The 2025 Harley-Davidson® CVO™ Road Glide® ST is a limited-production motorcycle designed with direct influence from MotoAmerica® King of the Baggers™ competition. It introduces lightweight materials, advanced rider assistance systems, and the most powerful engine ever installed in a Harley-Davidson® production model. Its engineering integrates performance, control, and technology into a streamlined package that emphasizes functionality without excess.
Milwaukee-Eight® 121 High Output V-Twin
The motorcycle is powered by the Milwaukee-Eight® 121 High Output V-Twin engine, producing 127 horsepower and 145 foot-pounds of torque. It incorporates a high-performance camshaft and a Heavy Breather intake system to increase airflow and enhance efficiency across the RPM range. The rev limit has been raised to 5,900 rpm, extending usable power during acceleration and sustained highway speeds.
Fuel economy is rated at 44 miles per gallon, balancing output with range for extended riding. Titanium mufflers contribute to reduced overall weight and increased exhaust flow. They also provide a durable, heat-resistant solution with a tuned exhaust rumble that remains consistent under load. This engine represents the strongest factory-installed configuration of Harley-Davidson® to date.
Suspension Systems and Handling Design
Handling precision is achieved with fully adjustable suspension components engineered for control and stability. At the front, SHOWA® 47 mm inverted forks deliver 4.6 inches of travel. Riders can adjust compression, rebound, and preload to match road conditions or individual preference. At the rear, dual outboard SHOWA® remote reservoir shocks are positioned between the saddlebags and rear fender. These shocks provide three inches of travel and separate oil and gas chambers to maintain performance under continuous demand.
The use of cast aluminum wheels reduces unsprung weight and improves handling response. Dual floating brake rotors enhance braking consistency by dissipating heat more efficiently than traditional designs. Brembo® brakes are integrated to provide the stopping force required for a machine of this capability. Together, these features establish a suspension and braking platform designed for stability during aggressive riding and composure during longer-distance travel.
Lightweight Construction and Functional Design
The 2025 Harley-Davidson® CVO™ Road Glide® ST applies weight-saving measures across its construction. Forged carbon fiber is used for the front fender, reducing mass and providing structural strength. The solo seat is shaped for lower back support under heavy acceleration and is narrow enough to support body control during cornering. Mini-boards are fitted to offer stability for the rider’s feet without limiting lean angle.
Premium paint finishes are paired with Screamin' Eagle® graphics that flow from the sides of the fairing into the fuel tank. Accents in Performance Red highlight the powertrain. Tall risers and moto bars allow adjustment of riding ergonomics while supporting rider control in varied conditions. A Flat-Out bar engine guard is designed to protect the paintwork and critical components during low-speed tip-overs while minimizing unnecessary bulk.
Technology Integration and Display Systems
The motorcycle incorporates a 12.3-inch TFT display powered by Skyline™ OS. This large-format screen consolidates critical information such as gauges, navigation with weather and traffic overlays, and access to ride modes. The interface is designed for clear visibility in multiple light conditions and offers intuitive control of rider assistance systems.
The display integrates the Rockford Fosgate® Stage II audio system, providing entertainment control without external devices. Eight ride modes are available, each tuned for different performance requirements. Track and Track+ modes unlock race-level responsiveness reserved for closed-course use. These electronically controlled modes allow riders to tailor throttle response, suspension behavior, and traction intervention to match conditions on demand.
Electronic Rider Safety Systems
Rider Safety Enhancements are standard on the 2025 Harley-Davidson® CVO™ Road Glide® ST, combining multiple technologies that operate during acceleration, braking, and deceleration. Anti-lock braking prevents wheel lock under sudden braking, maintaining steering input during urgent stops. Electronic Linked Braking distributes braking effort between the front and rear wheels, reducing stopping distances and optimizing stability during higher-speed deceleration.
Traction Control monitors wheel spin to prevent loss of grip under acceleration. Drag-Torque Slip Control reduces rear-wheel slip caused by abrupt downshifts or throttle roll-off, particularly on wet or uneven surfaces. Vehicle Hold Control maintains brake pressure after a stop until the throttle is applied, simplifying starts on inclines or ramps.
A Tire Pressure Monitoring System displays alerts for low or high tire pressure, protecting performance consistency and tire life. Cornering-enhanced variations of ABS, Linked Braking, Traction Control, and Drag-Torque Slip Control are included. These systems factor in lean angle to maintain stability during braking or throttle changes while turning. Together, these electronic systems create a controlled and predictable riding environment.
Performance-Oriented Exhaust and Aerodynamics
The use of titanium mufflers demonstrates a balance between lightweight materials and durability. These mufflers enhance exhaust flow while delivering a deep, tuned rumble signature that reflects the motorcycle’s performance focus. Reduced weight in the exhaust system contributes to improved balance and handling responsiveness.
Aerodynamic improvements are evident in the streamlined bodywork, with a fairing designed for both wind deflection and reduced drag. The integration of lightweight components across the design provides a responsive feel while preserving durability.
Ergonomics and Rider Comfort
The 2025 Harley-Davidson® CVO™ Road Glide® ST is configured for performance riding without neglecting rider support. The solo seat offers a stable position during acceleration while also maintaining comfort during longer sessions. Mini-boards allow flexibility in foot positioning, preventing fatigue while supporting cornering clearance. Adjustable risers and moto bars provide options for rider-specific ergonomics, ensuring control is not compromised during high-speed maneuvers.
By combining comfort-focused features with performance geometry, the motorcycle maintains usability during extended riding while retaining its competition-inspired foundation.
