The 2025 Harley-Davidson® CVO™ Road Glide® ST introduces a motorcycle engineered with performance components, precision-focused ergonomics, and advanced technology drawn directly from competition standards. Lightweight construction, the Milwaukee-Eight® 121 High Output engine, and rider-focused electronics create a machine designed for those who require performance and technical refinement.
Engine Configuration and Output
The 2025 Harley-Davidson® CVO™ Road Glide® ST is powered by the Milwaukee-Eight® 121 High Output V-Twin engine, which produces 127 horsepower and 145 ft-lb of torque. It is the most powerful production engine Harley-Davidson® has ever factory-installed, designed with a high-performance camshaft, a Heavy Breather Intake system, and an increased rev limit of 5,900 rpm.
Suspension Architecture and Handling
SHOWA® 47mm inverted front forks provide 4.6 inches of travel and are fully adjustable for preload, compression, and rebound. The rear suspension uses dual outboard SHOWA® Remote Reservoir shocks with three inches of travel. These shocks are mounted between the saddlebags and the rear fender, ensuring consistent oil and gas separation for performance stability under high-stress conditions.
Frame and Weight Reduction Measures
The design of the motorcycle incorporates lightweight materials to improve responsiveness and efficiency. A forged carbon fiber front fender replaces a conventional steel fender, cutting weight while maintaining rigidity. Cast aluminum wheels further reduce unsprung mass, increasing handling precision and heat dissipation through dual floating brake rotors. The solo seat is sculpted to provide lumbar support and security under acceleration or cornering forces. Moto-style handlebars paired with tall risers allow riders to adjust ergonomics to their preference, enhancing control while maintaining the visibility of the premium paint design that integrates Screamin' Eagle® graphics and Performance Red accents.
Technology Interface and Rider Adjustability
The 2025 Harley-Davidson® CVO™ Road Glide® ST integrates Skyline™ OS on a 12.3-inch TFT display. This touchscreen system manages navigation with traffic and weather overlays, ride modes, and the Rockford Fosgate® Stage II audio package. Eight ride modes are included, ranging from standard touring adjustments to Track and Track+ settings that are specifically designed for closed-course environments.
Safety Systems and Rider Confidence
The motorcycle includes a full suite of Rider Safety Enhancements. The standard Anti-lock Brake System is paired with Cornering Enhanced ABS, which adjusts braking force depending on lean angle to maintain control during turns. Electronic Linked Braking distributes force between the front and rear wheels, while Cornering Enhanced ELB modifies distribution dynamically during lean. Traction Control ensures stable power delivery, with Cornering Enhanced TCS preventing excessive spin under lean. The Drag-Torque Slip Control System helps prevent wheel lock during downshifts or throttle reductions, while Cornering Enhanced DSCS refines this function while the motorcycle is leaned over. Vehicle Hold Control is also included, preventing unintended rollback on inclines by maintaining brake pressure until throttle input is applied. The Tire Pressure Monitoring System provides alerts for pressure deviations, supporting consistent handling and extended tire life.
Exhaust and Acoustic Performance
Titanium mufflers reduce system weight while ensuring efficient gas flow and thermal resistance. They are engineered to deliver an exhaust tone that is both distinct and muscular without excessive resonance. This setup complements the Milwaukee-Eight® 121 High Output engine by supporting improved mid-range performance and maintaining strength across extended use cycles.
Rider Ergonomics and Functional Comfort
The riding position is designed for stability and control. The solo seat provides firm support during acceleration and cornering, minimizing fatigue and improving rider security. Mini floorboards, known as mini-boards, are included to offer sufficient foot support without compromising lean angle. Combined with tall risers and moto-style bars, the configuration delivers a balanced ergonomic arrangement suited for extended riding or aggressive handling.
Fuel Efficiency and Dimensions
The motorcycle achieves a fuel economy of 44 miles per gallon. Laden seat height is measured at 26.7 inches, ensuring accessibility without compromising ground clearance. Trim options include a black finish, with Mercury Silver, Rally Red, and Hot Lap paint schemes available.
Design Detailing and Aesthetic Integration
The motorcycle’s Screamin' Eagle® graphics flow across the fairing and fuel tank to create a unified look. Performance Red highlights applied to the powertrain emphasize its mechanical focus. Forged carbon fiber surfaces and cast aluminum wheels maintain a premium appearance while serving functional performance purposes.
