The 2025 Harley-Davidson® Low Rider® ST is a performance-oriented motorcycle that blends traditional Harley-Davidson® design with contemporary mechanical and electronic engineering. Its structure, powertrain, and electronic systems are configured to improve handling, efficiency, and long-distance capability. This bike combines proven Harley-Davidson® craftsmanship with modern updates across its frame, suspension, safety systems, and digital integration.
Milwaukee-Eight® 117 High Output Engine
The 2025 Harley-Davidson® Low Rider® ST is powered by the Milwaukee-Eight® 117 High Output V-twin engine. This configuration produces 128 ft-lb of torque and 114 horsepower. The design incorporates refined airflow, enhanced combustion efficiency, and improved cooling performance for higher sustained power delivery. The redline has been increased from 5,600 rpm to 5,900 rpm, allowing longer operation in higher rev ranges.
Fuel economy is rated at 47 miles per gallon, giving the model balance between performance and endurance. The engine’s operation remains smooth under variable conditions due to improved valve timing and airflow tuning. A forward-facing Heavy Breather intake enhances air delivery and supports better torque performance at mid and upper ranges. The two-into-one exhaust system aligns with the engine’s airflow design, improving exhaust velocity and producing an even power curve. The exhaust layout also maintains symmetry across the saddlebags and contributes to overall balance and acoustic refinement.
Precision Handling and Suspension
The motorcycle’s suspension system is engineered for precise handling and control. A tall rear monoshock raises the rear section and increases cornering clearance. This setup enhances lean angles and cornering stability during aggressive riding. The 43 mm inverted front fork provides front-end stiffness and minimizes flex during braking and directional changes.
The frame geometry contributes to predictable handling and stability during extended touring. Dual front brake discs offer consistent stopping power, supported by a high-efficiency hydraulic system that improves braking response under high loads. Combined with Michelin® Scorcher® 31 tires, the chassis maintains consistent grip and predictable feedback in both wet and dry conditions. The braking and suspension systems are tuned for stability, control, and durability across various road environments.
Frame-Mounted Fairing and Aerodynamics
The 2025 Harley-Davidson® Low Rider® ST includes a frame-mounted fairing developed using computational fluid dynamics. This method improves aerodynamic efficiency and reduces rider fatigue at sustained speeds. The fairing design draws influence from the classic FXRT-style aesthetic, modernized for stability and reduced drag.
The fairing’s positioning helps distribute airflow evenly across the rider’s position, improving comfort during extended riding. The 146 mm LED headlamp is integrated directly into the fairing, delivering higher brightness and improved visibility. The fairing construction maintains a low profile while reducing wind buffeting and vibration. These aerodynamic refinements support both touring and performance applications.
Refined Design and Construction
The 2025 Harley-Davidson® Low Rider® ST merges classic Harley-Davidson® styling with functional updates. It features a single-rider configuration with a slim solo seat that stabilizes the rider during acceleration and cornering. The body includes color-matched components, a redesigned taillight assembly, and updated LED turn signals.
Paint options vary by trim selection. The black trim variant includes Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, and Midnight Firestorm. The chrome trim version includes Billiard Gray, Vivid Black, and Blue Burst. Each version features retro-inspired tank graphics that connect to the design heritage of Harley-Davidson®.
Lockable saddlebags with a total of 2 cubic feet of storage are integrated seamlessly into the body. These saddlebags are shaped to maintain aerodynamic flow and provide secure space for touring use. The bike’s design reflects a balance of vintage influence and modern mechanical precision, ensuring that every component contributes to the motorcycle’s overall performance efficiency.
Rider Interface and Electronic Systems
The 2025 Harley-Davidson® Low Rider® ST features an updated rider information display designed for clarity and control. A 4-inch display combines an analog speedometer with a digital readout that presents ride mode settings, tire pressure information, gear position, and trip data. The system is compact and mounted for visibility while minimizing distraction.
Three ride modes are available and can be selected through the left-hand control system. Each mode adjusts power delivery, traction sensitivity, and throttle response based on rider preference and road surface. The controls have been redesigned for easier operation, including a repositioned flash-to-pass switch and an adjustable brake lever for better reach customization.
The display also supports a USB-C charging port to maintain power for navigation or connected Bluetooth® devices. These electronic systems are integrated with the motorcycle’s overall electrical architecture to ensure consistent function during extended rides and high-load conditions.
Advanced Safety and Stability Technologies
The 2025 Harley-Davidson® Low Rider® ST incorporates the Harley-Davidson® Rider Safety Enhancements suite, which provides assistance during acceleration, braking, and cornering. The systems use sensors to monitor traction and adjust brake pressure or torque delivery when necessary.
The Anti-lock Brake System prevents wheel lock during hard braking to maintain stability and control. The Traction Control System manages rear wheel spin under rapid acceleration. The Drag-Torque Slip Control System moderates rear wheel slip during abrupt throttle reductions or downshifts, maintaining grip on wet or low-friction surfaces.
The Tire Pressure Monitoring System displays pressure readings directly on the instrument panel, alerting the rider to low or high tire pressure that could affect handling or tire life. Cornering-enhanced versions of these systems provide adaptive functionality based on lean angle and lateral acceleration. The Cornering Enhanced Anti-lock Brake System adjusts braking force during turns, while the Cornering Enhanced Traction Control System maintains grip under acceleration. The Cornering Drag-Torque Slip Control System stabilizes deceleration by adjusting power delivery during cornering transitions. These systems work together to maintain balanced performance and predictable handling.
Structure and Ergonomics for Touring
The motorcycle’s structure supports both performance and touring applications. The ergonomically shaped solo seat provides a secure position for extended rides, and the frame geometry supports a natural riding posture that reduces fatigue. Suspension components are tuned for long-distance stability while maintaining responsive handling characteristics.
Storage integration allows the rider to carry essentials without compromising aerodynamics or balance. The fuel tank and saddlebag placement maintain a centered mass, improving control at low speeds and maintaining stability during highway travel. Every design aspect supports consistent performance during extended operation without unnecessary complexity.
Powertrain Efficiency and System Coordination
Engine components and driveline geometry are optimized to coordinate torque output with chassis balance. The 6-speed transmission delivers consistent gear engagement and minimizes vibration. The final drive ratio has been selected to support both strong acceleration and efficient highway cruising.
The cooling and lubrication systems maintain stable engine temperatures even under sustained load. Combined with the air intake and exhaust tuning, these systems contribute to the motorcycle’s efficiency, reliability, and overall refinement. The drivetrain configuration of the 2025 Harley-Davidson® Low Rider® ST ensures responsive output while maintaining operational smoothness through all speed ranges.
Lighting and Visibility
Lighting performance is enhanced through a fully integrated LED system. The headlamp produces a bright, focused beam that improves road visibility at night and in low-light environments. The LED taillight and turn signals improve signaling recognition for surrounding traffic. This system also reduces power consumption while extending service life.
The lighting assembly is positioned for optimal distribution and conforms to the aerodynamic flow of the fairing and rear structure. These updates contribute to overall visibility and safety while maintaining the motorcycle’s signature Harley-Davidson® appearance.
