The 2025 Harley-Davidson® Low Rider® ST is a sport-touring motorcycle designed for riders who prioritize performance, precision handling, and modern safety technology. Its design integrates heritage-inspired styling with a frame-mounted aerodynamic fairing, a high-output Milwaukee-Eight® V-twin engine, and a full suite of rider-focused features. Each component, from the exhaust configuration to the suspension geometry, is engineered to deliver efficient power delivery, improved cornering clearance, and reliable long-distance comfort.
Engine and Powertrain Performance
The Milwaukee-Eight® 117 High Output engine produces 114 horsepower and 128 foot-pounds of torque. This power unit benefits from a revised redline of 5,900 rpm, allowing for extended acceleration through higher engine speeds. The forward-facing Heavy Breather intake system increases airflow and optimizes intake tuning length to improve combustion efficiency and peak torque output. A two-into-one exhaust system, redesigned for improved symmetry and flow, contributes to performance gains in the mid and upper power ranges while maintaining a balanced aesthetic around the saddlebags. The result is a powertrain that delivers immediate throttle response while supporting sustained high-speed operation.
Suspension and Chassis Dynamics
The 2025 Harley-Davidson® Low Rider® ST features a tall monoshock rear suspension designed to increase cornering clearance and improve lean angle capability. This configuration, combined with a recalibrated suspension setup, provides stability during aggressive cornering and consistency during extended rides. The front end uses a 43-millimeter inverted fork that enhances rigidity, reduces flex under load, and delivers precise steering feedback. The combination of these elements ensures the chassis remains stable across varied road conditions while offering responsive control inputs.
Aerodynamic Fairing and Lighting Systems
A frame-mounted fairing, inspired by historic FXRT designs, has been engineered using computational fluid dynamics to optimize airflow management. The structure reduces rider fatigue at highway speeds by redirecting wind around the cockpit while maintaining high-speed stability. The lighting package includes a 146 mm headlamp for improved forward visibility, redesigned taillights, and LED turn signals for enhanced signaling clarity. The lighting system is designed to provide consistent illumination with minimal energy draw, ensuring optimal visibility in varying conditions.
Rider Interface and Control Features
The handlebar-mounted controls integrate ride mode selection, an adjustable brake lever, and a repositioned flash-to-pass switch located for quick access by the left forefinger. The instrumentation combines an analog speedometer with a four-inch multi-function digital display, presenting key data such as selected ride mode, tire pressure monitoring system status, gear position, and other operational details. The USB-C charging port allows for device connectivity and power supply during travel, supporting navigation and communication systems without interfering with the rider’s focus.
Safety and Stability Systems
The 2025 Harley-Davidson® Low Rider® ST is equipped with the Harley-Davidson® Rider Safety Enhancements, which incorporate multiple electronically managed systems to improve stability and control. The Anti-lock Brake System helps prevent wheel lock during straight-line braking, while Cornering Enhanced ABS adjusts braking force based on lean angle. The Traction Control System limits rear wheel slip during acceleration, and its cornering-enhanced variant adapts this function during leaned turns. Drag-Torque Slip Control reduces excessive rear wheel slip during abrupt downshifts or rapid throttle closures, with a cornering-specific version that accounts for lean angle and side-to-side movement. The Tire Pressure Monitoring System alerts the rider to deviations in pressure, helping maintain tire integrity and consistent handling performance.
Frame Geometry and Handling Characteristics
The motorcycle’s frame geometry supports stability during high-speed cruising and agility in tight turns. The tall rear suspension raises the tail profile, which improves approach and departure angles during cornering. Combined with the aerodynamic fairing and precision-engineered chassis, the geometry provides a balance between comfort on long straight sections and responsiveness in technical riding situations. The design accommodates a solo seat layout, ensuring rider positioning remains consistent under acceleration and braking forces.
Braking Components and Wheel Setup
Dual front brake discs provide high braking capacity with consistent modulation. This braking setup, paired with the traction and slip control systems, helps maintain predictable deceleration across varying road conditions. The 2025 Harley-Davidson® Low Rider® ST is fitted with Michelin® Scorcher® 31 tires, chosen for their grip, wear resistance, and compatibility with the suspension tuning. These tires contribute to the motorcycle’s stable handling in both wet and dry conditions.
Storage Integration and Functional Design Elements
The model includes lockable saddlebags with a total storage capacity of two cubic feet. The saddlebags are integrated into the motorcycle’s rear design to maintain aerodynamic efficiency and visual balance. Their placement ensures easy access without disrupting the motorcycle’s lean angle capabilities. Premium paint options and retro-inspired graphics connect the motorcycle to its heritage while preserving its functional sport-touring role. Available trim packages include blacked-out or chrome finishes, with color options such as Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, Midnight Firestorm, and Blue Burst.
Instrumentation and Ride Customization
The digital and analog hybrid display system enables quick reference to key operational metrics while riding. The inclusion of selectable ride modes allows the rider to tailor throttle response, traction management, and braking support to match specific riding environments. These modes are accessed directly from the left-hand control cluster, ensuring adjustments can be made without removing focus from the road. The system also integrates gear position indicators, odometer readings, and trip data for complete ride tracking.
Technical Specifications Summary
The motorcycle’s laden seat height is measured at 27 inches, providing accessibility while maintaining sufficient ground clearance for aggressive lean angles. Fuel economy is rated at 47 miles per gallon, balancing performance with efficiency for longer touring ranges. The combination of engine tuning, aerodynamic improvements, and suspension design produces a sport-touring platform capable of consistent performance over extended distances.
Ride Preparation and Operational Efficiency
The component placement and mechanical layout of the 2025 Harley-Davidson® Low Rider® ST facilitate ease of maintenance and operational readiness. Key systems such as the exhaust, intake, and electronics are arranged to allow for efficient inspection and adjustment. The electrical system supports both the core riding functions and auxiliary device charging through the USB-C port, maintaining operational reliability over extended use.
