Engine Power and Performance Engineering
The 2025 Harley-Davidson® Low Rider® ST is equipped with the Milwaukee-Eight® 117 High Output V-Twin engine, producing 114 horsepower and 128 foot-pounds of torque. This updated powertrain is designed for stronger mid-range acceleration and sustained top-end strength. A raised 5,900 rpm redline allows longer throttle engagement without mechanical stress, resulting in consistent power distribution across the full operating range.
The Heavy Breather intake system channels air forward to maximize combustion efficiency and optimize intake tuning length. This improves torque response and provides smooth power delivery across all speed ranges. The two-into-one exhaust system complements this setup by maintaining visual symmetry with the saddlebags while promoting efficient exhaust flow. This contributes to improved throttle response and a cleaner power curve.
The Milwaukee-Eight® 117 H.O. maintains stable output under varying load conditions through its advanced air and oil-cooling system. This configuration limits heat buildup and ensures durability over extended operation. Engine calibration has been refined to deliver reliable torque response through every gear, producing a controlled and predictable feel during both acceleration and deceleration.
Suspension and Ride Geometry
The chassis and suspension system are designed for agility and comfort. A tall rear monoshock increases cornering clearance, allowing improved lean angles while keeping the motorcycle stable during aggressive turns. The 43mm inverted front fork provides accurate steering feedback and predictable handling. This design ensures consistent control in both high-speed travel and low-speed maneuvers.
The suspension geometry supports a balance between performance responsiveness and rider comfort. Increased suspension travel enhances impact absorption and stability across different surfaces. Dual 300mm front brake discs supply strong and reliable braking performance while resisting fade during prolonged use. Combined with Michelin® Scorcher® 31 tires, the motorcycle maintains excellent grip and braking stability under various road conditions.
The rigid frame structure and low 27-inch laden seat height provide a low center of gravity. This design improves control at lower speeds and ensures even weight distribution through corners. The combined effect of the suspension and geometry delivers steady handling for touring and performance riding alike.
Aerodynamic Refinement and Exterior Design
The 2025 Harley-Davidson® Low Rider® ST uses a frame-mounted FXRT-style fairing developed with Computational Fluid Dynamics (CFD) to improve aerodynamic efficiency. The fairing directs airflow around the rider, reducing fatigue and maintaining stability during highway travel. This design reduces wind turbulence while supporting consistent control in changing wind conditions.
Lighting performance is enhanced through full LED integration. A 146mm headlight, a redesigned taillight, and LED turn indicators improve visibility and reliability. The LED system provides clear illumination with lower power draw compared to conventional lighting.
Premium paint finishes and heritage-inspired graphics maintain the brand’s design tradition. The 2025 Harley-Davidson® Low Rider® ST is available in two trims. The Black Trim option includes Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, and Midnight Firestorm. The Chrome Trim version features Billiard Gray, Vivid Black, and Blue Burst.
The slim solo seat provides stable rider positioning under acceleration and during cornering. Combined with the ergonomic control layout, it allows natural weight balance and firm seating for precision handling. Every design element is functional, contributing to both rider comfort and aerodynamic balance.
Integrated Ride Technology
The 2025 Harley-Davidson® Low Rider® ST features a 4-inch instrument display that combines an analog speedometer with a multifunction digital screen. The display presents ride mode selection, gear position, tire pressure, and trip information in a clear and accessible format. The interface allows quick information access while minimizing rider distraction.
Three selectable ride modes allow customization of performance characteristics. Riders can adapt throttle response and traction sensitivity based on preference or road conditions. Each mode adjusts the motorcycle’s behavior to maintain consistent control during acceleration or deceleration.
Newly developed hand controls include a repositioned flash-to-pass switch, an adjustable brake lever, and improved mode selection toggles. The simplified layout enhances ease of operation and accessibility.
A USB-C charging port supports on-the-go power for navigation or communication devices. This system provides continuous charging capability and ensures reliable connectivity during extended rides.
Advanced Safety Systems
The 2025 Harley-Davidson® Low Rider® ST is equipped with the Harley-Davidson® Rider Safety Enhancements, a comprehensive suite of electronic systems designed to optimize traction, braking, and stability.
The Anti-lock Brake System (ABS) prevents wheel lock under heavy braking, helping the rider maintain steering control during straight-line stops. The Traction Control System (TCS) limits rear-wheel spin during acceleration by adjusting power delivery to maintain grip. The Drag-Torque Slip Control System (DSCS) reduces rear-wheel slip caused by abrupt downshifts or throttle reductions, improving stability on wet or uneven surfaces.
The Cornering Enhanced Anti-lock Brake System (C-ABS) and Cornering Enhanced Traction Control System (C-TCS) further refine stability by taking lean angle into account. These systems modify brake pressure and throttle response to preserve traction during cornering. The Cornering Drag-Torque Slip Control System (C-DSCS) manages rear-wheel stability when decelerating or shifting mid-turn, particularly on low-friction surfaces.
A Tire Pressure Monitoring System (TPMS) continuously measures and displays tire pressure, alerting the rider to any variation from recommended levels. Proper tire pressure improves handling predictability and extends tire lifespan.
Each of these systems functions automatically, allowing the rider to focus on the road while the motorcycle adjusts to traction and stability variables. Together, they provide consistent performance without interfering with the natural riding experience.
Structural Design and Mechanical Efficiency
The structure of the 2025 Harley-Davidson® Low Rider® ST is designed for strength and balance. The frame-mounted fairing integrates smoothly with 2-cubic-foot lockable saddlebags that preserve aerodynamic efficiency while providing practical storage. The saddlebags are built for security, weather resistance, and easy access.
