The 2025 Harley-Davidson® Low Rider® ST is a purpose-built motorcycle designed for riders seeking a performance-focused platform with long-distance touring capacity. Developed around the Milwaukee-Eight® 117 High Output engine, a reinforced frame-mounted fairing, and integrated rider assist technologies, this model combines mechanical control with sustained highway comfort. Its design pulls from the FXRT fairing legacy, now applied with modern aerodynamic development and hardware advancements. Every detail, from ride modes to the saddlebag layout, contributes to a touring motorcycle that maintains handling precision under throttle and at lean.
High Output Engine with Focused Power Delivery
The Milwaukee-Eight® 117 High Output engine in the 2025 Harley-Davidson® Low Rider® ST provides direct improvements in acceleration and torque curve responsiveness. The redline is increased from the standard 5,600 rpm to 5,900 rpm. The forward-facing Heavy Breather intake increases air volume and tuning length, improving charge efficiency and peak torque.
The two-into-one exhaust system is designed for airflow optimization and overall symmetry. It reduces heat retention while also ensuring visual balance when combined with the hard-case saddlebags.
Engine output reaches 114 horsepower, paired with 128 foot-pounds of torque.
Suspension Design with Cornering Functionality
The 2025 Harley-Davidson® Low Rider® ST includes a revised rear monoshock with increased height. The front suspension includes a 43mm inverted fork that maintains stability under braking and cornering loads. Damping is adjusted for performance use, with emphasis on keeping the chassis neutral during acceleration out of turns or under mid-corner adjustments.
Dual 300mm disc brakes up front provide consistent braking performance without excessive lever force. Combined with the Michelin® Scorcher® 31 tire setup, the overall chassis system is tuned for front-end control, mid-corner grip, and braking accuracy.
Aerodynamic Front End and Visibility Components
The 2025 Harley-Davidson® Low Rider® ST features a frame-mounted fairing modeled on the FXRT design, updated using computational fluid dynamics. Unlike fork-mounted alternatives, this configuration provides consistent aerodynamics regardless of steering input. The fairing is secured independently from the handlebars, which helps maintain line stability at higher speeds or during gusting conditions.
The lighting system includes a 5.75-inch LED headlamp, integrated LED turn signals, and a redesigned LED tail unit. All lighting units are integrated into the frame or body panels to reduce disruption of airflow.
Rider Interface with Digital Integration
Rider inputs and data feedback are centered around a four-inch display located below the analog speedometer. This multifunction screen provides real-time data for tire pressure monitoring, gear position, ride mode status, and system diagnostics. The unit is designed to remain legible in daylight conditions and responds to hand control toggles.
Revised hand controls include a repositioned flash-to-pass switch on the left grip, located for easier index finger access. The brake lever is adjustable, which allows for better reach calibration based on rider preference and hand size.
A USB-C charging port is integrated into the dashboard for direct connection to navigation units, communication headsets, or mobile devices. Power output is consistent regardless of engine rpm, allowing accessories to remain functional while idling or riding at low speeds.
Selectable Ride Modes and Dynamic Assist Systems
The 2025 Harley-Davidson® Low Rider® ST includes three selectable ride modes that adjust throttle response, traction intervention, and system behavior. These modes adapt to road surface conditions, riding style, and cargo load. The system is connected to the digital display and allows on-the-fly switching when conditions change.
The suite of Rider Safety Enhancements includes advanced systems designed to respond to both surface traction and lean angle conditions. Anti-lock Brake System maintains wheel rotation under hard braking. Traction Control prevents wheel spin during acceleration and adjusts throttle application when slip is detected. Drag-Torque Slip Control reduces sudden wheel slip during downshifts or rapid deceleration.
Cornering variants of these systems apply lean angle sensors to refine intervention. Cornering ABS adapts brake force based on lateral pressure during turns. Cornering Traction Control accounts for side-to-side dynamics during throttle application. Cornering Drag-Torque Slip Control responds to the same conditions when throttle is closed mid-corner or under sudden engine braking.
Tire Pressure Monitoring is integrated directly into the display. The system alerts the rider to high or low pressure that could affect grip, fuel economy, or tire lifespan. The sensors operate in real time and require no manual calibration from the rider.
Chassis Geometry and Touring Ergonomics
The motorcycle uses a solo seat design with a shaped rear bolster. Seat height is 27 inches when laden, allowing for secure flat-foot stops and low center of gravity feel.
The saddlebags provide two cubic feet of storage. These units are hard-cased and lockable. They are molded to match the tail lines and fit closely around the exhaust. The bags are positioned to avoid interference with rear suspension movement or rider legroom.
The overall riding position includes mid-mount controls, slightly forward handlebars, and a low-mounted fuel tank. Foot positioning supports cornering transitions and allows consistent control during longer durations in the saddle.
Paint Finishes and Visual Configuration
Color options include Billiard Gray, Vivid Black, Iron Horse Metallic, Brilliant Red, and Midnight Firestorm in the blacked-out trim. A chrome trim variant is also available with Blue Burst and additional finish options. Paint application includes retro-inspired tank graphics with modern gloss and durability treatments.
The 2025 Harley-Davidson® Low Rider® ST updates include a stylized rear taillight, integrated turn signal units, and revised paint combinations for both trims.
