The 2025 Harley-Davidson® CVO™ Road Glide® ST presents a specialized motorcycle built around track-level performance components adapted for street use. This model draws direct influence from the MotoAmerica® King of the Baggers™ racing series. Its design incorporates lightweight carbon-fiber elements, advanced suspension technology, and one of the most powerful engines in the production of the Harley-Davidson® lineup. The combination of these technical attributes results in a motorcycle engineered to deliver both precision handling and robust power output.
Engine and Powertrain Specifications
The engine installed in the 2025 Harley-Davidson® CVO™ Road Glide® ST is the Milwaukee-Eight® 121 High Output V-twin. It delivers 127 horsepower and 145 foot-pounds of torque, making it the strongest factory-installed engine available in a Harley-Davidson® production motorcycle to date. The engine features a high-performance camshaft and a Heavy Breather intake system that enhances airflow. The engine’s redline has been extended to 5,900 rpm, allowing for a broader usable power band during aggressive riding.
The exhaust system is equipped with titanium mufflers that reduce weight while improving exhaust flow, contributing to engine efficiency and producing a pronounced exhaust rumble. The combination of the Milwaukee-Eight® 121 HO engine and titanium mufflers provides the 2025 Harley-Davidson® CVO™ Road Glide® ST with substantial acceleration and responsiveness across a wide range of speeds.
Structural and Design Components
The design of the 2025 Harley-Davidson® CVO™ Road Glide® ST incorporates lightweight materials typically found in racing motorcycles to improve handling and reduce overall mass. One key feature is the forged carbon fiber front fender, which replaces a traditional steel fender to cut weight while maintaining durability and providing a high-quality finish.
The motorcycle rides on cast aluminum wheels, chosen for their ability to reduce unsprung weight. Reduced unsprung weight improves suspension performance and handling responsiveness. The wheels are paired with dual floating brake rotors, which improve heat dissipation and braking consistency during demanding use.
A solo seat is integrated into the design, engineered with a steep back section to support the lower back during acceleration and maintain rider stability when cornering. The seat is lightweight but designed to provide adequate comfort and control.
Ergonomics are adjustable through tall risers and moto-bars, allowing riders to customize handlebar height and position. A minimalistic Flat-Out engine guard is included to protect the limited-edition paint and provide some protection during low-speed tips without detracting from the bike’s sleek profile.
Suspension and Handling Systems
The suspension system of the 2025 Harley-Davidson® CVO™ Road Glide® ST features fully adjustable front and rear components for precision tuning. The front suspension uses 47 mm inverted SHOWA® forks with 4.6 inches of travel. These forks can be adjusted for compression, rebound, and preload, enabling riders to tailor the ride quality according to preference or road conditions.
At the rear, dual outboard SHOWA® Remote Reservoir shocks provide three inches of travel. These shocks maintain consistent damping by separating oil and gas, preventing foaming during prolonged or aggressive use. The remote reservoirs allow for improved heat dissipation and performance stability.
This suspension package supports the bike’s dynamic handling, providing both comfort and control across various road surfaces. The reduced unsprung weight from the wheels and high-quality suspension components contribute to a balanced and responsive ride experience.
Mini floorboards replace larger traditional floorboards to offer sufficient foot support without limiting lean angle. This design enhances rider maneuverability during turns.
Technology Integration and Display Interface
A 12.3-inch TFT touchscreen display featuring the Skyline™ operating system provides the rider with real-time access to performance data, navigation, and audio controls. The display includes gauges, customizable ride modes, and overlays for traffic and weather conditions. The Rockford Fosgate® Stage II audio system is integrated and controlled through this interface.
Eight ride modes are available, allowing for on-the-fly adjustments to engine response, traction control, and ABS settings. Among these modes are Track and Track+ settings. which unlock performance levels suitable for closed-course or race use. These modes provide options for more aggressive power delivery and adjusted electronic controls.
The combination of the TFT display and multiple ride modes offers riders an adaptable and customizable riding experience while providing clear access to essential information.
Rider Safety Enhancements and Brake Systems
The 2025 Harley-Davidson® CVO™ Road Glide® ST incorporates Rider Safety Enhancements, a suite of electronic systems from Harley-Davidson® that assist with traction, braking, and stability. The system includes Cornering ABS, which adjusts braking pressure based on lean angle to help maintain control when braking through turns.
Electronic Linked Braking (ELB) distributes braking force between the front and rear wheels when the rider applies either brake control, improving overall braking effectiveness. Cornering Enhanced Electronic Linked Braking (C-ELB) further adjusts this system based on motorcycle lean angle, ensuring stability during cornering maneuvers.
Traction Control System (TCS) helps prevent rear wheel spin during acceleration, adapting its response in cornering situations through Cornering Traction Control (C-TCS). The Drag-Torque Slip Control System (DSCS) mitigates rear wheel slip caused by sudden downshifts or throttle reduction, with the cornering variant (C-DSCS) adjusting for bike lean or lateral acceleration.
Vehicle Hold Control (VHC) locks the brakes automatically when the rider releases them at a stop, aiding hill starts or stationary stops. It maintains brake pressure until the rider initiates movement, reducing the chance of rollback.
The braking hardware itself includes Brembo® calipers and dual floating rotors on the front wheels. These components are designed for consistent, powerful stopping capability and improved heat management during repeated or high-intensity braking.
The Tire Pressure Monitoring System (TPMS) provides real-time alerts regarding tire pressure, supporting optimal tire performance and safety.
Integrated Functional Features and Rider Ergonomics
The bike maintains a low seat height of 26.7 inches when laden, which supports rider stability during stops and low-speed maneuvers. Mini floorboards provide secure and ergonomic foot positioning without restricting lean angles during cornering.
The combination of lightweight materials, advanced suspension, and ergonomic design enhances the motorcycle’s agility and handling precision. These features ensure that the rider maintains control and comfort across a range of riding conditions.
