The 2026 Harley-Davidson® Low Rider® ST is a performance-oriented motorcycle that combines a Milwaukee-Eight® 117 High Output engine, a purpose-built chassis, advanced rider assistance technologies, and integrated touring functionality. Designed around a balance of power delivery, handling capability, and long-distance practicality, the model incorporates modern braking systems, suspension components, electronic rider aids, and functional storage capacity. Its specifications reflect a focus on strong engine output, responsive chassis geometry, and a rider interface that provides access to essential operating information.
Engine and Powertrain
The 2026 Harley-Davidson® Low Rider® ST is powered by the Milwaukee-Eight® 117 High Output engine, a V-twin powerplant with a displacement of 117 cubic inches, or 1,923 cubic centimeters. The engine uses a pushrod-operated overhead valve design with hydraulic self-adjusting lifters and four valves per cylinder. This configuration supports consistent valve operation while reducing routine adjustment requirements. With a bore of 4.075 inches and a stroke of 4.5 inches, the engine is engineered to deliver substantial output across its operating range. A compression ratio of 10.3:1 further defines the engine's operating characteristics and contributes to its overall performance profile.
Electronic Sequential Port Fuel Injection manages fuel delivery throughout the engine's operating range. This system works in conjunction with the Heavy Breather intake, which features synthetic filter media and a washable exposed element. The intake system is designed to provide efficient airflow while allowing serviceability through its reusable filter element. Exhaust gases are routed through a 2-into-1 exhaust system that incorporates a catalyst in the header. Engine lubrication is handled by a pressurized dry-sump system equipped with an oil cooler, supporting thermal management and lubrication performance during operation.
Output and Performance Characteristics
The Milwaukee-Eight® 117 High Output engine produces a rated 114 horsepower at 5,000 rpm and 128 ft-lb of torque at 4,000 rpm. These figures highlight the engine's ability to deliver substantial rotational force and strong acceleration characteristics throughout the operating range. Torque measurements are certified using the J1349 testing methodology, providing a standardized reference for performance evaluation. The engine's output is matched to the motorcycle's drivetrain and chassis design to create a cohesive riding experience. Together, these specifications establish the 2026 Harley-Davidson® Low Rider® ST as a motorcycle with significant power available across a broad range of operating conditions.
Lean-angle capability is another notable aspect of the model's performance profile. The motorcycle achieves a measured lean angle of 31.3 degrees on both the right and left sides. Testing is conducted according to the J1168 methodology, providing a consistent standard for measurement. Equal lean-angle figures on both sides contribute to balanced cornering characteristics. Combined with the motorcycle's chassis geometry and suspension components, these figures help define its handling capability.
Drivetrain and Transmission
The drivetrain of the 2026 Harley-Davidson® Low Rider® ST is built around a chain primary drive with a 34/46 ratio and a belt final drive using a 32/66 ratio. This combination transfers power from the engine to the rear wheel through a durable mechanical system designed for consistent operation. The final belt drive contributes to the motorcycle's overall drivetrain configuration while working in conjunction with the transmission and clutch assembly. Each component is engineered to complement the engine's output and torque characteristics.
Clutch and Gear Ratios
A mechanical 10-plate wet clutch with assist and conventional functionality manages power transfer between the engine and transmission. This clutch configuration is designed to support engagement consistency and effective power delivery. The transmission is a 6-Speed Cruise Drive® unit that provides six forward gear ratios. Overall gearing is specified at 9.311 in first gear, 6.454 in second gear, 4.793 in third gear, 3.882 in fourth gear, 3.307 in fifth gear, and 2.79 in sixth gear. The progression of these ratios allows the engine's output to be effectively utilized across a range of riding situations while maintaining compatibility with the motorcycle's performance-oriented character.
Chassis and Structural Engineering
The chassis of the 2026 Harley-Davidson® Low Rider® ST is based on a mild-steel tubular frame featuring a rectangular-section backbone. The frame incorporates stamped, cast, and forged junctions that are joined through MIG welding processes. Aluminum-forged fender supports are also integrated into the structure. This combination of materials and construction methods contributes to the motorcycle's overall rigidity and structural design. The frame serves as the foundation for the engine, suspension, and rider interface systems.
The swingarm uses mild-steel tubular sections combined with a stamped cross-member and forged axle junctions. Like the frame, the swingarm is MIG welded and includes a removable belt spacer. The design supports the rear suspension system and drivetrain while contributing to the motorcycle's handling characteristics. Together, the frame and swingarm establish the structural platform upon which the 2026 Harley-Davidson® Low Rider® ST is built.
Dimensions and Geometry
The motorcycle measures 92.9 inches in overall length, 35 inches in width, and 50.8 inches in height. Its wheelbase extends 63.6 inches, creating a substantial platform that supports stability and rider accommodation. The steering geometry includes a 28-degree rake and a 28-degree fork angle, complemented by 5.7 inches of trail. These measurements define the motorcycle's steering characteristics and contribute to its overall handling behavior.
Seat height is listed at 27 inches when laden and 28.1 inches when unladen. Static ground clearance measures 5.7 inches. These dimensions influence rider accessibility and motorcycle positioning while stationary and in operation. Combined with the wheelbase and steering geometry, they contribute to the overall riding posture and dynamic characteristics of the motorcycle.
Suspension, Wheels, and Tires
The suspension system of the 2026 Harley-Davidson® Low Rider® ST combines modern front and rear components designed to support handling performance and ride quality. At the front, the motorcycle uses a single-cartridge 43 mm inverted fork with aluminum fork triple clamps and a single-rate spring. This arrangement is designed to provide controlled suspension movement and precise steering response. The inverted design places significant structural components higher within the assembly, contributing to the overall suspension architecture.
At the rear, suspension duties are managed by a hidden free-piston coil-over monoshock featuring 56 mm of stroke and hydraulic preload adjustment. The preload adjustment capability allows suspension settings to be modified to accommodate changing operating requirements. Front suspension travel measures 5 inches, while rear suspension travel measures 4.4 inches. Together, these components define the motorcycle's suspension performance and ride characteristics.
