The 2025 Harley-Davidson® Low Rider® ST combines traditional styling cues with contemporary engineering focused on performance and rider control. This model integrates a robust Milwaukee-Eight® 117 High Output V-twin engine, a refined aerodynamic fairing, and advanced electronic systems designed to optimize handling, safety, and rider feedback.
Commanding Power from the Milwaukee-Eight® 117 Engine
Performance in the 2025 Harley-Davidson® Low Rider® ST is driven by the Milwaukee-Eight® 117 High Output engine, rated at 114 horsepower and 128 lb-ft of torque. Designed for stronger delivery in the mid and upper rev range, this engine benefits from a revised redline set at 5,900 rpm. That additional headroom supports extended acceleration under the throttle without compromising control.
The Heavy Breather intake system includes a forward-facing air intake to maximize airflow and optimize volumetric efficiency. This setup is engineered to increase charging efficiency and torque output. The redesigned two-into-one exhaust contributes not only to performance through efficient gas flow but also enhances the bike’s balance and storage capacity by allowing symmetrical saddlebag placement.
Aerodynamic Precision Meets Heritage-Inspired Design
The 2025 Harley-Davidson® Low Rider® ST features a frame-mounted fairing inspired by the classic FXRT style, engineered using computational fluid dynamics to improve airflow around the motorcycle. This fairing is lightweight and intended to reduce aerodynamic drag while improving rider comfort at higher speeds. The aerodynamic profile assists in maintaining stability and reducing wind buffeting during extended rides.
Lighting components include a 146mm LED headlight and redesigned LED taillight and turn signals. These updates provide improved illumination and visibility for the rider. The motorcycle's exterior finishes are available in various premium paint options paired with retro-inspired graphics. Harley-Davidson® maintains a visual link to its heritage while utilizing modern materials and techniques for durability.
Suspension and Braking Engineered for Control
The 2025 Harley-Davidson® Low Rider® ST utilizes a 43mm inverted front fork designed for precise handling and improved feedback on uneven surfaces. The rear suspension employs a tall monoshock, providing increased cornering clearance and enhanced shock absorption. This setup is calibrated to support aggressive riding styles, enabling the motorcycle to maintain stability through tight turns and rapid directional changes.
Braking performance is handled by dual 300mm front disc brakes, which deliver consistent stopping power. Paired with high-performance Michelin® Scorcher® 31 tires, the braking system supports confident deceleration and effective traction on a variety of road surfaces.
Rider-Centric Technology and Control Interface
The model incorporates an upgraded hand control layout with integrated ride mode selection, a repositioned flash-to-pass switch, and an adjustable brake lever to accommodate rider preferences. Ride modes allow adjustment of the bike’s throttle response, traction control, and ABS settings, optimizing performance for different riding environments.
Instrumentation combines a traditional analog speedometer with a four-inch multi-function digital display. This display provides real-time information such as tire pressure monitoring system data, gear position, and active ride mode, enhancing rider awareness. Additionally, the inclusion of a USB-C charging port supports device connectivity for navigation and communication purposes during rides.
Integrated Safety Systems Designed for Stability
The 2025 Harley-Davidson® Low Rider® ST is equipped with the Harley-Davidson® Rider Safety Enhancements suite, which provides multiple layers of electronic assistance to maintain stability and control. The Anti-lock Brake System (ABS) helps prevent wheel lockup during sudden braking, allowing for controlled deceleration. The Traction Control System (TCS) reduces rear wheel spin during acceleration, particularly useful on low-grip surfaces.
The Drag-Torque Slip Control System (DSCS) intervenes to prevent rear wheel lockup caused by abrupt downshifts or rapid throttle release, especially on slippery roads. Enhanced cornering variants of these systems (Cornering ABS, Cornering TCS, and Cornering DSCS) adjust their intervention based on lean angle, improving control and safety during cornering maneuvers.
A tire pressure monitoring system continuously tracks air pressure in both tires and alerts the rider to any deviations from the recommended range. Maintaining proper tire pressure is critical for handling, safety, and tire wear.
Practical Storage and Customizable Styling
The 2025 Harley-Davidson® Low Rider® ST offers lockable saddlebags providing approximately two cubic feet of storage, facilitating practical use for longer rides or touring. The solo seat is designed to provide a secure and stable position, particularly during rapid acceleration and cornering, with a seat height of 27 inches when loaded.
Styling options include black and chrome trim packages, with color choices ranging from Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, Midnight Firestorm, and Blue Burst.
