The 2025 Harley-Davidson® CVO™ Road Glide® ST is a production motorcycle influenced by the brand’s MotoAmerica® King of the Baggers™ racing program. It incorporates lightweight materials, track-inspired technology, and a Milwaukee-Eight® 121 High Output V-Twin engine, delivering performance features designed for speed, control, and precision handling. Every aspect of this model has been configured for optimal mechanical performance, from its suspension tuning to its braking systems, while retaining a balanced weight distribution for responsive maneuverability.
Milwaukee-Eight® 121 High Output Engine
The Milwaukee-Eight® 121 High Output engine is the most powerful engine used in a Harley-Davidson® production motorcycle, producing 127 horsepower and 145 foot-pounds of torque. It is equipped with a high-performance camshaft for efficient valve operation, a Heavy Breather intake to improve airflow, and a raised rev limit of 5,900 rpm to increase available power across the operating range. The titanium mufflers reduce overall mass while increasing exhaust flow, which supports higher performance output. The exhaust system produces a low, muscular rumble, complementing the engine’s mechanical efficiency. Fuel economy is rated at 44 mpg, offering an effective balance between output and efficiency.
Fully Adjustable Suspension System
The suspension on the 2025 Harley-Davidson® CVO™ Road Glide® ST has been designed for adjustability and consistent performance. At the front, SHOWA® 47 mm inverted forks provide 4.6 inches of travel and can be tuned for compression, rebound, and preload, allowing precise adjustment for different riding conditions. At the rear, dual outboard SHOWA® Remote Reservoir shocks offer three inches of travel and are mounted between the saddlebags and rear fender. These shocks maintain separation between oil and gas, ensuring reliable damping and preventing performance fade under sustained or aggressive use. This configuration allows the motorcycle to maintain stability through cornering, braking, and acceleration.
Race-Inspired Structural Components
A significant focus on weight reduction is evident in the use of advanced materials and component design. The forged carbon fiber front fender replaces a traditional steel part, reducing weight while providing durability. Cast aluminum wheels further lower unsprung mass, which improves steering response and acceleration. These wheels are paired with dual floating brake rotors that manage heat effectively under repeated braking cycles. The solo seat is designed with a steep rear section to provide support under hard acceleration and during lean-intensive cornering. P&A tall risers and a moto-style handlebar allow for ergonomic adjustments, while a Flat-Out bar engine guard offers impact protection with minimal added weight.
Braking Systems and Stopping Control
Braking performance is enhanced through multiple systems designed to maintain control and stability in varying conditions. The Anti-lock Brake System (ABS) prevents wheel lock-up during straight-line braking. Electronic Linked Braking (ELB) distributes brake force between the front and rear wheels when the front brake lever is engaged and, in some cases, when the rear brake pedal is pressed, improving balance during deceleration. The floating design brake rotors ensure consistent friction and temperature management, which is important during prolonged or repeated braking events.
Advanced Rider Modes and Performance Adjustments
The 2025 Harley-Davidson® CVO™ Road Glide® ST includes eight selectable ride modes that modify throttle response, traction control, and suspension behavior. Track and Track+ modes are configured for high-performance riding in closed-course environments, allowing the motorcycle’s systems to deliver maximum output. Other modes provide settings suitable for various conditions, ensuring predictable handling and acceleration across a wide range of riding scenarios. Adjustments can be made via the central display interface, allowing rapid configuration changes without halting the ride.
Integrated Digital Display and Operating System
The 12.3-inch TFT display with Skyline™ OS serves as the main interface for performance data, ride mode selection, navigation, and audio control. Navigation includes traffic and weather overlays for route planning. The Rockford Fosgate® Stage II audio system can be managed through the display, as can all rider safety enhancements. The system’s clear graphics and responsive touchscreen functionality ensure that essential information and adjustments are accessible with minimal distraction.
Traction and Stability Systems
The Traction Control System (TCS) is engineered to prevent the rear wheel from excessive spin during acceleration. The Drag-Torque Slip Control System (DSCS) reduces the risk of rear wheel lock during abrupt deceleration or rapid downshifting, particularly on low-traction surfaces. Vehicle Hold Control (VHC) assists in holding the motorcycle stationary on inclines until the rider initiates forward motion. The Tire Pressure Monitoring System (TPMS) alerts the rider to deviations from optimal pressure levels, which is important for both performance and tire longevity.
Cornering-Enhanced Control Features
Cornering Rider Safety Enhancements integrate lean angle and lateral acceleration data into the operation of ABS, traction control, and slip control systems. Cornering ABS (C-ABS) modulates brake pressure when the motorcycle is leaned over, maintaining grip without reducing control. Cornering Electronic Linked Braking (C-ELB) adjusts brake force distribution based on lean angle, supporting the rider’s intended path through turns. Cornering Traction Control (C-TCS) prevents excessive wheel spin while cornering, while Cornering Drag-Torque Slip Control (C-DSCS) helps maintain stability during aggressive downshifts in turns. Together, these systems provide a consistent balance of control and performance during complex riding maneuvers.
Ergonomic and Functional Design
The seat height, laden, is 26.7 inches, offering accessibility for a range of riders while maintaining cornering clearance. Mini floorboards are positioned to provide support without limiting lean angles. The fairing is shaped to manage airflow and reduce wind buffeting at speed, aiding in rider comfort without impacting handling. Weight distribution and reduced mass from forged carbon fiber and cast aluminum components contribute to precise handling characteristics.
