The 2026 Harley-Davidson® Road Glide® 3 is engineered as a three-wheel touring platform that combines a large-displacement V-twin engine, integrated infotainment, and a chassis designed for stability and load management. This model incorporates a Milwaukee-Eight® VVT 117 engine, a 6-speed transmission with reverse, and a comprehensive suite of electronic rider assistance systems. The design emphasizes consistent power delivery, structured weight distribution, and integrated technology for navigation and connectivity.
Engine Architecture and Output Specifications
The 2026 Harley-Davidson® Road Glide® 3 uses a Milwaukee-Eight® VVT 117 engine with a displacement of 117 cubic inches, equivalent to 1,923 cubic centimeters. The engine operates with a pushrod valve system that includes overhead valves, hydraulic self-adjusting lifters, and four valves per cylinder. The bore measures 4.075 inches, and the stroke measures 4.5 inches, resulting in a compression ratio of 10.3:1. This configuration is designed to deliver consistent combustion efficiency and torque output across a wide operating range.
Harley-Davidson® rates the engine at 105 horsepower at 4,600 revolutions per minute. Maximum torque is listed at 129 foot-pounds at 3,250 revolutions per minute. The torque curve is positioned to support low to mid-range performance, which is necessary for a touring platform with a significant curb weight. The fuel system uses Electronic Sequential Port Fuel Injection, which provides controlled fuel delivery under varying load conditions. The lubrication system is pressurized and uses a dry-sump configuration, supporting engine longevity and stable oil circulation. Air intake is managed through a paper filter that is washable, and exhaust flow is routed through a 2-1-2 dual exhaust system designed for balanced output.
Drivetrain Configuration and Reverse Function Integration
The drivetrain of the 2026 Harley-Davidson® Road Glide® 3 is configured to manage both power transfer and operational control. Primary drive is handled by a chain system with a 34/46 ratio, while the final drive uses a belt system with a 30/70 ratio. The clutch is a mechanically actuated, ten-plate wet system with Assist and Slip functionality, which supports smoother engagement and reduces lever effort under load.
The transmission is a 6-speed Cruise Drive® unit that includes an integrated reverse function. The reverse is electrically actuated through handlebar-mounted controls, allowing controlled backward movement without manual pushing. This feature is essential for maneuvering a three-wheel platform with a running weight exceeding 1,100 pounds. Gear ratios are structured to provide a wide spread between first and sixth gears, supporting controlled acceleration and steady cruising at highway speeds. The drivetrain configuration is aligned with the model’s touring function, ensuring predictable engagement across different riding conditions.
Dimensional Structure and Load Capacity Engineering
The 2026 Harley-Davidson® Road Glide® 3 has an overall length of 103 inches, a width of 57.5 inches, and a height of 51.4 inches. The wheelbase measures 67.7 inches, contributing to directional stability and consistent tracking. Steering geometry includes a rake of 26 degrees, a fork angle of 32 degrees, and a trail measurement of 3.8 inches. These parameters influence steering response and front-end stability.
Seat height is measured at 26.5 inches in the laden condition and 27.9 inches in the unladen condition. Ground clearance is listed at 5.5 inches. The total weight in running order is 1,184 pounds, while the as-shipped weight is 1,146 pounds. The Gross Vehicle Weight Rating is 1,700 pounds, indicating the total allowable weight including rider, passenger, and cargo. Axle load ratings are 511 pounds for the front and 1,189 pounds for the rear.
Fuel capacity is 6 gallons, with an additional 1-gallon reserve indicated by a warning light. Oil capacity with filter is 5 quarts, and both the transmission and primary chain case each hold 1.1 quarts. Coolant capacity is 0.82 quarts. Luggage volume is specified at 2 cubic feet, supporting storage requirements for touring applications.
Chassis Composition and Suspension Characteristics
The chassis is constructed using a mild steel frame with a square-section backbone and twin downtubes. This structure is designed to provide rigidity while accommodating the trike configuration. The swingarm is made from permanent mold cast aluminum, contributing to strength and reduced weight in the rear assembly.
Front suspension consists of a 49-millimeter dual bending valve fork. Rear suspension uses a hand-adjustable emulsion shock system, allowing adjustment based on load conditions. Suspension travel is 4.6 inches at the front and 3.5 inches at the rear.
The trike layout distributes weight across one front wheel and two rear wheels, requiring suspension tuning that balances ride comfort with structural control. The selected components support consistent damping and load handling, particularly during long-distance travel and varying road surfaces.
Wheel Design, Tire Specifications, and Brake System Details
The 2026 Harley-Davidson® Road Glide® 3 uses cast aluminum wheels with a gloss black and machined finish in a five-spoke configuration. The front wheel has a diameter of 19 inches and a width of 3.5 inches. The rear wheels each measure 18 inches in diameter and 7 inches in width. Tire selection includes a Dunlop® Harley-Davidson® Series front bias tire and rear radial tires. The front tire specification is MT 130/60B19 M/C 61H, while the rear tire specification is P215/45R18 83T.
The braking system includes dual floating rotors at the front and a fixed rotor at the rear. Front calipers are 32-millimeter four-piston fixed units, while the rear uses a floating 36-millimeter piston with an integrated park brake. Rotor diameter is 11.8 inches at both front and rear. Rotor thickness is 0.197 inches at the front and 0.276 inches at the rear. The system includes an Anti-lock Braking System as standard equipment.
Electrical System and Integrated Technology Interface
The electrical system includes a sealed, maintenance-free 12-volt battery rated at 28 amp-hours and 405 cold cranking amps. Charging is handled by a three-phase, 48-amp system capable of delivering 600 watts at 13 volts and 2,000 revolutions per minute, with a maximum output of 625 watts. Starting is managed by a 1.6-kilowatt electric starter with solenoid engagement.
Lighting components use LED technology for the headlamp, tail, and stop lights, and turn signals. This configuration supports consistent illumination and reduced electrical load. The instrument system uses digital gauges integrated into the main display, eliminating the need for separate analog components.
The infotainment system operates on Skyline™ OS and uses a 12.3-inch full-color TFT display. Audio output is delivered through two 5.25-inch speakers with 50 watts per channel. Standard radio functions include AM and FM, and the system supports USB media input through a USB-C interface located in the inner fairing storage compartment.
Connectivity features include Bluetooth® support for mobile phone integration, media playback, and headset pairing. Apple CarPlay® is supported in both wired and wireless configurations. Navigation is embedded within the system and provides traffic and weather information through a Wi-Fi hotspot connection. Additional system functions include vehicle information display with air temperature, oil pressure, and engine idle temperature management system data.
Rider Assistance Systems and Control Technologies
The 2026 Harley-Davidson® Road Glide® 3 includes multiple electronic rider assistance systems designed to support control under varying conditions. Standard features include Anti-lock Braking System, Electronic Linked Braking, Traction Control System, and Drag-torque Slip Control System. These systems manage braking force distribution, traction limits, and engine braking behavior.
Cornering-specific enhancements are also included. These consist of Cornering Enhanced Anti-lock Braking System, Cornering Enhanced Electronic Linked Braking, Cornering Enhanced Traction Control System, and Cornering Drag-Torque Slip Control System. These systems adjust intervention based on lean angle and dynamic conditions, improving control during directional changes.
A Tire Pressure Monitoring System is included, providing continuous feedback on tire inflation levels. Electric reverse control is integrated into the handlebar controls, allowing controlled backward movement. These features contribute to operational stability and improved rider awareness during both low-speed and higher-speed operation.
