The 2026 Harley-Davidson® Low Rider® S is designed as a performance-oriented cruiser that combines high-displacement engine output with a structurally rigid chassis and integrated electronic rider systems. The model incorporates a Milwaukee-Eight® 117 High Output engine, paired with a six-speed transmission and a Softail® frame architecture. Its configuration prioritizes torque delivery, controlled handling geometry, and consistent braking response. The motorcycle also integrates rider-assist systems that support traction, braking stability, and monitoring functions without adding unnecessary complexity.
High-Output Engine Specifications and Combustion Design
The 2026 Harley-Davidson® Low Rider® S is equipped with the Milwaukee-Eight® 117 High Output engine, a V-twin configuration with a displacement of 117 cubic inches, or 1,923 cubic centimeters. The engine uses a bore of 4.075 inches and a stroke of 4.5 inches, producing a compression ratio of 10.3 to 1. This setup supports efficient combustion and sustained output across a defined RPM range.
The engine generates 128 foot-pounds of torque at 4,000 rpm and delivers 114 horsepower at 5,000 rpm. These values indicate a torque-focused powerband that supports acceleration and mid-range responsiveness. The valvetrain consists of pushrod-operated overhead valves with hydraulic self-adjusting lifters. Each cylinder contains four valves, which improves airflow and combustion efficiency while reducing maintenance requirements.
Fuel delivery is managed through Electronic Sequential Port Fuel Injection. This system meters fuel precisely based on engine demand, contributing to consistent throttle response. The air intake system uses a Heavy Breather configuration with a washable exposed filter element. This design allows increased airflow into the combustion chamber.
The exhaust system is a two-into-one configuration with a catalyst located in the header. This supports exhaust flow efficiency while maintaining emissions compliance. The lubrication system is a pressurized dry-sump design with an integrated oil cooler. This arrangement maintains oil circulation and temperature control during extended operation.
Transmission and Drivetrain Configuration
Power transfer is managed through a combination of chain-driven and belt-driven systems. The primary drive uses a chain with a 34 to 46 ratio. The final drive uses a belt with a 32 to 66 ratio, offering durability and reduced maintenance compared to chain-only systems.
The motorcycle uses a mechanical, ten-plate wet clutch with assist functionality. This reduces lever effort and improves engagement consistency. The transmission is a six-speed Cruise Drive® system designed to accommodate a wide operating range.
Gear ratios are configured to balance acceleration and cruising efficiency. First gear has a ratio of 9.311, supporting initial movement and low-speed control. Second through sixth gears are spaced progressively, with ratios of 6.454, 4.793, 3.882, 3.307, and 2.79. This arrangement allows smooth transitions between speeds while maintaining engine efficiency.
Structural Frame and Chassis Composition
The frame is constructed from mild steel using a tubular design with a rectangular backbone. It incorporates stamped, cast, and forged junctions that are MIG welded to form a rigid structure. Aluminum forged fender supports are included to reduce weight without compromising durability.
The swingarm is also made of mild steel and uses tubular sections with a stamped cross-member. Forged axle junctions enhance strength at key stress points. The swingarm includes a removable belt spacer, supporting drivetrain maintenance and alignment.
Suspension System and Ride Control
Front suspension is handled by a 43-millimeter inverted fork with a single cartridge design. Aluminum triple clamps support the fork assembly, contributing to rigidity and steering precision. The fork uses a single-rate spring configuration.
The rear suspension uses a hidden coil-over monoshock with a free piston design. The shock provides 56 millimeters of stroke and includes hydraulic preload adjustment. This allows the rider to modify suspension characteristics based on load conditions.
Suspension travel measures 5 inches at the front and 4.4 inches at the rear. These values provide a balance between comfort and control. The suspension system is tuned to maintain tire contact with the road surface while managing vertical movement.
Dimensions, Geometry, and Rider Positioning
The overall length of the motorcycle is 92.9 inches, with a width of 35 inches and a height of 47.4 inches. The wheelbase measures 63.6 inches, supporting straight-line stability and predictable handling.
The seat height is 27 inches when laden and 28.1 inches when unladen. This low seat height contributes to accessibility and rider confidence during stops. Ground clearance is measured at 5.7 inches, allowing for moderate lean angles.
The steering geometry includes a rake angle of 28 degrees and a trail measurement of 5.7 inches. These values influence steering response and stability. The configuration supports controlled cornering and consistent directional input.
Wheels, Tires, and Road Contact
The 2026 Harley-Davidson® Low Rider® S uses Michelin® Scorcher 31 tires for both front and rear applications. The front tire is sized at 110 over 90 B19, while the rear tire is sized at 180 over 70 B16. These tire dimensions provide a balance between grip and durability.
Wheels are constructed from black radiate cast aluminum. The front wheel measures 19 inches in diameter and 2.5 inches in width. The rear wheel measures 16 inches in diameter and 5 inches in width. This setup supports traction and stability under acceleration and braking.
Braking System and Deceleration Control
The braking system includes dual front rotors and a single rear rotor. The front rotors measure 11.8 inches in diameter and use four-piston fixed calipers. The rear rotor measures 11.5 inches and uses a two-piston floating caliper.
Rotor thickness is 0.2 inches at the front and 0.23 inches at the rear. The rotors feature a split seven-spoke floating design, supporting heat dissipation and consistent braking performance.
An Anti-lock Braking System is included as standard equipment. This system prevents wheel lock during braking, maintaining traction and directional control.
Electrical System and Instrumentation
The electrical system uses a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp hours. The battery provides 310 cold cranking amps at zero degrees Fahrenheit.
Charging is managed by a three-phase, 48-amp system. Output includes 364 watts at 13 volts at 900 rpm and a maximum of 624 watts at 2,000 rpm. This ensures consistent electrical supply for all onboard systems.
Starting is handled by a 1.6 kilowatt electric starter motor with solenoid engagement. Lighting is fully LED, including the headlamp, taillamp, and turn signals. The headlamp includes a low beam, a high beam, and a signature position light.
Instrumentation is centered on a four-inch analog speedometer combined with a digital display. The display provides information including gear position, odometer, fuel level, ride modes, traction control status, ABS status, tire pressure monitoring, cruise control, clock, trip data, range, and tachometer readings.
A USB Type-C power outlet is included, delivering 5 volts at 2.4 amps for device charging.
Fuel Capacity and Efficiency Metrics
The motorcycle has a fuel capacity of 5 gallons, with a reserve capacity of 1 gallon indicated by a warning light. Fuel economy is estimated at 47 miles per gallon under combined city and highway conditions.
Oil capacity is 5 quarts with a filter, supporting lubrication requirements for the engine. Transmission capacity is 1 quart, and the primary chain case holds 1.25 quarts. These values support consistent operation and maintenance intervals.
Integrated Rider Safety Systems and Control Technologies
The 2026 Harley-Davidson® Low Rider® S includes multiple rider-assist systems designed to support stability and control. An anti-lock Braking System is standard, working in conjunction with the braking hardware to prevent wheel lock.
A traction control system is included, managing rear wheel slip during acceleration. The drag-torque Slip Control System reduces rear wheel instability during downshifting.
A tire pressure monitoring system provides continuous monitoring of tire pressure, alerting the rider to deviations from recommended levels.
Cornering-enhanced systems are also integrated. Cornering ABS adjusts braking performance based on lean angle. Cornering Traction Control modifies power delivery during cornering conditions. Cornering Drag-torque Slip Control further refines stability during deceleration while leaned.
