The 2026 Harley-Davidson® Street Glide® is a touring motorcycle designed with a focus on measurable performance, structural stability, and integrated rider systems. This model combines a large-displacement V-twin engine, a six-speed transmission, a steel frame, and a comprehensive electronic suite. The specifications reflect a platform intended for sustained highway operation, controlled handling, and consistent output across a wide operating range. The motorcycle also integrates infotainment, navigation, and rider-assistance systems into a unified interface, supported by a high-capacity electrical system and LED lighting architecture.
Milwaukee-Eight® 117 Engine Specifications and Output
The 2026 Harley-Davidson® Street Glide® uses the Milwaukee-Eight® 117 engine with a displacement of 117 cubic inches or 1,923 cubic centimeters. The engine operates with a pushrod-actuated overhead valve configuration and includes hydraulic self-adjusting lifters. Each cylinder contains four valves, supporting efficient airflow and combustion. The bore measures 4.075 inches, and the stroke measures 4.5 inches. The compression ratio is set at 10.3:1, which contributes to combustion efficiency and torque production.
Fuel delivery is handled by Electronic Sequential Port Fuel Injection. This system meters fuel precisely to each cylinder and supports consistent throttle response across varying conditions. The engine produces 130 foot-pounds of torque at 3,250 revolutions per minute and 105 horsepower at 4,600 revolutions per minute. These figures indicate a powerband that emphasizes low- and mid-range output rather than high-revving performance.
The lubrication system is a pressurized dry-sump design. This configuration separates oil storage from the crankcase, which helps maintain lubrication under extended operation and varying lean angles. The air intake system uses a washable fiberglass air cleaner. The exhaust system is a 2-1-2 dual configuration with tapered mufflers, designed to manage exhaust flow and maintain balanced performance.
Fuel capacity is 6 gallons, with a reserve warning at approximately 1 gallon. The estimated fuel economy is 44 miles per gallon. These figures indicate an extended riding range between refueling intervals when combined with the engine’s efficiency.
Transmission, Clutch, and Final Drive System
The drivetrain includes a chain-driven primary system with a 34/46 ratio and a belt-driven final drive with a 32/68 ratio. This combination is designed to transfer power efficiently while reducing maintenance requirements associated with fully chain-driven systems. The clutch is a mechanically actuated 10-plate wet clutch with assist and slip functionality. The assist feature reduces lever effort, and the slip function manages torque transfer during rapid downshifts to maintain rear-wheel stability.
The transmission is a 6-Speed Cruise Drive® unit. Gear ratios are configured to support both initial acceleration and sustained highway speeds. First gear has an overall ratio of 9.593, while sixth gear has an overall ratio of 2.875. Intermediate ratios are spaced to maintain consistent engine response during acceleration. This configuration supports reduced engine speed at higher road speeds and contributes to efficient long-distance operation.
Structural Frame and Chassis Composition
The frame is constructed from mild steel and uses a tubular design with a two-piece stamped and welded backbone. It incorporates cast and forged junctions and twin down-tubes. The rear frame section is bolt-on and includes forged fender supports. The swingarm is also constructed from mild steel with a two-piece drawn and welded design and forged junctions. These construction methods provide structural rigidity and support the motorcycle’s load capacity.
The wheelbase measures 64 inches. Steering geometry includes a rake of 26 degrees, a fork angle of 29.25 degrees, and a trail measurement of 6.7 inches. These dimensions contribute to directional stability and controlled steering response. The motorcycle has a static ground clearance of 5.5 inches. Lean angle capability is rated at 32 degrees on both the right and left sides.
The overall length of the motorcycle is 94.9 inches, with a width of 38.4 inches and a height of 53.1 inches. Seat height is 26.4 inches when laden and 28.1 inches when unladen. These measurements indicate a low seating position relative to overall size, supporting rider control during stops and low-speed maneuvers.
Suspension System and Ride Control
The front suspension uses a 49-millimeter Dual Bending Valve fork. This system is designed to manage compression and rebound characteristics under varying loads and road conditions. Front suspension travel measures 4.6 inches. The rear suspension consists of dual outboard emulsion shocks with preload adjustability and 3 inches of travel. Preload adjustment allows the rider to compensate for passenger weight or additional cargo.
Wheel, Tire, and Braking System Specifications
The 2026 Harley-Davidson® Street Glide® uses cast aluminum wheels with a 19-inch front wheel and an 18-inch rear wheel. The front wheel has a width of 3.5 inches, and the rear wheel has a width of 5 inches. The motorcycle is equipped with Dunlop® Harley-Davidson® Series bias blackwall tires. The front tire specification is 130/60B19 M/C 61H, and the rear tire specification is 180/55B18 M/C 80H.
The braking system includes dual floating front rotors with a diameter of 12.6 inches and a thickness of 0.18 inches. The front calipers are 32-millimeter four-piston fixed units mounted axially. The rear brake uses a single fixed rotor with a diameter of 11.8 inches and a thickness of 0.28 inches, paired with a single axially mounted caliper. This braking configuration provides sufficient stopping capability for a motorcycle with a running weight of 811 pounds.
An Anti-lock Braking System is standard. The system monitors wheel speed and modulates brake pressure to prevent wheel lock during braking events. Electronic Linked Braking distributes braking force between the front and rear wheels. The Traction Control System regulates rear-wheel slip during acceleration. Drag-torque Slip Control System manages engine braking effects during downshifting. Vehicle Hold Control maintains brake pressure when stopped on an incline. The Tire Pressure Monitoring System provides continuous tire pressure data.
Electrical System and Lighting Configuration
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 58-amp system capable of producing up to 754 watts at 13 volts. The starting system uses a 1.6-kilowatt electric starter with solenoid engagement.
Lighting components are fully LED. The headlamp, tail lamp, brake light, front signals, and rear turn signals all use LED technology. LED systems provide consistent illumination and reduced electrical load compared with traditional lighting systems.
A 15-watt USB-C power outlet is located in the media storage compartment. This outlet supports the charging of compatible devices during operation. The electrical system capacity supports infotainment, lighting, and accessory usage simultaneously.
Infotainment Interface and Connectivity Systems
The infotainment system operates on Skyline™ OS and is displayed on a 12.3-inch full-color TFT screen. The display integrates digital gauges and vehicle information into a single interface. This configuration centralizes speed, engine data, and system notifications.
Audio output is rated at 50 watts per channel. The system includes two 5.25-inch speakers mounted in the fairing. Radio functionality includes AM and FM. Media playback is supported through a USB connection. Bluetooth® connectivity supports hands-free mobile phone use and media streaming. Apple CarPlay® compatibility is available in both wired and wireless formats.
Navigation is integrated into the system and supports traffic and weather data through a Wi-Fi hotspot connection. The interface is designed to present navigation, media, and vehicle data simultaneously, reducing the need for separate devices.
Capacity, Weight, and Operational Measurements
The motorcycle has a fuel capacity of 6 gallons and an oil capacity of 5 quarts with a filter. Transmission capacity is 1 quart, and the primary chain case holds 1.1 quarts. Coolant capacity is 0.82 quarts. These fluid capacities support sustained operation and regular maintenance intervals.
The weight of the motorcycle is 774 pounds as shipped and 811 pounds in running order. The gross vehicle weight rating is 1,360 pounds. The front axle weight rating is 500 pounds, and the rear axle weight rating is 927 pounds. Luggage capacity measures 2.42 cubic feet, providing storage for touring requirements.
