The 2025 Harley-Davidson® Tri Glide® Ultra is engineered for extended touring with the added control and support of a three-wheel configuration. It maintains the traditional touring features Harley-Davidson® riders expect but adapts them to a platform designed for long-haul capability, cargo efficiency, and rider control. The 2025 Harley-Davidson® Tri Glide® Ultra serves as a full-dresser trike intended for highway use, cross-state travel, and year-round usability.
Powertrain and Torque Capacity
The 2025 Harley-Davidson® Tri Glide® Ultra relies on the Milwaukee-Eight® 114 engine to deliver 120 lb-ft of torque through an air- and oil-cooled V-Twin platform. This configuration provides steady power at highway speeds and maintains drivability in low-speed traffic. Engine performance remains stable under load, supporting passenger transport and fully loaded cargo without compromising throttle control. Torque delivery is distributed evenly across the RPM range, ensuring smooth acceleration and consistent cruising behavior.
Fuel economy is rated at 42 miles per gallon. This efficiency complements the trike’s long-distance touring function. The trike’s fuel management system pairs well with the engine, maintaining usable range while reducing heat and emissions during urban travel.
Suspension Configuration for Load and Comfort
The 2025 Harley-Davidson® Tri Glide® Ultra uses dual bending valve technology in the front suspension. This design improves damping characteristics under both compression and rebound. It adapts to uneven surfaces while reducing input to the rider.
The rear suspension uses emulsion technology with a single-knob preload adjuster. This system enables on-the-fly modifications to preload pressure without tools or disassembly. The suspension maintains consistent chassis balance, reducing squat under acceleration and minimizing wallow during cornering.
This design is intended to offer predictable handling under full touring conditions. Combined with the trike’s weight distribution, the suspension package provides a stable and compliant ride.
Wheel Geometry and Ground Support
The front wheel measures 19 inches, while the rear wheels are 18 inches in diameter. This configuration gives the trike a stable profile with no change to seat height. The wheel selection supports long-term durability, appropriate for both paved highways and uneven rural routes.
Cast aluminum construction is used for the wheels. The wheel design is built to manage the additional stress of three-wheel touring, with surface treatment options depending on the selected trim. Black finishes are standard on the new Black Trim, while Chrome Trim options retain a polished aesthetic.
Fairing, Weather Control, and Aerodynamics
The 2025 Harley-Davidson® Tri Glide® Ultra includes a full Batwing fairing with split-stream vents. These vents reduce helmet buffeting by equalizing air pressure behind the windshield. A tall windshield offers upper body protection for both the rider and passenger. Integrated fairing lowers help reduce leg fatigue during high-speed travel or in colder temperatures.
These lowers are mounted to a blacked-out engine bar and do not interfere with foot placement. This arrangement allows for better wind control and overall rider protection without compromising ergonomic access.
Lighting, Paint Options, and Visibility
LED lighting is standard on the 2025 Harley-Davidson® Tri Glide® Ultra. This includes headlamps and fog lamps. These units produce strong forward projection for night riding and enhanced daytime visibility. The LED array is integrated into the fairing and front structure, contributing to electrical efficiency and longevity.
The 2025 Harley-Davidson® Tri Glide® Ultra is offered in two trims. The Chrome Trim includes Billiard Gray, Vivid Black, Iron Horse Metallic, and a two-tone Whiskey Fire and Vivid Black. The Black Trim expands color options with Atlas Silver Metallic and Mystic Shift. Mystic Shift is a factory custom paint with multiple hues, including gunmetal, purple, blue, and orange tones, depending on light conditions. All finishes are clear-coated for durability and are integrated with Scorched Chrome or black badging, depending on the trim.
Storage and Cargo Access
The combined storage capacity of the trunk and King Tour-Pak® is 6.8 cubic feet. The trunk is weather-sealed and features a locking latch system. This provides security and environmental protection for luggage, gear, and essentials.
The King Tour-Pak® is equipped with a soft liner and interior lighting. This improves visibility during low-light loading and reduces abrasion during travel. The luggage compartment opens from the rear, allowing access without dismounting the trike.
This cargo system is integrated into the chassis for structural balance. Storage does not interfere with passenger space and does not affect the trike’s center of gravity.
Infotainment and Integrated Controls
The 2025 Harley-Davidson® Tri Glide® Ultra is equipped with the Boom!™ Box GTS system. This system is managed through a 6.5-inch touchscreen. The interface allows access to GPS navigation, Bluetooth® pairing, audio control, and system settings. The display is sunlight-readable and features a simple menu layout for use while stationary.
Audio is distributed through four 25-watt speakers. These speakers are mounted in the fairing and Tour-Pak® and support FM radio, wired audio, Bluetooth® streaming, and satellite radio compatibility. Audio balance is tuned for three-wheel acoustics, which differ from standard motorcycle applications due to seating position and cargo shape.
The electric reverse system is operated through a single-button control. This feature allows the rider to reverse the trike under power without manual pushback. The system is effective for navigating inclined surfaces and tight parking spaces.
Rider Safety Enhancements
The 2025 Harley-Davidson® Tri Glide® Ultra includes a full Rider Safety Enhancements suite. These systems are designed to assist the rider during acceleration, braking, and deceleration in real time. Each system operates passively until activated by specific road conditions or rider input.
The Anti-lock Brake System prevents wheel lock during sudden or forceful braking in a straight line. It is calibrated for trike behavior, which differs from two-wheel motorcycles due to the additional rear wheel and lateral force distribution.
Electronic Linked Braking applies brake force to both front and rear wheels when a single brake control is engaged. This improves braking performance and reduces stopping distance under certain conditions.
The Traction Control System limits excessive rear-wheel spin during straight-line acceleration. It is useful in low-grip environments such as wet pavement or road debris.
The Drag-Torque Slip Control System manages rear-wheel slip during deceleration. This function is most effective during abrupt downshifts or throttle closures on slippery surfaces. It stabilizes the trike by controlling engine-brake torque and smoothing transitions.
Cornering enhancements include systems that adjust behavior based on lateral acceleration. Cornering Enhanced ABS, Linked Braking, and Traction Control all use internal sensors to monitor lean and grip levels during a turn. Brake pressure, throttle response, and traction thresholds are altered automatically to maintain a consistent cornering line.
Model Structure and Trim Strategy
The 2025 Harley-Davidson® Tri Glide® Ultra is available in two primary trims. The Chrome Trim retains the brand’s traditional design language with polished components and contrasting body panels. The Black Trim offers a darkened profile with black finishes on wheels, engine covers, and trim pieces.
Both trims share identical mechanical specifications. The trim differences are cosmetic and do not affect performance or safety system functionality. This gives riders aesthetic flexibility without feature compromise.
