suspension system of the 2025 Harley-Davidson® Tri Glide® Ultra is designed to maintain stability while providing adaptability for different riding conditions. The front suspension uses dual bending valve technology, improving damping response across varying road surfaces. This setup helps reduce front-end dive under braking and contributes to consistent steering performance.
The rear suspension features emulsion technology with a single-knob preload adjustment. This allows quick modification of the rear suspension load setting to accommodate changes in passenger weight or cargo. The design simplifies fine-tuning and supports comfort and control over extended distances. Combined, these suspension components contribute to balanced handling and reduced rider fatigue.
Aerodynamics and Structural Design
The 2025 Harley-Davidson® Tri Glide® Ultra uses a full Batwing fairing with integrated split-stream vents and a tall windshield. This system is built to manage airflow effectively, reducing buffeting for both rider and passenger. The lower fairings are mounted around a blacked-out engine guard, helping to deflect wind and moisture while also improving aerodynamic stability.
The trike’s frame geometry and wheel layout provide structural stability with predictable handling. The 19-inch front wheel and 18-inch rear wheels establish a wide stance that enhances balance and cornering precision without increasing the seat height. This maintains accessibility and rider confidence during stops and low-speed maneuvers.
The King Tour-Pak® luggage carrier and integrated trunk provide a combined cargo capacity of 6.8 cubic feet. Both compartments are weatherproof and lockable, featuring interior lighting and a lined interior surface for added protection. The construction supports practical use for touring and everyday storage requirements.
Trim and Color Configuration
The 2025 Harley-Davidson® Tri Glide® Ultra is available in two trim packages: Chrome and Black. The Chrome Trim reflects the traditional Harley-Davidson® touring appearance with polished accents and color options that include Billiard Gray, Vivid Black, Iron Horse Metallic, and Whiskey Fire/Vivid Black.
The Black Trim version introduces darker styling elements for a more contemporary appearance. It features black finishes on the powertrain, wheels, and other visible components. Available colors include Billiard Gray, Vivid Black, Atlas Silver Metallic, Iron Horse Metallic/Vivid Black, Whiskey Fire/Vivid Black, and the Harley-Davidson® Factory Custom color Mystic Shift. The Mystic Shift paint is multi-tonal, transitioning between dark gunmetal, purple, blue, and a subtle orange hue under full sunlight.
Lighting and Visibility
The 2025 Harley-Davidson® Tri Glide® Ultra uses an LED lighting system for both primary and auxiliary illumination. The LED headlamp and fog lamps deliver bright, consistent coverage designed for improved visibility and recognition in varied weather or lighting conditions. The King Tour-Pak® luggage carrier includes integrated lighting for enhanced rear visibility and a distinct appearance at night.
All lighting components are engineered to reduce power draw while maintaining reliable brightness and longevity. This system increases visibility for the rider and ensures other motorists can detect the trike more easily.
Infotainment and Control Systems
The 2025 Harley-Davidson® Tri Glide® Ultra includes the Boom!™ Box GTS infotainment system, which integrates navigation, audio control, and connectivity in one interface. The 6.5-inch touchscreen display is responsive and easy to operate while riding. It supports Bluetooth® connections for smartphones and audio devices, as well as USB and satellite radio compatibility.
The four-speaker sound system, rated at 25 watts per speaker, delivers balanced clarity at both low and highway speeds. The system’s design ensures steady performance under high-vibration conditions common to touring motorcycles.
The infotainment system also provides access to the Harley-Davidson® Rider Safety Enhancements menu, where certain rider assistance functions can be adjusted or monitored. The inclusion of an electric reverse drive allows the rider to back up the trike using motor-assisted power, making parking and repositioning manageable in confined or sloped areas.
Rider Safety Enhancements
The 2025 Harley-Davidson® Tri Glide® Ultra incorporates the comprehensive Rider Safety Enhancements suite from Harley-Davidson®, designed to assist the rider in maintaining control during acceleration, braking, and cornering. Each component functions automatically, using sensors to monitor wheel speed, traction, and vehicle dynamics.
The Anti-lock Brake System prevents wheel lock-up under heavy braking, supporting straight-line control. Electronic Linked Braking distributes braking force between the front and rear wheels to maintain balanced deceleration. This feature automatically adjusts the proportion of brake pressure depending on conditions, minimizing abrupt handling changes.
The Traction Control System reduces wheel spin when accelerating on low-traction surfaces, helping the trike maintain steady forward motion. The Drag-Torque Slip Control System limits rear-wheel slip under deceleration, particularly during abrupt downshifts or when throttle input is reduced quickly on wet or uneven roads.
Additional cornering-specific systems enhance safety further. The Cornering Enhanced Anti-lock Brake System (C-ABS) adjusts braking pressure in response to lateral acceleration. The Cornering Enhanced Electronic Linked Braking (C-ELB) modifies brake force distribution based on cornering behavior to maintain the intended path of travel. The Cornering Enhanced Traction Control System (C-TCS) provides consistent traction by regulating power delivery when accelerating through curves. Together, these features form an integrated safety structure that supports predictable handling and braking stability.
Comfort and Ergonomic Efficiency
The 2025 Harley-Davidson® Tri Glide® Ultra is equipped for long-distance comfort through both structural and design-based refinements.
