The 2025 Harley-Davidson® CVO™ Road Glide® ST is a performance touring motorcycle that draws direct influence from competitive racing environments. It is designed around a high-output V-twin engine, precision-tuned chassis, and integrated electronics. The overall platform targets riders who expect rapid throttle response, controlled handling, and usable rider aids. Each component of the motorcycle has been selected for function, with reduced weight and improved control as the primary goals.
At the center of the platform is the Milwaukee-Eight® 121 High Output engine. This air- and oil-cooled V-twin produces 127 horsepower and 145 foot-pounds of torque. The engine includes a high-performance camshaft and a Heavy Breather intake system. The rev limit is raised to 5,900 rpm, offering a broader usable range than standard configurations. Power is delivered through a six-speed transmission designed to handle the torque load without sacrificing smoothness or shift accuracy. Engine management systems adjust fueling and spark in real time to maintain stability under rapid throttle transitions. Titanium mufflers reduce mass and improve exhaust flow while retaining a functional sound profile.
The suspension system is fully adjustable. The front setup includes 47-millimeter inverted SHOWA® forks. These provide 4.6 inches of travel and allow riders to control compression, rebound, and preload. The rear section uses SHOWA® Remote Reservoir shocks with three inches of travel. These are positioned outside the fender and saddlebag area to support oil and gas separation under heavy use.
Geometry settings support controlled turn-in and steady mid-corner stability. The design promotes direct rider input without excessive feedback. The frame and subframe are tuned to reduce flex without adding weight. Fork rake and trail settings support higher-speed stability while maintaining responsiveness in slower environments.
The 2025 Harley-Davidson® CVO™ Road Glide® ST uses dual front brake rotors that float independently, which improves heat dissipation under repeated use. Brake modulation is handled by a linked braking system. The front lever can engage rear braking electronically, which assists in balance during aggressive deceleration.
An anti-lock braking system is standard. It modulates hydraulic pressure to prevent wheel lock-up during abrupt stops. Brake feel is consistent at both levers, with tuning that allows for progressive engagement. The system supports lean-angle detection, which adjusts pressure based on lateral input. This helps reduce loss of traction in cornering scenarios.
The front fender is constructed from forged carbon fiber. This material reduces weight over a steel equivalent while increasing rigidity. Cast aluminum wheels also contribute to reduced unsprung mass. Together, these elements improve suspension reaction speed and allow for quicker changes in direction.
Frame-mounted elements such as the Flat-Out bar serve both a protective and structural role. While designed for tip-over protection, they are kept minimal to avoid excess weight. Bodywork features integrated aerodynamics without large surfaces that could generate drag at speed. The frame-mounted fairing improves airflow stability and contributes to reduced buffeting at highway speeds.
The seating arrangement is designed for solo operation. The rider seat has a steep back that provides support during acceleration and cornering. Foot controls are positioned on mini-boards. These provide lateral stability without the space requirements of full-length boards.
Handlebar placement is modified through the use of tall risers and moto-style bars. This layout provides leverage for precise control and reduces fatigue in technical riding. Control switches are within reach and spaced for glove use. The fuel tank and tank panel allow for a close riding posture without pressure on the thighs or knees.
A 12.3-inch TFT display operates on the Skyline™ operating system. This display manages ride data, diagnostics, ride modes, and audio controls. Layout options are customizable. Visual clarity remains consistent in direct sunlight due to screen brightness and anti-glare coatings.
The system provides access to eight ride modes. Each setting adjusts throttle response, engine braking, and traction control levels. Two of these modes, Track and Track+, are tuned for closed-course performance. They provide sharper input response and minimal electronic intervention unless a critical threshold is met.
Navigation features are built into the display. Traffic and weather overlays are included through network connectivity. Audio output is delivered through a Rockford Fosgate® Stage II system, which integrates with the display.
Traction control is active in all ride modes. The system monitors wheel slip and adjusts power delivery to the rear tire. The Cornering Traction Control variant adds lean-angle sensors to refine input further during turns. It reduces torque when excessive slip is detected during both straight-line and leaned-over riding.
The Drag-Torque Slip Control System adjusts clutch and throttle input to prevent rear-wheel lock during abrupt deceleration. This can occur in downshifts or when the throttle is rapidly closed on a wet surface. A cornering-enhanced version monitors lateral forces and modifies behavior based on real-time geometry.
Electronic Linked Braking assists riders by applying pressure to both front and rear brakes, even when only one control is engaged. The system determines balance based on load and speed. A cornering version of this feature further refines the pressure balance depending on lean angle and acceleration values.
Vehicle Hold Control keeps the bike stationary after the brake is released when stopped on an incline or decline. This system disengages once forward motion is resumed.
Tire Pressure Monitoring is standard. The system provides alerts through the central display when air pressure drops below or rises above recommended limits. This prevents performance degradation and supports tire longevity.
