The 2026 Harley-Davidson® Street Bob® is designed with a focus on mechanical efficiency, structural integrity, and essential rider-focused systems. This model integrates a high-displacement V-twin engine, a Softail®-based frame, and a selection of electronic rider aids that enhance operational control without adding unnecessary complexity. Its design emphasizes balanced proportions, consistent power delivery, and straightforward instrumentation.
Engine Configuration and Output Characteristics
The 2026 Harley-Davidson® Street Bob® is equipped with the Milwaukee-Eight® 117 Classic engine, a V-twin configuration with a displacement of 117 cubic inches or 1,923 cubic centimeters. The engine uses a bore of 4.075 inches and a stroke of 4.5 inches, supporting a compression ratio of 10.3:1. This configuration is designed to deliver consistent combustion efficiency and steady torque output.
The valve train consists of pushrod-operated overhead valves with hydraulic, self-adjusting lifters. Each cylinder contains four valves, which improves airflow and combustion efficiency. The engine produces 98 horsepower at 4,600 revolutions per minute and generates 120 lb-ft of torque at 2,500 revolutions per minute. This torque delivery at low engine speed supports controlled acceleration and a reduced need for frequent gear changes.
Fuel delivery is managed through Electronic Sequential Port Fuel Injection. This system meters fuel precisely based on engine load and operating conditions. The air intake system includes a 9-inch round air cleaner with a center bolt cover and washable fiberglass filter media. Exhaust flow is handled through a 2-into-1 system with a catalyst integrated into the header.
The lubrication system is pressurized and utilizes a dry-sump configuration with an integrated oil cooler. This design maintains stable oil temperatures and ensures consistent lubrication during extended operation.
Transmission and Driveline Engineering
Power from the engine is transferred through a chain-driven primary system with a 34 to 46 ratio. The final drive uses a belt system with a 32 to 66 ratio. This configuration reduces maintenance requirements while maintaining efficient power transfer.
The motorcycle is equipped with a 6-speed Cruise Drive® transmission. Gear ratios are structured to provide a wide operational range, from a 9.311 ratio in first gear to 2.79 in sixth gear. This range allows controlled low-speed operation and reduced engine speed during highway riding.
The clutch system is a mechanical 10-plate wet clutch with assist and conventional operation. This configuration reduces lever effort and improves engagement consistency. The system supports smoother transitions between gears and maintains stability during acceleration and deceleration.
Frame Construction and Structural Design
The 2026 Harley-Davidson® Street Bob® utilizes a mild steel tubular frame with a rectangular backbone. The frame incorporates stamped, cast, and forged junctions that are MIG welded for structural consistency. Aluminum forged fender supports contribute to weight management without compromising strength.
The swingarm is constructed from mild steel tubular sections and includes a stamped cross-member and forged axle junctions. The design supports stability under load and maintains alignment during acceleration.
The overall geometry includes a rake angle of 30 degrees and a trail measurement of 6.2 inches. The wheelbase measures 64.2 inches, contributing to stable handling and predictable steering response. These specifications are designed to maintain directional stability while allowing controlled maneuverability.
Suspension Systems and Ride Control
The front suspension consists of a 49 mm telescopic fork with dual-bending valve technology. This system includes aluminum fork triple clamps and dual-rate springs. The configuration improves damping characteristics and provides controlled response over uneven surfaces.
The rear suspension uses a hidden coil-over monoshock with a 43 mm stroke. The system includes cam-style preload adjustment, allowing the rider to modify suspension settings based on load and riding preference.
Front suspension travel measures 5 inches, while rear travel measures 3.4 inches. This combination supports a balance between comfort and handling precision.
Dimensions, Weight Distribution, and Ground Clearance
The overall length of the 2026 Harley-Davidson® Street Bob® is 91.3 inches, with a width of 36.4 inches and a height of 45.7 inches. The seat height is 25.8 inches when laden and 26.8 inches when unladen. These measurements contribute to a low center of gravity and improved rider accessibility.
Static ground clearance is measured at 4.9 inches. This clearance supports moderate lean angles while maintaining structural protection. The motorcycle achieves a lean angle of 28.5 degrees on both the left and right sides.
The weight of the motorcycle is 622 pounds as shipped and 646 pounds in running order. The gross vehicle weight rating is 1,160 pounds, with a front axle rating of 450 pounds and a rear axle rating of 730 pounds. These figures support load distribution and structural capacity.
Fuel capacity is 3.5 gallons, with a reserve capacity of 1 gallon. Oil capacity is 5 quarts with a filter, and the transmission holds 1 quart. The primary chain case capacity is 1.25 quarts.
Wheels, Tires, and Braking Components
The 2026 Harley-Davidson® Street Bob® is equipped with Dunlop® Harley-Davidson® Series bias blackwall tires. The front tire specification is 100/90B19, and the rear tire specification is 150/80B16. These tires are designed to provide consistent traction and durability.
The front wheel measures 19 inches in diameter with a width of 2.5 inches, while the rear wheel measures 16 inches in diameter with a width of 3 inches. Both wheels are constructed from black Annihilator cast aluminum.
Braking is managed by a 4-piston fixed front caliper and a 2-piston floating rear caliper. The front brake rotor measures 11.8 inches in diameter with a thickness of 0.2 inches. The rear rotor measures 11.5 inches in diameter with a thickness of 0.23 inches.
An anti-lock Braking System is included as standard equipment. This system prevents wheel lock during braking and maintains directional control.
Electrical System and Instrumentation
The electrical system includes a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp-hours. The charging system is a three-phase 48-amp configuration, delivering up to 624 watts of maximum power at 2,000 revolutions per minute.
The starting system uses a 1.6 kW electric starter motor with solenoid shift engagement. Lighting is fully LED-based, including the headlamp, taillamp, and turn signals. This configuration improves visibility and reduces electrical load.
Instrumentation is centered around a 4-inch analog speedometer with an integrated digital display. The display provides information such as gear position, odometer, fuel level, ride modes, traction control status, ABS status, tire pressure monitoring, cruise control, trip data, and tachometer readings.
A USB-C power outlet is included, providing 5 volts at 2.4 amps for device charging.
Technology Systems and Functional Integration
The 2026 Harley-Davidson® Street Bob® maintains a simplified technology approach. It does not include an integrated infotainment system, onboard navigation, or Bluetooth® connectivity. This design reduces system complexity and focuses on essential operational data.
Rider Safety Systems and Control Enhancements
The 2026 Harley-Davidson® Street Bob® includes a range of rider safety systems designed to improve stability and control. An anti-lock Braking System is included as standard. The Traction Control System monitors wheel speed and adjusts power delivery to maintain traction.
The Drag-torque Slip Control System reduces rear-wheel slip during deceleration by managing engine braking. The Tire Pressure Monitoring System provides real-time tire pressure data to support safe operation.
Cornering-enhanced systems are also included. Cornering Anti-lock Braking System adjusts braking performance based on lean angle. Cornering Traction Control modifies power delivery during turns. The Cornering Drag-torque Slip Control System manages deceleration forces during cornering.
These systems work together to maintain stability and control across a range of riding conditions.
Fuel Efficiency and Operational Range
The 2026 Harley-Davidson® Street Bob® achieves an estimated fuel economy of 47 miles per gallon under combined city and highway conditions. This efficiency supports extended riding intervals between refueling..
