Engine Performance and Powertrain
The 2026 Harley-Davidson® Low Rider® ST is powered by the Milwaukee-Eight® 117 High Output engine, a large-displacement V-twin with a certified displacement of 117 cubic inches, or 1,923 cubic centimeters. The engine features a bore of 4.075 inches and a stroke of 4.5 inches, producing a substantial displacement that supports strong output characteristics throughout the operating range. A compression ratio of 10.3:1 contributes to the engine's performance profile while working in conjunction with the electronic fuel injection system. Harley-Davidson® rates the engine at 128 ft-lb of torque at 4,000 rpm and 114 horsepower, or 85 kW, at 5,000 rpm.
Engine Architecture and Induction System
The Milwaukee-Eight® 117 High Output engine utilizes pushrod-operated overhead valves with hydraulic self-adjusting lifters and four valves per cylinder. This design minimizes routine valve adjustment requirements while supporting efficient airflow through the combustion chambers. Fuel delivery is managed by Electronic Sequential Port Fuel Injection, which provides precise fuel metering across operating conditions. Air enters the engine through a Heavy Breather intake that incorporates synthetic filter media and a washable exposed element. This intake arrangement forms an important component of the engine's airflow system and complements the overall powertrain design.
Exhaust and Lubrication Systems
Exhaust gases are routed through a 2-into-1 exhaust system that incorporates a catalyst within the header assembly. The compact design supports the engine package while maintaining the specified exhaust configuration for the model. Engine lubrication is handled by a pressurized dry-sump system equipped with an oil cooler. This arrangement stores and circulates oil separately from the crankcase while helping maintain lubrication consistency during operation. Together, the lubrication and exhaust systems contribute to the motorcycle's overall mechanical package and support sustained engine performance.
Transmission and Drivetrain
The drivetrain of the 2026 Harley-Davidson® Low Rider® ST is engineered to transfer the output of the Milwaukee-Eight® 117 High Output engine through a combination of chain and belt drive components. Primary drive duties are handled by a chain system with a 34/46 ratio, while the final drive utilizes a belt with a 32/66 ratio. This drivetrain arrangement works in conjunction with a mechanical 10-plate wet clutch featuring assist and conventional operation. The design provides a direct connection between engine output and rear-wheel power delivery while maintaining the specified drivetrain configuration for the model.
Six-Speed Cruise Drive® Transmission
Power is managed through a 6-Speed Cruise Drive® transmission that offers six forward gear ratios. The overall first-gear ratio is 9.311, followed by ratios of 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. This progression provides a structured range of gearing that supports acceleration and cruising operation. The transmission functions as a key component of the motorcycle's performance package by translating engine output into usable road speed. Its integration with the clutch and final drive system creates a complete drivetrain package designed around the capabilities of the Milwaukee-Eight® 117 High Output engine.
Chassis Design and Structural Engineering
The chassis of the 2026 Harley-Davidson® Low Rider® ST uses a mild steel tubular frame featuring a rectangular-section backbone. The frame incorporates stamped, cast, and forged junctions that are assembled using MIG welding techniques. Aluminum forged fender supports further contribute to the structure while reducing the complexity of supporting components.
Swingarm Construction and Geometry
The motorcycle utilizes a mild steel swingarm constructed from tubular sections and a stamped cross-member. Forged axle junctions and MIG-welded assembly contribute to the structural design, while a removable belt spacer supports final drive serviceability.
