The 2025 Harley-Davidson® Low Rider® ST represents a modern interpretation of sport-touring design with advanced engineering and precise technical specifications. Built with a performance-oriented approach, this motorcycle integrates a new generation of power delivery, aerodynamic refinement, updated technology, and safety enhancements. The model combines proven V-Twin engineering with updates in suspension, control systems, and rider interface, making it a distinctive option for riders who want detailed functionality from a modern Harley-Davidson® platform.
Powertrain Engineering and Performance Output
The Milwaukee-Eight® 117 High Output V-Twin engine defines the motorcycle’s performance character. The engine produces 114 horsepower and 128 foot-pounds of torque, supplying strong acceleration across the rev range. Enhancements to this engine extend its redline from 5,600 revolutions per minute to 5,900 revolutions per minute.
The Heavy Breather intake system contributes to charging efficiency through a forward-facing design that maximizes airflow. This system optimizes intake tuning length, which improves torque delivery across operating conditions. A two-into-one exhaust configuration complements the intake system by refining output balance, maintaining symmetry around the saddlebags, and providing a foundation for customization.
The combined effect of these updates is an engine that supports longer acceleration periods, improved top-end stability, and consistent power delivery. The balance of horsepower and torque is matched by a fuel economy rating of 47 miles per gallon, aligning output with efficiency for sustained touring performance.
Suspension, Braking, and Cornering Stability
Handling performance is supported by a suspension system engineered for both comfort and cornering precision. At the rear, a tall monoshock raises the motorcycle’s stance while improving cornering clearance. This configuration enhances lean angles and gives the rider additional control in aggressive situations. The front suspension features a 43-millimeter inverted fork calibrated for stability, front-end feedback, and reduced flex under load.
Braking performance comes from a dual front disc system equipped with 300-millimeter rotors. This setup provides consistent stopping force, while distribution across both discs reduces fade and increases reliability. Michelin® Scorcher® 31 tires complement the braking and suspension systems with dependable grip across surfaces, allowing riders to maintain control during high-performance maneuvers and extended touring rides.
Aerodynamic Refinements and Structural Design
The design of the 2025 Harley-Davidson® Low Rider® ST reflects a combination of retro styling cues with modern aerodynamic development. A frame-mounted fairing, inspired by the FXRT style, serves as a defining structural component. Developed with computational fluid dynamics, the fairing minimizes drag and improves wind deflection. This reduces turbulence for the rider, contributing to comfort during extended highway travel.
Lighting integration reflects functional improvement through LED systems. A 5.75-inch LED headlamp provides strong forward visibility, while redesigned taillights and LED turn signals enhance signaling efficiency.
Paint finishes include premium applications with retro-inspired graphics that connect the model’s design heritage to modern visual standards. Options range across Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, and Midnight Firestorm in the black trim, with Billiard Gray, Vivid Black, and Blue Burst available in chrome trim. Lockable saddlebags with a combined capacity of two cubic feet extend the motorcycle’s utility while maintaining a streamlined silhouette.
A solo seat configuration is designed for rider stability during acceleration and cornering. This slim design contributes to the motorcycle’s 27-inch laden seat height, providing accessibility for a broad range of riders.
Rider Interface and Technology Integration
The rider interface incorporates updated controls and display systems designed for clear communication and adaptability. A new four-inch instrument display combines analog and digital elements. The analog speedometer maintains a traditional aesthetic, while the multifunction digital display provides information on ride modes, gear position, and tire pressure monitoring.
Three selectable ride modes allow riders to adjust performance characteristics to different conditions. Hand controls integrate these adjustments through repositioned switches that place ride mode selection and a flash-to-pass function within reach of the left forefinger. An adjustable brake lever provides customization for rider ergonomics.
A USB-C charging port is included, supporting extended rides by keeping mobile devices and Bluetooth® headsets powered. This feature ensures that navigation and communication tools remain operational without requiring external charging solutions.
Safety Technology and Electronic Assistance
Safety technology is integrated across multiple systems to support rider control under variable conditions. The base Anti-lock Brake System prevents wheel lock during urgent straight-line braking, maintaining stability during deceleration. Traction Control is designed to limit excessive rear wheel spin under acceleration, increasing confidence during throttle application.
Drag-Torque Slip Control reduces excessive rear wheel slip caused by abrupt downshifts or throttle reductions, particularly under wet or low-traction conditions. The Tire Pressure Monitoring System provides constant updates through the digital display, alerting the rider to pressure deviations that could impact performance or tire life.
The Cornering Rider Safety Enhancements expand these systems to account for lean angles and lateral forces. Cornering ABS modifies brake pressure for stability when the motorcycle is leaned into a turn. Cornering Traction Control adjusts power delivery to reduce slip during acceleration in cornering situations. Cornering Drag-Torque Slip Control maintains rear wheel stability during rapid downshifts while leaned over, further supporting rider control in complex scenarios.
