The 2026 Harley-Davidson® Street Glide® is designed as a touring motorcycle that integrates engine performance, chassis stability, and electronic systems into a single platform. The model uses the FLHX configuration and incorporates a Milwaukee-Eight® 117 engine, a six-speed transmission, and a reinforced frame structure. The motorcycle is engineered to maintain consistent output across long distances, with specifications that support sustained highway operation and controlled handling. Its configuration reflects a focus on mechanical reliability, structured geometry, and integrated rider assistance systems.
Engine Configuration and Output Characteristics
The Milwaukee-Eight® 117 engine features a displacement of 117 cubic inches, equivalent to 1,923 cubic centimeters. The engine uses a pushrod-operated overhead valve design with hydraulic self-adjusting lifters. Each cylinder contains four valves, supporting airflow efficiency and combustion stability.
The bore measures 4.075 inches, while the stroke is 4.5 inches. This long-stroke configuration supports torque production at lower engine speeds. The compression ratio is set at 10.3 to 1, contributing to controlled combustion and thermal efficiency.
The engine produces 105 horsepower at 4,600 revolutions per minute. Torque output reaches 130 foot-pounds at 3,250 revolutions per minute. This torque delivery supports acceleration from low speeds and maintains consistent pulling force during highway riding.
Fuel delivery is managed through Electronic Sequential Port Fuel Injection. This system meters fuel based on operating conditions, supporting consistent engine response. The lubrication system uses a pressurized dry-sump configuration, which separates oil storage from the crankcase and maintains lubrication under varying riding conditions.
Air intake is handled through a fiberglass washable air cleaner. Exhaust flow is routed through a 2-1-2 dual exhaust system with tapered mufflers. This configuration supports exhaust gas flow and maintains consistent back pressure.
Transmission and Drivetrain Structure
The drivetrain integrates a 6-speed Cruise Drive® transmission. Gear ratios are spaced to support both low-speed maneuverability and high-speed cruising efficiency. The first gear ratio is 9.593, while the sixth gear ratio is 2.875. Intermediate ratios provide gradual transitions between gears.
The primary drive uses a chain with a 34 to 46 ratio. The final drive uses a belt system with a 32 to 68 ratio. This configuration balances durability with reduced maintenance requirements.
The clutch system consists of a mechanically actuated 10-plate wet clutch. It includes Assist and Slip functionality. Assist reduces the force required at the lever, while Slip limits rear wheel instability during downshifting.
Frame Design and Structural Integrity
The frame of the 2026 Harley-Davidson® Street Glide® uses a mild steel tubular structure with a two-piece stamped and welded backbone. Cast and forged junctions reinforce high-stress areas. The frame includes twin downtubes and a bolt-on rear section with forged fender supports. All structural joints are MIG welded.
The swingarm is constructed from mild steel using a two-piece drawn and welded design. Forged junctions enhance rigidity and alignment. This structure supports consistent rear wheel tracking under load.
The wheelbase measures 64 inches, contributing to straight-line stability. The rake angle is 26 degrees, and the fork angle is 29.25 degrees. The trail measures 6.7 inches, supporting controlled steering response.
Suspension Geometry and Ride Control
The front suspension uses a 49-millimeter Dual Bending Valve fork. This design improves damping control by managing oil flow during compression and rebound cycles. The fork supports consistent front-end feedback under braking and cornering.
The rear suspension consists of dual outboard emulsion shocks. These shocks provide 3 inches of travel and include preload adjustability. This allows adjustment based on rider weight and cargo load.
Front suspension travel measures 4.6 inches. Rear suspension travel measures 3 inches. These values balance comfort with handling precision.
Wheel and Tire Specifications
The 2026 Harley-Davidson® Street Glide® uses cast aluminum wheels. The front wheel has a diameter of 19 inches and a width of 3.5 inches. The rear wheel has a diameter of 18 inches and a width of 5 inches.
The tires are Dunlop® Harley-Davidson® Series bias blackwall. The front tire specification is 130/60 B19 with a load and speed rating of 61H. The rear tire specification is 180/55 B18 with a rating of 80H.
These tire dimensions support traction and stability across different riding conditions. The combination of wheel size and tire profile contributes to consistent handling characteristics.
Braking System and Control Mechanisms
The braking system uses dual front rotors with a diameter of 12.6 inches. Each rotor is paired with a 4-piston fixed caliper mounted axially. The rear brake uses a single rotor with a diameter of 11.8 inches and a fixed caliper.
The front rotor thickness measures 0.18 inches, while the rear rotor thickness measures 0.28 inches. This configuration supports heat dissipation and consistent braking performance.
Anti-lock Braking System is included as standard equipment. Electronic Linked Braking distributes braking force between the front and rear wheels. Traction Control System manages wheel slip during acceleration.
The drag-torque slip control system reduces rear wheel instability during deceleration. Vehicle Hold Control maintains brake pressure when the motorcycle is stopped on an incline. The Tire Pressure Monitoring System provides continuous feedback on tire pressure levels.
Cornering-enhanced systems include the Cornering Anti-lock Braking System, Cornering Electronic Linked Braking, Cornering Traction Control System, and Cornering Drag-torque Slip Control System. These systems adjust braking and traction inputs based on lean angle.
Electrical System and Power Management
The electrical system uses a sealed 12-volt battery with a capacity of 28 amp-hours and 405 cold-cranking amps. The charging system is a three-phase 58-amp unit capable of producing up to 754 watts at 13 volts.
The starting system uses a 1.6-kilowatt electric starter with a solenoid shift mechanism. This supports reliable engine starting under varying conditions.
Lighting components are fully LED. The headlamp, tail and stop lamp, and turn signals all use LED technology. This improves visibility and reduces power consumption.
A USB-C power outlet rated at 15 watts is located in the media storage compartment. This allows charging of compatible electronic devices during operation.
Infotainment System and Digital Interface
The 2026 Harley-Davidson® Street Glide® uses the Skyline™ OS infotainment system. The interface is displayed on a 12.3-inch full-color TFT screen. Digital gauges are integrated into the display, providing vehicle data and system information.
Audio output is delivered through two fairing-mounted speakers, each measuring 5.25 inches. The system provides 50 watts per channel, supporting audio clarity at varying speeds.
The infotainment system includes AM and FM radio functionality. Media playback is supported through USB connection. Bluetooth® connectivity allows integration with mobile devices for phone and media functions.
Apple CarPlay® compatibility is available through both wireless and wired connections. The system also supports navigation functions and displays vehicle information such as air temperature and oil pressure.
Voice communication is supported through headset systems with VOX capability when compatible equipment is used. Text-to-speech functionality is included for system prompts and navigation guidance.
