The 2025 Harley-Davidson® Street Glide® combines established touring design with updated engineering and modern technology. It delivers consistent performance with a focus on rider control, comfort, and integrated systems that support a wide range of riding conditions. The model reflects technical refinement in both powertrain and chassis, complemented by an advanced electronics suite.
Engine Performance and Cooling System
Central to the 2025 Harley-Davidson® Street Glide® is the Milwaukee-Eight® 117 V-Twin engine, measuring 117 cubic inches. The engine produces 105 horsepower and 130 foot-pounds of torque, providing steady power delivery optimized for touring applications. This version incorporates liquid-cooled cylinder heads with a centrally mounted radiator. The liquid cooling helps maintain engine temperature stability, especially during long rides or in warmer climates, reducing the risk of overheating and improving overall engine efficiency.
The engine intake system is designed to maximize airflow, using a high-performance touring intake that increases internal volume. This enhances throttle response and engine performance across a broad RPM range.
Design and Aerodynamic Features
The 2025 Harley-Davidson® Street Glide® continues to use the iconic Batwing fairing, which has been engineered with computational fluid dynamics (CFD) to improve airflow and reduce wind buffeting. This aerodynamic optimization supports rider comfort during extended highway riding by minimizing turbulence around the rider's head and torso. The fairing integrates LED lighting into its structure, enhancing visibility on the road while maintaining a cohesive and streamlined appearance.
The motorcycle rides on 19-inch front and 18-inch rear wheels with contrast-cut finishes that add to the model's stance and road presence. These wheel sizes balance maneuverability with stability at higher speeds. The seat is a one-piece design with a height of 26.4 inches when loaded. This seating arrangement supports ergonomic positioning and aims to reduce rider fatigue on long trips.
Available paint options include nine premium finishes, which include three Factory Custom schemes with unique visual effects. Among these, Mystic Shift presents a color-shifting effect that changes depending on light exposure. Other custom schemes use classic flame motifs. Riders may select between chrome and blacked-out engine finishes, offering options that complement personal style preferences.
Integrated Technology and Controls
A prominent feature of the 2025 Harley-Davidson® Street Glide® is the 12.3-inch color TFT touchscreen display. This interface centralizes navigation, media, and system settings into a clear and accessible format. The touchscreen is designed to provide intuitive control over infotainment and ride information, improving usability without detracting from rider focus.
The motorcycle offers three predefined ride modes. Road mode provides balanced performance for general use. Sport mode adjusts throttle mapping and traction control settings for a more responsive ride. Rain mode prioritizes stability and traction for wet or low-grip conditions. There is also a customizable mode that allows riders to set individual parameters according to specific preferences.
Audio is delivered through fairing-mounted speakers powered by a 200-watt four-channel amplifier. This system produces clean and balanced audio across low, mid, and high frequencies, designed to perform well in open-air riding environments.
Safety Systems and Rider Assistance
The 2025 Harley-Davidson® Street Glide® includes a comprehensive set of rider safety technologies designed to assist in maintaining control during various riding scenarios. The anti-lock braking system (ABS) helps prevent wheel lockup during braking, maintaining directional stability, especially in emergency stops. Electronic Linked Braking (ELB) distributes braking force between front and rear wheels based on rider input, enhancing braking efficiency.
Traction Control System (TCS) prevents rear wheel spin during acceleration on low-traction surfaces. Drag-Torque Slip Control System (DSCS) reduces rear wheel slip and locking during sudden deceleration or downshifting, which is particularly useful on slippery roads. Vehicle Hold Control (VHC) keeps the bike stationary on inclines by maintaining brake pressure after the rider releases the brake lever or pedal, simplifying hill starts.
Additional safety features account for the bike’s behavior while cornering. Cornering Enhanced ABS and Electronic Linked Braking adjust braking pressure based on lean angle to prevent wheel slip while maintaining the rider’s intended path. Cornering Enhanced Traction Control and Drag-Torque Slip Control extend these adjustments to acceleration and deceleration during lean angles, increasing stability in turns.
The tire pressure monitoring system (TPMS) provides real-time feedback on tire inflation, alerting the rider to pressure deviations that could affect handling and tire life.
Functional Design and Customization
The 2025 Harley-Davidson® Street Glide® integrates functional design elements aimed at maximizing touring efficiency and rider convenience. Suspension settings are easily adjustable, providing riders with control over comfort and stability based on varying conditions.
Customization options are available to modify the bike’s appearance and performance. Riders may add aftermarket exhaust systems to adjust rumble and power characteristics or apply custom paint and graphics to personalize the motorcycle’s look. The choice between chrome and black finishes extends to various components, allowing fine-tuning of aesthetic presentation without sacrificing technical performance.
