The 2026 Harley-Davidson® Street Glide® 3 Limited is engineered as a three-wheel touring motorcycle designed to combine stable handling, substantial engine output, integrated technology, and long-distance functionality. Its technical configuration reflects an emphasis on controlled performance, touring comfort, and system integration rather than stylistic complexity. The model uses a purpose-built chassis layout, a high-displacement V-twin powertrain, and electronically managed rider-assistance features to support predictable operation across varying road conditions.
The dimensions and structural specifications define its touring focus. The motorcycle measures approximately 105.7 inches in length, with an overall width of 57.3 inches. A laden seat height of 27.3 inches contributes to accessibility and stable rider positioning. The wheelbase extends to 67.7 inches, supporting straight-line stability and smooth highway tracking. Ground clearance measures 5.1 inches, supporting controlled cornering while maintaining adequate clearance for touring routes. The geometry includes a 26-degree rake and a 3.8-inch trail, all configured to enhance directional stability and steering predictability.
Engine Configuration and Output Characteristics
The 2026 Harley-Davidson® Street Glide® 3 Limited uses the Milwaukee-Eight® VVT 117 engine, designed to deliver consistent torque across low and mid-range rpm. The engine displacement is 117 cubic inches. This setup employs pushrod-operated overhead valves with hydraulic self-adjusting lifters and four valves per cylinder. These components reduce maintenance complexity while supporting efficient valve operation during extended riding intervals.
The bore measures 4.075 inches and the stroke measures 4.5 inches, creating a long-stroke profile suited for torque generation rather than high-rev operation. Compression ratio is rated at 10.3:1, balancing performance output with durability requirements. Fuel delivery is managed by Electronic Sequential Port Fuel Injection, which maintains consistent fueling across varying riding conditions and load demands. The lubrication system is pressurized and dry-sump, assisting in oil circulation stability during prolonged operation.
Engine performance specifications indicate approximately 129 ft-lb of torque produced at 3,250 rpm and a peak output of around 105 horsepower at 4,600 rpm. These figures emphasize usable thrust during acceleration and sustained cruising. The air cleaner uses a synthetic felt washable design to maintain airflow while allowing serviceability. Exhaust flow is routed through a 2-1-2 dual exhaust system that supports balanced airflow and heat management.
Transmission and Drivetrain Engineering
Power delivery passes through a mechanically actuated 10-plate wet Assist and Slip clutch designed to reduce lever effort and control drivetrain shock during downshifting. The transmission is a 6-speed that includes reverse capability. Reverse operation is electrically actuated and controlled from handlebar-mounted controls, improving low-speed maneuvering during parking and tight-space adjustments.
Primary power transfer uses a chain drive with a 34/46 ratio. This combination reduces mechanical noise and maintenance requirements while maintaining smooth torque delivery to the rear drivetrain system. Gear ratios are configured to provide strong initial acceleration and relaxed cruising characteristics. The first gear ratio is 10.534, progressively reducing through second and third gears at 7.302 and 5.423, then continuing through higher gears to a sixth-gear ratio of 3.0, which supports efficient highway travel.
Chassis Design and Structural Components
The frame construction uses mild steel with a square-section backbone and twin downtubes. This design supports structural rigidity and consistent load distribution for a three-wheel touring platform. A permanent mold cast aluminum swingarm contributes to reduced unsprung weight while maintaining durability under heavy touring loads.
Front suspension utilizes a dual bending valve fork, designed to absorb road irregularities and maintain front-end composure. Rear suspension includes hand-adjustable emulsion shocks, allowing preload adjustments based on rider and cargo requirements.
The wheel configuration includes cast aluminum 10-spoke wheels finished in gloss black with machined detailing. The front wheel measures 19 inches in diameter and 3.5 inches in width. Rear wheels measure 18 inches in diameter and 7 inches in width. Tire specifications include a 130/60B19 front tire and a P215/45R18 rear tire configuration. This setup supports grip stability, predictable steering response, and load-bearing performance appropriate for touring applications.
Braking Systems and Control Integration
The braking system combines mechanical hardware with electronic control systems to maintain stopping consistency. Front brakes feature 4-piston fixed calipers paired with dual floating front rotors. The rear braking system uses a floating integrated park brake.
Anti-Lock Braking System functionality is included as standard equipment. Electronic Linked Braking distributes braking force between front and rear systems to improve balance during deceleration. Additional support systems include the Traction Control System and Drag-torque Slip Control System. These systems monitor wheel behavior and regulate power or braking input when traction levels change. Cornering-enhanced systems extend these functions by adjusting control parameters when leaning or turning conditions are detected. Tire Pressure Monitoring System integration allows riders to monitor tire inflation for optimal control and efficiency.
Electrical Architecture and Functional Equipment
Electrical capacity is supported by a sealed, maintenance-free 12-volt battery rated at 28 amp-hours with a 405 CCA specification. Charging performance is managed by a three-phase 48-amp system capable of producing up to 625 watts of maximum output. This capacity supports infotainment components, lighting systems, and accessory charging without compromising operational stability.
Starting operation relies on a 1.6 kW electric starter motor with solenoid shift engagement. Lighting systems use LED technology for the headlamp, tail lamp, turn signals, and integrated fog lamps. LED lighting enhances visibility and reduces energy consumption compared to conventional lighting systems. Digital gauges are integrated directly into the display interface, reducing the need for separate instrument clusters.
A USB-C power outlet rated at 15 watts is positioned in the media storage compartment to support device charging during travel. Electric reverse integration also depends on the electrical architecture, allowing controlled rearward movement through handlebar-mounted controls.
Infotainment Platform and Connectivity Features
The infotainment system operates on Skyline™ OS and is displayed through a 12.3-inch full-color TFT screen. The interface combines navigation, vehicle information, communication, and audio controls into a single centralized system. Display visibility and digital gauge integration simplify information access while riding.
Audio output is delivered through four speakers powered at 50 watts per channel. Speaker configuration includes two fairing-mounted speakers and two Tour-Pak® speakers, designed to maintain clarity during highway speeds. AM and FM functionality are provided as standard, while Bluetooth® support enables phone and media connectivity.
Phone integration supports Apple CarPlay® through wired or wireless connections. USB-C and MTP compatibility allow connection with multiple smartphone types when proper adapters are used. Embedded navigation capability is included, supporting traffic and weather awareness through connected services. Vehicle information displayed through the system includes air temperature, oil pressure, and engine management indicators. Intercom functionality is available with compatible rider and passenger headsets.
Capacity, Efficiency, and Operating Specifications
Fuel capacity is rated at 6 gallons, with a reserve warning level equivalent to approximately 1 gallon. Fuel economy is estimated at 39 mpg under city and highway combined testing conditions. Oil capacity with filter measures 5 quarts, while transmission capacity is 1.22 quarts. Primary chain case capacity measures 1.1 quarts, and coolant capacity is approximately 0.82 quarts.
Weight specifications indicate approximately 1,213 pounds as shipped and about 1,250 pounds in running order. Gross vehicle weight rating is listed at 1,700 pounds, with front and rear axle ratings configured to support rider, passenger, and cargo loads. Luggage storage volume totals approximately 7.1 cubic feet, supporting extended touring requirements without modifications.
