2022–2024 Harley-Davidson Softail Milwaukee-Eight 117 (FXLRST Low Rider ST)

Development and Design

The Low Rider ST builds upon the foundation of the existing Low Rider S (FXLRS) model. Its design is a modern factory interpretation of the custom bikes that gained popularity for their blend of speed and utility. The most prominent feature is the new frame-mounted fairing, a design inspired by the classic FXRT Sport Glide model from the 1980s. Unlike the fork-mounted fairings on models like the Street Glide, a frame-mounted fairing affixes directly to the motorcycle’s frame. This design reduces the effect of wind buffeting on the handlebars, contributing to improved stability at higher speeds.

Complementing the fairing are a pair of high-mounted, rigid, and lockable clamshell saddlebags. These bags are designed for easy removal, allowing the rider to quickly convert the motorcycle from a light-duty tourer to a stripped-down cruiser. The ergonomics are defined by a solo seat, mid-mount foot controls, and moto-style handlebars on tall risers, creating an upright and commanding riding position. Visual styling is finished with signature Matte Dark Bronze cast aluminum wheels and a blacked-out powertrain and exhaust system.

Powertrain and Performance of the Harley-Davidson Softail Milwaukee-Eight 117 (FXLRST Low Rider ST)

At the heart of the Low Rider ST is the Milwaukee-Eight 117 V-Twin engine. At its launch in 2022, this was the most powerful, largest-displacement engine offered by Harley-Davidson in a production Softail model. The 117 cubic inch (1923cc) air- and oil-cooled engine features a high-performance camshaft, a high-flow intake, and a 2-into-2 offset shotgun exhaust designed to maximize torque output. This powertrain is tuned for strong low- to mid-range acceleration, providing immediate power for city riding and highway overtaking. The engine is rigid-mounted to the frame and utilizes dual counter-balancers to minimize vibration at idle and while riding, enhancing rider comfort over long distances.

Chassis, Suspension, and Handling

The Low Rider ST utilizes Harley-Davidson’s Softail frame, which emulates the clean lines of a vintage hardtail frame but conceals a modern monoshock rear suspension for a comfortable and controlled ride. To enhance its performance capabilities, the ST features specific suspension tuning. The front suspension consists of a 43mm inverted fork, providing rigidity and precise handling.

The rear suspension features a taller monoshock than the standard Low Rider S, which increases rear wheel travel and provides a 1.3-degree steeper rake. This adjustment raises the rear of the motorcycle, improving cornering clearance and allowing for more aggressive lean angles before hard parts make contact with the pavement. Braking is handled by dual front disc brakes with 4-piston calipers and a single rear disc, with Anti-Lock Braking System (ABS) as a standard feature.

Differences from the Low Rider S (FXLRS)

While sharing a common platform, the Low Rider ST is differentiated from its contemporary, the Low Rider S (FXLRS), by several key features intended for different riding purposes.
