Power Delivery Through Milwaukee-Eight® Engineering
The liquid-cooled Milwaukee-Eight® 117 V-Twin engine defines the power characteristics of the 2025 Harley-Davidson® Street Glide® with output measured at 130 foot-pounds of torque and 105 horsepower. The liquid cooling system includes cylinder head cooling and a center-mounted radiator that moderates temperatures during high load conditions. This approach maintains controlled combustion and stable engine behavior during highway speeds, stop-and-go traffic, steep inclines, or extended warm-weather operation. The engine design is focused on responsive acceleration and consistent pull with an efficient fuel economy rating of 44 miles per gallon. These operational figures align with long-distance touring expectations and support continuous riding across varying road conditions.
The high-flow touring intake increases internal volume to support higher airflow. This optimization assists throttle response and sustained power delivery by ensuring the engine has adequate breathing capacity across a broad rpm range. During acceleration or during load changes such as passing maneuvers or carrying luggage, the intake system helps maintain predictable power output and controlled engine response.
Suspension Setup With Adjustable Rear Technology
The rear suspension uses quickly adjustable hand-operated preload controls. This system allows riders to fine-tune suspension behavior for different loads and road surfaces. Adjustments accommodate additional passenger weight, luggage, or road irregularities, resulting in improved balance. The ability to alter preload without tools supports tuning based on changing riding demands. This contributes to more consistent chassis behavior during corner entries, long-distance cruising, or surfaces with varying smoothness.
Aerodynamic Structure With Updated Batwing Fairing
The batwing fairing remains a defining feature of the 2025 Harley-Davidson® Street Glide®. It is shaped using computational fluid dynamics, which provides refined airflow distribution across and around the rider. These improvements reduce turbulence that commonly affects long-distance comfort and rider stability at higher speeds. The updated shape contributes to predictable airflow management and reduced fatigue during extended hours of riding.
The fairing includes integrated LED signature lighting that is built directly into the surrounding bodywork. This integration creates a clean visual profile and improves lighting performance. LED lighting increases forward visibility and allows approaching traffic to better identify the motorcycle. The placement within the fairing maintains aerodynamic continuity with no additional external housing.
Chassis Elements and Wheel Construction
The 2025 Harley-Davidson® Street Glide® uses contrast-cut wheels that measure 19 inches in the front and 18 inches in the rear. This wheel configuration enhances the motorcycle’s stance while contributing to predictable handling characteristics. The front wheel supports stable turn-in behavior, and the rear wheel assists traction during acceleration and corner exits. The wheel sizes work in coordination with the suspension and overall chassis geometry to create steady handling across varied speeds and road textures.
The seat design uses a one-piece structure that complements the motorcycle’s silhouette and supports long-mile comfort. Its construction helps distribute rider weight in a balanced manner that reduces fatigue. This contributes to sustained comfort on long touring routes without altering the motorcycle’s profile or compromising stability.

Infotainment With Large-Format TFT Display
A 12.3-inch color TFT touchscreen provides access to navigation functions, audio settings, vehicle information, and ride adjustments. The clarity of the display supports visibility in various lighting conditions. The touchscreen format allows the rider to interact directly with the interface in a straightforward manner that does not require additional physical controls for primary functions. This consolidates essential touring information into one centralized system.
The audio system features fairing-mounted speakers powered by a 200-watt four-channel amplifier rated at 50 watts per channel. This configuration produces clear audio across low, mid, and high frequencies even during higher-speed travel. The speakers are integrated into the fairing design to maintain cohesive aerodynamics and reduce the need for external housings.
Ride Modes and Rider-Controlled Tuning
The 2025 Harley-Davidson® Street Glide® includes 3 pre-programmed ride modes identified as Road, Sport, and Rain, along with a customizable mode for rider-defined settings. Each mode adjusts power delivery and electronic intervention levels. Road mode provides balanced characteristics, Sport increases responsiveness, Rain softens power application for low-traction surfaces, and the customizable option gives riders control over behavior based on their preferred setup. These modes allow the motorcycle to adapt to changing conditions and riding preferences without requiring mechanical modification.
Rider Safety Enhancements Integrated Into Core Systems
The 2025 Harley-Davidson® Street Glide® includes Harley-Davidson® Rider Safety Enhancements, which support stability, traction, and braking control. These systems assist the rider during acceleration, deceleration, turning, and surface transitions. ABS prevents wheel lock during straight-line braking. Electronic Linked Braking distributes braking effort between wheels to maintain stability during braking inputs. Traction control moderates rear-wheel slip during acceleration on low-traction surfaces. Drag-Torque Slip Control reduces rear-wheel slip caused by sudden downshifts or rapid throttle closure on wet or slippery pavement.
Cornering-enhanced variations adjust these systems based on lean angle. Cornering ABS modulates brake pressure to maintain traction during lean-assisted braking.
