The 2025 Harley-Davidson® Street Glide® Ultra in Houston, TX
The 2025 Harley-Davidson® Street Glide® Ultra is built for long-distance touring. This model offers a combination of high-performance engineering, rider comfort, and advanced technology. Let’s find out what makes this bike perfect for long-haul journeys.
Engine and Performance
The Milwaukee-Eight® 117 V-Twin engine delivers high output and efficiency. With a displacement of 117 cubic inches, the engine is designed to provide strong torque and acceleration. The bore measures 4.075 inches, and the stroke measures 4.5 inches. A compression ratio of 10.3:1 enhances combustion efficiency for improved performance.
This engine generates 105 horsepower at 4,600 rpm and 130 ft-lb of torque at 3,250 rpm. A liquid-cooled cylinder head system and a centrally located radiator improve thermal management, keeping the engine at optimal operating temperatures during extended rides or in high-heat conditions.
Chassis and Suspension
The steel frame of the 2025 Harley-Davidson® Street Glide® Ultra balances strength and controlled flexibility, ensuring stability and responsiveness. The front suspension features a 49mm Dual Bending Valve fork, which optimizes both compression and rebound damping for a controlled ride.
The rear suspension is equipped with SHOWA® dual outboard emulsion shocks, providing three inches of travel for smooth performance over varying road conditions. A hydraulic preload adjustment allows riders to modify suspension settings to accommodate changes in passenger weight and cargo load without requiring tools.
Braking System
The front braking system includes dual 32mm four-piston fixed axially mounted calipers with dual floating rotors. The rear braking system consists of a single four-piston axially mounted caliper with a fixed rotor. These braking components are designed to provide reliable stopping power under heavy loads. A standard Anti-Lock Braking System (ABS) helps prevent wheel lock-up during emergency braking. This system ensures stability and control across different road surfaces.
Dimensions and Weight
The overall length of the 2025 Harley-Davidson® Street Glide® Ultra is 102 inches, while the width measures 38.6 inches. The laden seat height is 26.9 inches, and the ground clearance is 5.3 inches. The wheelbase extends 64 inches, contributing to stability on highways.
In running order, the motorcycle weighs 866 pounds. The fuel tank holds 6 gallons, and the oil capacity, including the filter, is 5 quarts.
Aerodynamics and Wind Deflection
The batwing fairing of the 2025 Harley-Davidson® Street Glide® Ultra has been engineered using computational fluid dynamics (CFD) and wind tunnel testing. This aerodynamic refinement results in a 60 percent reduction in helmet buffeting, allowing for a smoother riding experience.
A taller windshield improves wind deflection, reducing fatigue from prolonged exposure to air resistance. Adjustable air vents in the fairing lowers provide additional control over airflow. Larger fork-mounted air deflectors contribute to improved wind management, ensuring rider comfort in various riding conditions.
Comfort and Ergonomics
The two-up touring seat is designed to support rider and passenger posture, with an ergonomic shape that slightly rotates the rider’s hips forward. This design reduces spinal pressure and improves overall comfort on long rides.
Heated grips offer additional comfort in cooler temperatures. The King Tour-Pak® luggage carrier includes a passenger backrest and armrests, enhancing passenger support. A combined 4.9 cubic feet of storage space between the King Tour-Pak® and saddlebags provides sufficient capacity for travel essentials.
Infotainment and Technology
The Skyline™ OS infotainment system is integrated into the 2025 Harley-Davidson® Street Glide® Ultra. The screen is glove-friendly and supports voice recognition for hands-free operation. Standard navigation, Bluetooth® connectivity, and Apple CarPlay® integration allow access to maps, music, and communication features.
A high-quality two-speaker audio system is built into the motorcycle. The speakers are positioned within the fairing and King Tour-Pak® carrier, providing an even distribution of sound. This system is designed to deliver clear audio at highway speeds.
Lighting and Visibility
An LED headlamp provides bright illumination, improving visibility in low-light environments. The LED turn signals and brake lights increase visibility for surrounding traffic, enhancing overall safety.
Safety and Rider Assistance
A suite of Harley-Davidson® Rider Safety Enhancements is integrated into the 2025 Harley-Davidson® Street Glide® Ultra. The Cornering Enhanced Anti-Lock Braking System (C-ABS) maintains braking control when leaning into turns. The Cornering Enhanced Traction Control System (C-TCS) adjusts power delivery to prevent loss of traction on different surfaces.
The Drag-Torque Slip Control System (DSCS) reduces rear-wheel lockup during rapid deceleration. The Vehicle Hold Control (VHC) assists in preventing unintended rollback when stopping on an incline. A Tire Pressure Monitoring System (TPMS) continuously monitors tire pressure, alerting the rider to any changes that could affect performance.
