The 2025 Harley-Davidson® CVO™ Road Glide® ST combines competitive motorcycle technology with advanced materials and precision control. Built to bring the performance of MotoAmerica® King of the Baggers™ race machines to public roads, this model focuses on lightweight construction, high-output power, and rider-centric adjustments for a dynamic yet manageable ride.
Milwaukee-Eight® 121 High Output: Engineering Maximum Power and Torque
Power delivery in the 2025 Harley-Davidson® CVO™ Road Glide® ST originates from the Milwaukee-Eight® 121 High Output V-twin engine. This engine sets a new standard as the most powerful factory-installed engine in any Harley-Davidson® production bike, producing 127 horsepower and 145 foot-pounds of torque. It includes a high-performance camshaft that enhances valve timing for optimized airflow and combustion. The Heavy Breather Intake further improves air induction, allowing for a raised redline of 5,900 rpm and extending the engine’s usable power band.
Lightweight titanium mufflers complement the engine by improving exhaust flow and reducing weight, all while delivering the brand’s signature exhaust rumble with increased depth and resonance.
Carbon Fiber and Aluminum: Reducing Weight Without Compromise
The 2025 Harley-Davidson® CVO™ Road Glide® ST incorporates advanced materials inspired by racing technology to lower overall weight and improve handling. The forged carbon fiber front fender replaces the standard steel alternative, cutting unsprung weight and improving front-end responsiveness.
Cast aluminum wheels further reduce unsprung mass compared to traditional wheels, enhancing maneuverability and contributing to quicker steering responses. The dual floating brake rotors are designed for superior heat dissipation, maintaining braking performance during extended or aggressive use.
Suspension Systems Tuned for Precision and Adaptability
Handling refinement is achieved through fully adjustable suspension components. The front suspension consists of SHOWA® 47mm inverted forks with 4.6 inches of travel. These forks provide settings for compression, rebound, and preload, enabling riders to adjust for comfort, stability, and handling feedback according to personal preference and riding conditions.
At the rear, dual outboard SHOWA® Remote Reservoir shocks with three inches of travel maintain consistent damping by separating oil and gas reservoirs. Positioned strategically between the saddlebags and rear fender, these shocks contribute to stable performance during acceleration, braking, and cornering.
Brembo® brakes paired with the dual floating rotors offer strong, consistent stopping power, while mini floorboards provide necessary foot support without limiting the bike’s lean angle or rider mobility.
Advanced Display and Ride Modes for Informed Control
A 12.3-inch TFT touchscreen display operating on Skyline™ OS delivers essential ride data, navigation with traffic and weather overlays, and audio controls. The interface is designed for intuitive use, allowing riders to make adjustments quickly and safely while on the move.
The motorcycle offers eight distinct ride modes, including Track and Track+ modes developed for closed-course conditions. These modes fine-tune throttle response, traction control, and braking sensitivity to match different riding scenarios, from casual cruising to aggressive track use.
Electronic Safety Systems Enhancing Rider Stability
The 2025 Harley-Davidson® CVO™ Road Glide® ST integrates a comprehensive suite of electronic safety aids that work together to maintain traction and stability. Cornering Enhanced Anti-lock Brake System (C-ABS) modulates braking pressure relative to the bike’s lean angle, preventing wheel lock during cornering.
Electronic Linked Braking (ELB) distributes braking force between the front and rear wheels to enhance stability and braking effectiveness. The Traction Control System (TCS) manages rear wheel spin during acceleration to maintain grip on varying road surfaces. Drag-Torque Slip Control System (DSCS) helps control rear wheel slip during abrupt downshifts or throttle release, especially in wet or slippery conditions. Vehicle Hold Control (VHC) secures the bike at a stop to prevent rollback on inclines. The Tire Pressure Monitoring System (TPMS) alerts the rider to deviations in tire pressure, supporting consistent performance and safety.
Ergonomics and Efficiency Engineered for Ride Quality
The seat height of 26.7 inches (laden) balances rider accessibility with the need for ground clearance suited to performance riding. Adjustable risers and handlebars enable ergonomic customization, supporting rider comfort and control over extended periods. Mini floorboards offer stable foot placement while allowing for aggressive lean angles and maneuvering.
Despite its high-performance focus and race-inspired design, the motorcycle achieves an estimated fuel economy of 44 miles per gallon.
