The 2025 Harley-Davidson® CVO™ Road Glide® ST is engineered with performance-focused components, advanced electronic systems, and lightweight materials shaped by competition influences. Its construction centers on efficient power delivery, reduced mass, and rider-adjustable systems designed to support stable handling. Every aspect of the model is designed with observable function in mind, from its forged carbon fiber elements to its precision-calibrated suspension. This overview details the main technical features and specifications that define the motorcycle and its operational characteristics.
Engine Output and Performance Configuration
The motorcycle is powered by the Milwaukee-Eight® 121 High Output V-twin engine that produces 127 horsepower and 145 ft-lb of torque. This engine incorporates a high-performance camshaft, a Heavy Breather Intake, and a raised rev limit of 5,900 rpm to support higher speed ranges. The airflow system is designed to increase engine efficiency during strong acceleration. The exhaust structure uses lightweight titanium mufflers that reduce overall mass and improve gas flow, contributing to a consistent power curve during extended operation.
Fuel economy is measured at 44 mpg, which supports longer-distance operation with reduced refueling frequency. The powertrain is engineered to maintain consistent output under varying load conditions without compromising engine stability. The combination of peak torque and horsepower values allows the rider to access strong acceleration at moderate throttle input. This contributes to predictable forward drive in standard and performance modes. The model’s laden seat height of 26.7 inches provides a position that supports control during quick acceleration and slow-speed maneuvering.
Suspension Systems and Handling Capabilities
The 2025 Harley-Davidson® CVO™ Road Glide® ST uses a suspension configuration that is fully adjustable. The SHOWA® 47 mm inverted front forks provide 4.6 inches of travel and allow adjustments to compression, rebound, and preload. This enables the rider to calibrate the front end for preferred firmness or responsiveness. The forks help stabilize the motorcycle during braking and corner entry and maintain a consistent feel over uneven surfaces.
The rear suspension consists of dual outboard SHOWA® Remote Reservoir shocks with three inches of travel. These shocks are positioned between the saddlebags and rear fender and are engineered to be characterized for consistent damping. This separation supports shock performance during long periods of operation and during conditions that require repeated or forceful shock, a character that remains predictable during higher speeds and lean angles with minimal interruption to stability.
The mini-boards installed on the model provide foot support without reducing lean angle capability. This maintains ergonomic stability while preserving the motorcycle’s ability to manage tighter turns or aggressive directional changes.
Weight Reduction and Structural Innovations
The motorcycle uses several lightweight materials that support mass reduction. The forged carbon fiber front fender replaces the typical steel version and reduces unsprung weight. This material choice improves responsiveness during steering input and contributes to a more stable feel while cornering.
Cast aluminum wheels also reduce unsprung mass and support improved handling accuracy. These wheels are paired with dual floating brake rotors that dissipate heat efficiently during heavy braking. Heat control is essential for consistent braking performance because it reduces the potential for fade during repeated stops.
The solo seat design is lightweight and features a steep back that supports the rider during strong acceleration and cornering. This seat shape helps maintain a planted riding posture, which is useful during performance-oriented operation. The ergonomics are further supported by tall risers and a moto bar that allow personalized adjustment. Riders can fine-tune reach and posture to match individual control preferences. A Flat-Out bar is integrated as a durable engine guard that protects critical components in the event of a low-speed tip-over without interfering with the limited-edition paint.
Display Technology and Functional Interfaces
The 2025 Harley-Davidson® CVO™ Road Glide® ST features a 12.3-inch TFT display supported by the Skyline™ OS system. The display provides instrumentation, ride mode access, navigation, and integration with the Rockford Fosgate® Stage II audio system. Traffic and weather overlays appear directly on the screen for enhanced situational awareness. Visual clarity and touchscreen functionality allow the rider to manage settings efficiently.
The interface is engineered to present data in an organized layout that minimizes distractions. The large screen size allows multiple data fields to be displayed simultaneously, which supports quick-glance readability. The OS design ensures smooth transitions between functions such as navigation, ride mode selection, and audio adjustment.
Ride Modes and Electronic Adjustments
Eight ride modes are available. Among these are Track and Track Plus modes, which are intended for closed-course use. These performance modes adjust throttle response, traction control parameters, and braking behavior. The remaining modes refine stability and comfort depending on riding style, road type, and environmental conditions. Each mode controls power delivery and safety system sensitivity to suit varied operational needs.
Ride modes respond to rider input without requiring extensive configuration, which ensures that power and traction settings can be changed efficiently. The rider can switch between modes through the TFT display interface.
Safety Technologies and Cornering Enhancements
The 2025 Harley-Davidson® CVO™ Road Glide® ST includes Rider Safety Enhancements suite. This collection of systems intervenes when traction is compromised or when braking forces exceed available grip. The standard Anti-lock Brake System prevents wheel lock during straight-line braking events. Electronic Linked Braking applies balanced pressure between the front and rear brakes to maintain stability. During lighter braking or slower speeds, the linking effect is minimized to maintain natural brake feel.
The Traction Control System prevents the rear wheel from spinning during acceleration. Drag-Torque Slip Control helps prevent rear-wheel slip caused by abrupt downshifts or sudden throttle closure on slick surfaces. Vehicle Hold Control keeps the motorcycle stationary on inclines until the rider applies throttle, which simplifies hill starts. Tire Pressure Monitoring alerts the rider to low or high tire pressure to help maintain performance and tire longevity.
The cornering-enhanced systems expand these functions when the motorcycle is leaned. Cornering ABS, Cornering Linked Braking, Cornering Traction Control, and Cornering Drag-Torque Slip Control all adjust based on lean angle. These systems stabilize braking and acceleration forces while the motorcycle is turning. Their purpose is to assist riders in maintaining a controlled path and reducing the chances of traction loss during lean angles.
Integrated Invitation to Experience the Model
For riders interested in experiencing the operational characteristics of this model, scheduling a test ride provides a direct way to evaluate its power delivery, suspension precision, and electronic safety features. The combination of the Milwaukee-Eight® 121 High Output engine, adjustable SHOWA® suspension, and advanced rider technology presents a clear demonstration of the motorcycle’s performance behavior. Test rides offer a practical opportunity to observe how the ride modes adjust throttle response and traction control. Riders can also experience the functioning of the cornering systems and the clarity of the 12.3-inch display under standard daylight conditions. Those ready to explore these features in person can arrange a test ride through Raging Bull Harley-Davidson® close to Raleigh, NC.
