High-Output Milwaukee-Eight® 117 Engine Configuration
The 2025 Harley-Davidson® Low Rider® ST is powered by the Milwaukee-Eight® 117 High Output V-twin engine, an air-cooled and oil-cooled powerplant designed for increased mid-range and upper-range performance. This engine delivers a factory-rated 114 horsepower and 128 ft-lb of torque, placing it among the most powerful production engines offered within the Harley-Davidson® cruiser-based lineup. The High Output designation reflects internal tuning differences that prioritize sustained acceleration and extended rev capability.
A revised camshaft profile and recalibrated valve timing improve airflow efficiency during higher engine speeds. The redline has been increased from 5,600 rpm to 5,900 rpm, allowing the engine to maintain power delivery longer during hard acceleration. These changes result in improved throttle response during passing maneuvers and aggressive riding conditions while maintaining consistent output across the powerband.
Fuel economy is rated at approximately 47 miles per gallon under standard operating conditions, supporting longer riding intervals without compromising engine output. The balance between power and efficiency reflects the intended dual-purpose nature of the 2025 Harley-Davidson® Low Rider® ST as a performance machine with touring range capability.
Air Intake and Exhaust Flow Optimization
Air management plays a central role in the performance profile of the 2025 Harley-Davidson® Low Rider® ST. The motorcycle is equipped with a Heavy Breather forward-facing intake system engineered to maximize airflow volume and optimize intake tuning length. This configuration improves cylinder filling efficiency and contributes to peak torque output during acceleration. The intake design also supports consistent throttle response across varying engine speeds.
Exhaust gases are routed through a two-into-one exhaust system that enhances exhaust scavenging and supports balanced power delivery. The exhaust layout contributes to improved mid-range performance while maintaining a compact profile that integrates cleanly with the motorcycle’s hard saddlebags. This design choice preserves ground clearance and lean angle while supporting functional storage capacity.
Chassis Architecture and Suspension Calibration
The 2025 Harley-Davidson® Low Rider® ST utilizes a rigid frame structure designed to support high-output performance and stable handling characteristics. The suspension system is calibrated to balance comfort with aggressive riding capability. A tall rear monoshock raises the rear ride height, increasing cornering clearance and improving weight transfer during acceleration and braking.
Front suspension is handled by an inverted fork that provides controlled damping and improved feedback during corner entry and braking. This setup contributes to predictable steering behavior and consistent tire contact under varying load conditions. The overall chassis geometry supports confident handling during both straight-line cruising and dynamic cornering scenarios.
The laden seat height measures approximately 27 inches, maintaining accessibility while preserving the motorcycle’s performance-focused stance. This dimension supports stable footing at stops without sacrificing suspension travel or chassis rigidity.
Aerodynamic Fairing Design and Wind Management
A defining feature of the 2025 Harley-Davidson® Low Rider® ST is its frame-mounted fairing inspired by the FXRT design lineage. Unlike fork-mounted fairings, this configuration attaches directly to the frame, isolating steering input from aerodynamic forces. This design improves stability at highway speeds and reduces steering effort in crosswind conditions.
The fairing has been shaped using computational fluid dynamics to manage airflow efficiently around the rider. Wind pressure is reduced without creating excessive turbulence, supporting sustained highway travel while maintaining a compact frontal area. The fairing design contributes to reduced rider fatigue and improved high-speed composure.
Lighting Systems and Exterior Components
The 2025 Harley-Davidson® Low Rider® ST is equipped with full LED lighting, including a 5.75-inch LED headlamp, LED turn signals, and a redesigned LED taillight. These components improve visibility and signaling clarity while reducing electrical load. LED lighting also offers increased durability and consistent illumination over extended operating periods.
Exterior components emphasize functional integration. Hard, lockable saddlebags provide approximately 2 cubic feet of combined storage capacity. The saddlebags are positioned to maintain balanced weight distribution and do not interfere with exhaust routing or suspension movement. Their rigid construction supports secure storage during extended rides.
A slim solo seat is fitted as standard, designed to hold the rider in position during acceleration and cornering. The seat profile supports active riding posture and contributes to overall control without adding unnecessary bulk.
Instrumentation and Control Interface
Rider information is delivered through a 4-inch instrument display that combines an analog speedometer with a multifunction digital screen. The display provides access to ride data such as gear position, engine speed, fuel level, tire pressure monitoring, and system alerts. Information is presented clearly to minimize distraction during operation.
Updated hand controls allow direct access to ride mode selection and other functions. The brake lever is adjustable to accommodate rider preference, and the flash-to-pass switch has been repositioned for improved accessibility. These changes enhance ergonomic efficiency and operational control.
A USB-C charging port is included to support electronic devices used for navigation or communication. This feature ensures compatibility with current device standards and supports extended riding sessions.
Ride Modes and Electronic Management Systems
The 2025 Harley-Davidson® Low Rider® ST features three selectable ride modes that adjust throttle response and traction control behavior. These modes allow the motorcycle’s electronic systems to adapt to different riding conditions and rider preferences. Mode selection is integrated into the control interface for ease of use.
Electronic management systems operate continuously to balance power delivery and wheel traction. These systems function in the background, providing consistent performance without requiring active rider intervention.
Comprehensive Rider Safety Enhancements
The 2025 Harley-Davidson® Low Rider® ST is equipped with a full suite of Rider Safety Enhancements designed to assist during braking, acceleration, and deceleration. Anti-lock Brake System technology helps prevent wheel lock during emergency braking situations in straight-line conditions. Traction Control System functionality manages rear-wheel slip during acceleration to maintain stability.
Drag-Torque Slip Control System operation reduces the risk of rear-wheel lock during abrupt downshifts or rapid throttle reduction, particularly on low-traction surfaces. These systems work together to support controlled operation across varying road conditions.
Cornering-enhanced versions of these systems further refine performance by adjusting intervention levels based on lean angle. Cornering-enhanced ABS, traction control, and drag-torque slip control account for lateral forces during cornering, allowing the motorcycle to maintain stability while leaned over.
A Tire Pressure Monitoring System continuously measures tire pressure and provides alerts through the instrument display. Maintaining proper tire pressure supports handling consistency, braking performance, and tire longevity.
Structural Integration and Touring Capability
The 2025 Harley-Davidson® Low Rider® ST is engineered to support extended riding without adopting a full touring platform. Structural integration of the fairing, saddlebags, and exhaust system maintains chassis balance and preserves performance characteristics. Storage capacity is sufficient for multi-day travel while retaining the motorcycle’s aggressive profile.
The combination of aerodynamic management, suspension calibration, and electronic assistance supports sustained highway operation without compromising responsiveness during technical riding scenarios. These characteristics define the 2025 Harley-Davidson® Low Rider® ST as a purpose-built sport-touring motorcycle rather than a modified cruiser.
