The 2025 Harley-Davidson® CVO™ Road Glide® ST integrates elements derived from professional MotoAmerica® King of the Baggers™ race bikes into a street-legal motorcycle designed for high-performance riding. It combines lightweight construction with powerful mechanical components and advanced electronic systems to produce a machine focused on performance, control, and efficiency. This model features a powerful engine alongside race-inspired materials and suspension technologies tailored for precision handling.
Engine Performance and Mechanical Specifications
The 2025 Harley-Davidson® CVO™ Road Glide® ST is equipped with the Milwaukee-Eight® 121 High Output V-twin engine. This engine produces 127 horsepower and 145 foot-pounds of torque. It features a high-performance camshaft and a Heavy Breather Intake system designed to optimize airflow and combustion efficiency. The engine’s maximum rpm is raised to 5,900, extending the usable power band and allowing for higher performance in a variety of riding conditions.
The exhaust system uses lightweight titanium mufflers which reduce overall weight and increase exhaust flow. These mufflers contribute to a distinctive exhaust rumble that combines depth with clarity. Despite the engine’s high output, fuel economy is rated at 44 miles per gallon, balancing power delivery with efficiency. The bike’s seat height when laden is 26.7 inches, providing a riding position suitable for both control and comfort.
Design and Weight Reduction Strategies
The design of the 2025 Harley-Davidson® CVO™ Road Glide® ST reflects an emphasis on weight reduction and material innovation. Forged carbon fiber is employed for the front fender, replacing traditional steel components. This change reduces unsprung weight and offers a finish consistent with race bike aesthetics. The use of carbon fiber extends to various other components, contributing to the bike’s overall reduced mass without compromising structural integrity.
The wheels are cast aluminum, chosen for their ability to lower unsprung weight, which enhances handling responsiveness and suspension performance. These wheels are matched with dual floating brake rotors, which provide superior heat dissipation compared to standard rotors, maintaining braking effectiveness during extended or aggressive use.
The bike includes P&A tall risers and moto bars, allowing riders to fine-tune handlebar position to match personal ergonomic preferences. Engine guards with a Flat-Out bar design provide protection for the limited-edition paint and help safeguard the bike in the event of a low-speed tip-over. The solo seat is designed with a steep backrest to offer support for the lower back during acceleration and to maintain grip when cornering aggressively.
Premium paint finishes include Mercury Silver, Rally Red, and Hot Lap, each featuring the Screamin' Eagle® graphic that flows from the fairing to the fuel tank and is complemented by red accents on the powertrain components.
Suspension and Handling Technology
The suspension system on the 2025 Harley-Davidson® CVO™ Road Glide® ST consists of fully adjustable components designed to offer precise control. The front suspension uses SHOWA® 47mm inverted forks with 4.6 inches of travel. These forks are adjustable for compression, rebound, and preload, allowing riders to configure the suspension according to individual preferences and road conditions.
The rear suspension features dual outboard SHOWA® Remote Reservoir shocks with 3 inches of travel. These shocks separate the oil and gas chambers to maintain consistent damping performance even under demanding riding conditions, such as aggressive cornering or extended high-speed runs.
The mini floorboards provide foot support that is firm yet compact, allowing for greater lean angles without sacrificing rider stability. The combination of lightweight suspension components, precise adjustability, and reduced unsprung weight contributes to the bike’s agile handling and rider confidence.
Advanced Rider Interface and Electronic Controls
The bike is equipped with a 12.3-inch TFT touchscreen display powered by the Skyline™ OS. This display presents vital information such as speed, engine data, and navigation, while also managing the Rockford Fosgate® Stage II audio system. The interface allows riders to adjust settings quickly, including ride modes and safety features, through an accessible and readable touchscreen.
There are eight selectable ride modes, including Track and Track+ modes. These two track-specific modes unlock performance settings designed for closed-course riding, enabling riders to access the highest level of engine responsiveness, traction control adjustments, and braking configurations. The other ride modes cover a range of street riding scenarios, giving users the flexibility to modify throttle response, suspension settings, and electronic assistance to fit the conditions.
Safety Systems and Rider Aids
The 2025 Harley-Davidson® CVO™ Road Glide® ST incorporates Rider Safety Enhancements, which include multiple advanced electronic control systems to assist riders in maintaining control in challenging situations. Cornering ABS adapts brake pressure based on lean angle to prevent wheel lockup while turning, improving stability and rider control.
Electronic Linked Braking (ELB) applies braking force to both wheels when either front or rear brakes are activated, optimizing braking balance and effectiveness. The system can modify the brake link based on speed or rider input to offer lighter braking or increased power as required.
Traction Control System (TCS) prevents excessive rear wheel spin during acceleration, improving stability on various road surfaces. Drag-Torque Slip Control System (DSCS) reduces rear wheel slip and prevents lockup during sudden downshifts or throttle closure, especially on wet or slippery surfaces. This system adjusts dynamically depending on lean angle and riding conditions.
Vehicle Hold Control (VHC) holds the brakes after a complete stop without requiring the rider to keep the brake lever or pedal engaged, making hill starts smoother and reducing rider effort. Tire Pressure Monitoring System (TPMS) continuously monitors tire air pressure and alerts the rider to abnormal pressure levels, supporting tire longevity and safety.
Ergonomics and Rider Control
The motorcycle’s ergonomic design balances rider comfort with control. The combination of adjustable handlebars, risers, and a solo seat with a pronounced backrest allows the rider to maintain a stable and comfortable posture during both aggressive and casual riding. Mini floorboards deliver solid foot support while allowing for effective lean angles in corners.
The integration of Brembo® brakes complements the bike’s powerful engine, providing reliable and consistent stopping power with precise feedback to the rider. The balance between lightweight components, suspension tuning, and brake performance enhances handling, especially during spirited riding or technical maneuvers.
