2025 Harley-Davidson® Street Glide® near Greenville, SC
The 2025 Harley-Davidson® Street Glide® combines established design elements with updated mechanical and technological components. It incorporates a liquid-cooled V-twin engine designed for consistent power delivery and thermal management. The motorcycle integrates modern rider aids and safety systems, enhancing performance and control while maintaining the brand’s recognizable style.
Engine Performance and Mechanical Specifications
The Milwaukee-Eight® 117 V-twin engine drives the 2025 Harley-Davidson® Street Glide®, delivering 130 foot-pounds of torque and 105 horsepower from its 117 cubic inches of displacement. This powertrain incorporates liquid-cooled cylinder heads and a centralized radiator system to regulate engine temperature more efficiently. The cooling configuration supports steady thermal management during long rides and in high-heat environments. Compared to previous air-cooled models, this setup enhances performance stability under sustained load and variable operating conditions.
Fuel economy for the 2025 Harley-Davidson® Street Glide® is rated at approximately 44 miles per gallon, reflecting a balance between power output and efficiency. A high-performance intake system enhances airflow into the engine, increasing volumetric efficiency and throttle response. The rear suspension features hand-adjustable preload settings that accommodate variations in load, such as passenger weight or luggage, allowing riders to optimize ride quality and stability.
Seat height when loaded measures 26.4 inches, supporting a range of rider sizes and preferences. The frame and chassis are designed to complement the engine’s performance characteristics by maintaining structural rigidity and balance, which supports responsive handling and rider feedback.
Design and Aerodynamics
The 2025 Harley-Davidson® Street Glide® retains the classic Batwing fairing, a distinct design feature that has been refined using computational fluid dynamics (CFD). The revised shape improves aerodynamic efficiency by reducing wind resistance and minimizing turbulence around the rider’s helmet and upper body. This results in lower fatigue and improved comfort on long-distance rides.
The integrated LED lighting system is built into the fairing, enhancing both visibility and the motorcycle’s profile. The lighting elements combine daytime running lights with headlamps, which are designed for efficient illumination and low power consumption.
The wheels are sized at 19 inches in the front and 18 inches in the rear. These contrast-cut wheels provide structural strength while contributing to the bike’s handling dynamics. The larger front wheel aids stability and smoothness over road irregularities, and the rear wheel size supports traction and acceleration.
The one-piece seat is designed for ergonomic support during extended rides. Its construction balances cushioning with firmness to reduce rider fatigue without compromising control. Available paint finishes include nine options, ranging from solid colors to custom Factory Custom styles that offer specialized graphics and finishes, such as multi-shade shifting paint that changes color based on lighting conditions.
Technology Integration
The 2025 Harley-Davidson® Street Glide® features a 12.3-inch color TFT touchscreen display. This display offers clear visibility in various lighting environments and provides access to navigation, audio controls, and system status indicators. The interface is designed to respond quickly to input and organize information for efficient rider interaction.
The motorcycle includes three standard ride modes—Road, Sport, and Rain—each preset with specific adjustments for throttle response, traction control, and braking characteristics. Additionally, a customizable mode allows the rider to configure these parameters manually, adjusting settings for specific road conditions or personal preference.
Audio playback is delivered through fairing-mounted speakers powered by a 200-watt four-channel amplifier. The audio system is designed to maintain clarity and volume across a range of speeds and environmental noise levels, supporting media streaming or voice commands.
Rider Safety Systems
Safety features on the 2025 Harley-Davidson® Street Glide® consist of several electronic control systems intended to enhance stability and braking performance. The Anti-lock Brake System (ABS) prevents wheel lock-up during hard braking, helping maintain directional control. Electronic Linked Braking (ELB) distributes braking force between front and rear wheels when either brake is applied, improving stopping efficiency and balance.
The Traction Control System (TCS) limits rear-wheel spin during acceleration, which aids in maintaining grip on variable surfaces. The Drag-Torque Slip Control System (DSCS) monitors and controls rear-wheel slip during engine braking or downshifting, particularly on slippery roads. These systems operate automatically and continuously without rider intervention.
Cornering Rider Safety Enhancements adjust ABS, ELB, and TCS functions based on the motorcycle’s lean angle. This ensures braking and traction control are optimized when the bike is cornering, reducing the risk of wheel slip or lock under lateral forces.
Vehicle Hold Control (VHC) assists with hill starts by holding brake pressure when the rider releases the brake lever or pedal, preventing rollback. This system is engaged through a brief brake application at a stop and is deactivated by throttle input.
A Tire Pressure Monitoring System (TPMS) continuously monitors tire pressure and alerts the rider to deviations from recommended levels, supporting proper tire maintenance and consistent handling.
