The 2026 Harley-Davidson® Low Rider® ST is engineered as a performance-oriented sport-touring motorcycle that integrates a high-output V-twin engine with a rigid chassis structure and rider-focused control systems. The model uses a Milwaukee-Eight® 117 High Output engine paired with a 6-speed transmission and a belt-driven final drive. Its structural dimensions, suspension configuration, and braking components are designed to support stability, handling precision, and consistent power delivery across a range of riding conditions.
The motorcycle measures 92.9 inches in length, 35 inches in width, and 50.8 inches in height. A laden seat height of 27 inches and an unladen height of 28.1 inches support rider accessibility while maintaining control. Ground clearance is measured at 5.7 inches, and the wheelbase extends to 63.6 inches, contributing to directional stability and balanced weight distribution.
Engine Configuration and Output Specifications
The Milwaukee-Eight® 117 High Output engine uses a pushrod-operated overhead valve system with four valves per cylinder and hydraulic self-adjusting lifters. This configuration reduces the need for manual valve adjustments while maintaining consistent operation under varying conditions. The engine displacement is 117 cubic inches, equivalent to 1,923 cubic centimeters.
The bore measures 4.075 inches, and the stroke is 4.5 inches, producing a compression ratio of 10.3 to 1. Fuel delivery is managed through Electronic Sequential Port Fuel Injection, ensuring precise fuel metering and combustion efficiency. The intake system includes a Heavy Breather intake with a washable synthetic media filter and an exposed element design. Exhaust gases are routed through a 2-into-1 exhaust system with a catalyst integrated into the header.
The engine produces 114 horsepower at 5,000 revolutions per minute and generates 128 foot-pounds of torque at 4,000 revolutions per minute. This output supports acceleration across low- and mid-range speeds without requiring frequent gear changes. The lubrication system uses a pressurized dry-sump configuration with an oil cooler to maintain temperature stability during extended operation.
Drivetrain Engineering and Gear Ratios
Power is transferred through a chain-driven primary system with a 34 to 46 ratio, followed by a belt-driven final drive with a 32 to 66 ratio. This combination balances durability with reduced maintenance compared to fully chain-driven systems. The clutch system is a mechanical, 10-plate wet clutch with assist functionality, which reduces lever effort and improves engagement smoothness.
The 6-Speed Cruise Drive® transmission provides a wide gear range for both acceleration and sustained cruising. The first gear ratio is 9.311, allowing for controlled initial acceleration. Second gear is set at 6.454, followed by third gear at 4.793. Fourth gear is 3.882, fifth gear is 3.307, and sixth gear is 2.79. These ratios support gradual power delivery while maintaining efficiency at higher speeds.
Chassis Structure and Suspension Design
The frame uses a mild steel tubular construction with a rectangular section backbone. The design incorporates stamped, cast, and forged junctions that are MIG welded to maintain structural integrity. Aluminum forged fender supports reduce weight while preserving strength. The swingarm also uses mild steel tubular sections with a stamped cross-member and forged axle junctions, contributing to consistent rear-wheel alignment and durability.
The front suspension consists of a 43 millimeter inverted fork with a single cartridge design and aluminum triple clamps. This setup improves front-end rigidity and steering precision. The rear suspension uses a hidden coil-over monoshock with a 56 millimeter stroke and hydraulic preload adjustment. This configuration allows for load adaptation without altering the fundamental suspension geometry.
Front suspension travel measures 5 inches, while rear suspension travel measures 4.4 inches. The steering geometry includes a rake angle of 28 degrees and a trail measurement of 5.7 inches. These values support predictable steering response and stability during both low-speed maneuvers and sustained highway travel.
Braking System and Wheel Configuration
The braking system uses dual front rotors measuring 11.8 inches in diameter with a thickness of 0.2 inches. These rotors are paired with 4-piston fixed calipers that provide consistent clamping force. The rear brake uses a single rotor measuring 11.5 inches in diameter and 0.23 inches in thickness, paired with a 2-piston floating caliper.
Anti-lock Braking System functionality is included as standard equipment. The system monitors wheel speed and adjusts braking pressure to prevent wheel lock during deceleration. This contributes to controlled stopping performance under varying traction conditions.
The motorcycle uses cast aluminum wheels with a radial design. The front wheel has a diameter of 19 inches and a width of 2.5 inches, while the rear wheel measures 16 inches in diameter with a width of 5 inches. Tires are Michelin® Scorcher 31 models, with a front specification of 110 over 90B19 and a rear specification of 180 over 70B16. These tire dimensions support traction, stability, and load distribution.
Dimensional Layout and Weight Distribution
The 2026 Harley-Davidson® Low Rider® ST has a running weight of 712 pounds and a shipped weight of 686 pounds. The Gross Vehicle Weight Rating is 1,160 pounds, with a front axle rating of 450 pounds and a rear axle rating of 730 pounds. These figures define the load capacity and structural limits of the motorcycle.
Fuel capacity is 5 gallons, with a reserve capacity of 1 gallon indicated by a warning light. Oil capacity with filter is 5 quarts, while the transmission holds 1 quart and the primary chain case holds 1.25 quarts. The absence of a liquid cooling system eliminates the need for coolant capacity.
Luggage capacity is measured at 2 cubic feet, supporting storage requirements for extended rides. The combination of fuel capacity and an estimated fuel economy of 47 miles per gallon allows for extended travel intervals between refueling.
Electrical System and Lighting Components
The electrical system includes a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp hours, with a cold cranking capacity of 310 CCA at 0 degrees Fahrenheit. Charging is handled by a three-phase system with a 48 amp output. The system produces 364 watts at 13 volts and 900 revolutions per minute, with a maximum output of 624 watts at 2,000 revolutions per minute.
The starting system uses a 1.6-kilowatt electric starter with a solenoid shift engagement mechanism. Lighting components are fully LED-based. The headlamp integrates a low beam, a high beam, and a signature position lamp. The tail and stop lamps use LED technology, and both front and rear turn signals are LED bullet-style units.
Instrumentation and Rider Interface Systems
The instrument cluster includes a 4-inch analog speedometer combined with a digital display. The display provides gear position, odometer readings, fuel level, ride mode indicators, heated gear status, traction control status, ABS status, tire pressure monitoring data, cruise control settings, a clock, trip information, range estimates, and tachometer indication.
The model includes a USB-C power outlet that provides 5 volts at 2.4 amps for device charging. The system does not include an integrated infotainment platform, navigation system, Bluetooth® connectivity, or audio components. This approach prioritizes essential rider information and reduces system complexity.
Rider Safety and Control Systems
The motorcycle includes several electronic rider-assist systems designed to improve stability and control. Anti-lock Braking System functionality is standard, along with a Traction Control System that manages rear-wheel slip during acceleration. A Drag-torque Slip Control System reduces rear-wheel instability during aggressive downshifting.
The Tire Pressure Monitoring System provides continuous feedback on tire pressure levels. Cornering-enhanced systems are also included, such as Cornering Enhanced ABS, Cornering Enhanced Traction Control, and Cornering Drag-torque Slip Control. These systems adjust performance parameters based on lean angle, contributing to stability during cornering maneuvers.
Lean angle capability is measured at 31.3 degrees on both the left and right sides. This supports controlled cornering without compromising ground clearance.
