The 2026 Harley-Davidson® Street Glide® 3 Limited is a three-wheel touring model designed with a focus on mechanical consistency, integrated electronics, and long-distance capability. This model combines a large-displacement Milwaukee-Eight® VVT 117 engine, a 6-speed transmission with reverse, and a chassis engineered to support increased weight and cargo demands. The design prioritizes stability, control, and sustained performance across extended riding conditions.
Dimensional Structure and Touring Capacity
The 2026 Harley-Davidson® Street Glide® 3 Limited measures 105.7 inches in length, 57.3 inches in width, and 56.5 inches in height. These dimensions establish a wide and stable platform that accommodates the three-wheel layout. The wheelbase extends to 67.7 inches, contributing to directional stability and consistent weight distribution. The rake angle is set at 26 degrees, with a fork angle of 32 degrees and a trail measurement of 3.8 inches. These values define the steering geometry that supports controlled input and predictable tracking.
Seat height measures 27.3 inches in a laden condition and 28.9 inches when unladen. Static ground clearance is listed at 5.1 inches. These measurements support accessibility while maintaining adequate clearance for touring conditions. The model uses Dunlop® Harley-Davidson® Series tires, with a front specification of 130/60B19 M/C 61H and a rear specification of P215/45R18 83T. The tire configuration reflects the requirement for traction and load support across a three-wheel system.
Fuel capacity is rated at 6 gallons, with a reserve capacity of 1 gallon. Oil capacity is 5 quarts with a filter, and the transmission holds 1.22 quarts. The primary chain case capacity is 1.1 quarts, and the coolant capacity is 0.82 quarts. Weight as shipped is 1,213 pounds, while the running order weight is 1,250 pounds. The gross vehicle weight rating is 1,700 pounds, with a front axle rating of 511 pounds and a rear axle rating of 1,189 pounds. Luggage volume is measured at 7.1 cubic feet, supporting extended travel requirements.
Engine Configuration and Output Metrics
The 2026 Harley-Davidson® Street Glide® 3 Limited is powered by the Milwaukee-Eight® VVT 117 engine. This engine uses a displacement of 117 cubic inches, equivalent to 1,923 cubic centimeters. The bore measures 4.075 inches, and the stroke measures 4.5 inches. The compression ratio is set at 10.3:1. The engine uses pushrod-operated overhead valves with hydraulic self-adjusting lifters and four valves per cylinder.
Fuel delivery is managed through Electronic Sequential Port Fuel Injection. The air intake system uses a synthetic felt washable air cleaner. The exhaust system follows a 2-1-2 dual configuration. Lubrication is handled through a pressurized dry-sump system. These systems are designed to maintain consistent engine operation during extended riding periods and under varying load conditions.
The engine produces 129 foot-pounds of torque at 3,250 rpm. Power output is rated at 105 horsepower at 4,600 rpm. These figures indicate a focus on low to mid-range performance, which supports steady acceleration and controlled power delivery during touring applications. Fuel economy is estimated at 39 miles per gallon under combined city and highway conditions.
Transmission and Drivetrain Mechanics
The drivetrain system uses a chain primary drive with a 34/46 ratio and a belt final drive with a 30/70 ratio. The clutch is a mechanically actuated 10-plate wet system with Assist and Slip functionality. This design supports smoother engagement and reduced lever effort during operation.
The transmission is a 6-speed Cruise Drive® unit that includes an integrated reverse function. The reverse is electrically actuated using handlebar-mounted controls. This system supports controlled maneuvering in confined spaces and when repositioning the vehicle at low speeds.
Gear ratios are defined as 10.534 in first gear, 7.302 in second gear, 5.423 in third gear, 4.392 in fourth gear, 3.742 in fifth gear, and 3.000 in sixth gear. These ratios provide a progression that supports acceleration from a standstill while maintaining reduced engine speed at higher cruising speeds. The drivetrain configuration is designed to balance torque delivery with fuel efficiency and mechanical stability.
Chassis Construction and Suspension Design
The chassis uses a mild steel frame with a square-section backbone and twin downtubes. The swingarm is constructed from permanent mold cast aluminum. This combination provides structural rigidity and supports the overall weight of the vehicle.
Front suspension consists of a 49 mm dual bending valve fork with 4.6 inches of travel. Rear suspension uses a hand-adjustable emulsion system with 3.5 inches of travel. The rear system allows for manual adjustment to accommodate load variations. Suspension components are designed to maintain contact with the road surface while absorbing irregularities encountered during travel.
The front wheel measures 19 inches in diameter and 3.5 inches in width. The rear wheels measure 18 inches in diameter and 7 inches in width. All wheels use a gloss black and machined 10-spoke cast aluminum design. These specifications support structural strength and consistent load handling across the three-wheel platform.
Braking Systems and Safety Integration
The braking system includes dual front floating rotors and a fixed rear rotor. Front calipers are 32 mm four-piston fixed units, while the rear uses a 36 mm floating piston with an integrated park brake. Both front and rear rotors measure 11.8 inches in diameter. The system is designed to deliver consistent braking force across all wheels.
An anti-lock braking system is included as standard equipment. Electronic Linked Braking is also included, distributing braking force between front and rear systems. The Traction Control System manages wheel slip during acceleration. The Drag-torque Slip Control System reduces rear wheel instability during deceleration.
The model includes a Tire Pressure Monitoring System that provides ongoing tire pressure data. Cornering-enhanced systems include cornering ABS, cornering electronic linked braking, cornering traction control, and cornering drag-torque slip control. These systems adjust performance parameters based on lean and directional input, supporting controlled operation during turns.
Electrical System and Functional Equipment
The electrical system uses 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, producing 600 watts at 13 volts and 2,000 rpm, with a maximum output of 625 watts. Starting is managed by a 1.6 kW electric system with a solenoid shift starter motor.
Lighting components include an LED headlamp, LED tail and stop lamps, LED front signal lights, and LED rear turn signals. LED fog lamps are integrated into the lower fairings. These components provide consistent illumination and visibility.
An electric power outlet is included in the form of a 15-watt USB-C port located in the media storage compartment. This supports charging for compatible devices during operation. The model also includes an electric reverse system integrated into the control layout.
Infotainment System and Connectivity Features
The infotainment system operates on Skyline™ OS and uses a 12.3-inch full-color TFT display. This display integrates digital gauges and vehicle information, including air temperature and oil pressure. The system centralizes operational data within a single interface.
Audio output is delivered through four speakers, including two 6.5-inch fairing speakers and two 6.5-inch Tour-Pak® speakers. Each channel provides 50 watts of output. AM and FM radio are standard. Media playback is supported through USB connectivity, including MP3 and flash drive formats.
Bluetooth® connectivity supports hands-free mobile phone operation, media playback, and headset integration. Apple CarPlay® is supported through both wireless and wired connections. Navigation is available through an embedded GPS system. This system integrates route guidance with traffic and weather data through a Wi-Fi connection.
