The 2025 Harley-Davidson® Low Rider® ST represents a clear focus on combining established design elements with modern engineering advances. This sport-touring motorcycle integrates performance, rider safety, and practical technology into a configuration suited for both aggressive riding and long-distance travel. The model’s design draws directly from the West Coast custom lineage of Harley-Davidson®, updated with contemporary components and systems. The result is a machine that balances raw engine power with aerodynamic refinement and advanced rider assistance.
Engine Performance: The Milwaukee-Eight® 117 High Output Powertrain
At the core of the 2025 Harley-Davidson® Low Rider® ST is the Milwaukee-Eight® 117 High Output engine, a 117 cubic inch V-twin powerplant engineered for increased torque and horsepower output. The engine delivers 114 horsepower and generates 128 foot-pounds of torque, figures that place it among the more powerful offerings in the lineup of Harley-Davidson®. The redline is set at 5,900 revolutions per minute, an increase over previous models.
The Heavy Breather intake system is designed for forward-facing airflow, improving volumetric efficiency and enhancing the engine’s charging process. Complementing the engine is a redesigned two-into-one exhaust system, which has been engineered to improve exhaust scavenging and flow dynamics. The exhaust layout also supports symmetrical saddlebag placement and maintains a clean overall appearance, preparing the bike for potential aftermarket customization.
Fuel efficiency stands at approximately 47 miles per gallon. The fuel system and engine management software have been calibrated to balance performance demands with reasonable consumption.
Aerodynamics and Design: Combining Heritage with Functional Engineering
The fairing takes design cues from the classic FXRT Sport Glide® but incorporates modern aerodynamic improvements. Its frame-mounted fairing is lightweight and has been shaped using computational fluid dynamics analysis. The aerodynamic refinement supports rider comfort by managing airflow around the helmet and upper body, reducing buffeting and wind noise.
Lighting components have been updated to use full LED technology. The primary headlamp measures 5.75 inches in diameter and provides a focused beam pattern optimized for nighttime visibility. LED turn signals and a redesigned taillight improve signal clarity and durability compared to traditional bulb systems. The bike’s color options include both Black and Chrome trims with a range of finishes such as Billiard Gray, Vivid Black, Brilliant Red, and Iron Horse Metallic. The tank graphics are inspired by heritage designs and are applied using premium paint processes.
The seating arrangement consists of a slim solo seat that is engineered for rider stability during acceleration and cornering.
Suspension and Handling: Focused on Control and Cornering Ability
The suspension system is specifically tuned to enhance cornering clearance and improve handling dynamics. At the front, the bike uses a 43mm inverted fork, which increases rigidity and reduces flex during aggressive riding. The rear suspension features a tall monoshock unit that raises the bike’s rear height, providing increased lean angle capacity.
The braking system includes dual 300mm front disc brakes, designed to deliver strong stopping power and consistent performance under heavy use. The system works in conjunction with advanced cornering anti-lock brake system, which adjusts braking force based on the lean angle. Michelin® Scorcher® 31 tires are specified for their balance of grip, longevity, and road feedback, further supporting confident handling characteristics.
Rider Technology and Safety: Integrated Systems for Control and Awareness
The 2025 Harley-Davidson® Low Rider® ST features a four-inch multi-function instrument display situated beneath an analog speedometer. This display consolidates essential data including gear position, tire pressure, and ride mode selection. The interface is designed to be clear and accessible, allowing riders to monitor and adjust settings without distraction.
Three distinct ride modes can be selected via the left-hand controls. These modes alter throttle mapping, traction control sensitivity, and other powertrain parameters to suit different riding conditions and preferences. The hand controls also feature an adjustable brake lever and a repositioned flash-to-pass switch for ergonomic operation.
Safety systems integrated into the bike include multiple layers of rider assistance. The Anti-lock Brake System prevents wheel lockup during hard braking. Traction Control System manages rear wheel slip during acceleration. Drag-Torque Slip Control reduces rear wheel lockup and slip during rapid deceleration and downshifting, particularly on wet or low-traction surfaces. The cornering versions of these systems, Cornering Enhanced ABS, Traction Control, and Drag-Torque Slip Control, adjust their operation based on the motorcycle’s lean angle, enabling safer braking and traction management in curves.
The Tire Pressure Monitoring System continuously monitors air pressure in both tires and alerts the rider via the instrument display if pressures fall outside optimal ranges.
Connectivity and Practical Features: Designed for Modern Riding Demands
To accommodate modern rider needs, the 2025 Harley-Davidson® Low Rider® ST incorporates a USB-C charging port for powering devices such as GPS units, smartphones, and Bluetooth® communication systems.
Storage capacity is enhanced by the inclusion of two lockable saddlebags, offering a combined volume of two cubic feet. These hard cases provide secure space for carrying essentials and are designed to maintain the bike’s aerodynamic and visual lines without excessive bulk.
