The 2026 Harley-Davidson® Street Bob® measures 91.3 inches in overall length, 36.4 inches in overall width, and 45.7 inches in overall height. The laden seat height is 25.8 inches, while the unladen seat height measures 26.8 inches. Static ground clearance is rated at 4.9 inches. The motorcycle uses a 64.2-inch wheelbase with a 30-degree rake and 6.2 inches of trail. These chassis dimensions support directional stability while maintaining controlled low-speed maneuverability.
Milwaukee-Eight® 117 Engine Configuration
The 2026 Harley-Davidson® Street Bob® uses the Milwaukee-Eight® 117 Classic engine. This engine features pushrod-operated overhead valves with hydraulic self-adjusting lifters and four valves per cylinder. Bore measures 4.075 inches, and stroke measures 4.5 inches. Total displacement is 117 cubic inches, equivalent to 1,923 cc. The compression ratio is rated at 10.3:1.
Electronic Sequential Port Fuel Injection manages fuel delivery and throttle response. The fuel system is calibrated for operation with recommended 91-octane fuel or higher. The engine uses a 9-inch round air cleaner with a center bolt cover and washable fiberglass filter media. Exhaust routing uses a 2-into-1 system with a catalyst integrated into the header assembly.
The lubrication system uses a pressurized dry-sump configuration with an oil cooler. This system separates oil storage from the crankcase and supports stable lubrication performance during extended riding conditions. Engine output is rated at 98 horsepower at 4,600 rpm and 120 ft-lb of torque at 2,500 rpm. The torque characteristics emphasize low-rpm acceleration and sustained roll-on response during highway operation.
Transmission and Drivetrain Specifications
The 2026 Harley-Davidson® Street Bob® uses a 6-Speed Cruise Drive® transmission combined with a chain-driven primary and belt-driven final drive system. Primary drive ratio is 34/46, while the final drive ratio is 32/66. The transmission integrates a mechanical, 10-plate wet clutch with assist and conventional operation.
Gear ratios are configured to balance launch performance, mid-range acceleration, and highway cruising efficiency. First gear ratio is 9.311 overall. Second gear ratio is 6.454. The third gear ratio is 4.793. Fourth gear ratio is 3.882. Fifth gear ratio is 3.307. The sixth gear ratio is 2.79.
The belt final drive reduces drivetrain maintenance requirements while supporting smooth power transfer characteristics. The transmission layout also supports lower engine rpm during highway speeds, contributing to reduced vibration and controlled throttle response during long-distance riding.
Softail® Chassis and Structural Engineering
The frame uses mild steel tubular construction with a rectangular-section backbone. The chassis incorporates stamped, cast, and forged junctions joined through MIG welding techniques. Aluminum forged fender supports contribute to structural rigidity while reducing component weight.
The swingarm uses mild steel tubular sections with a stamped cross-member and forged axle junctions. The assembly includes MIG-welded construction and a removable belt spacer. This structure supports rear-wheel alignment stability while maintaining compatibility with the belt-drive system.
The motorcycle uses a wheelbase of 64.2 inches, supporting directional stability during highway riding. Steering geometry includes a 30-degree rake and a matching fork angle. Trail measurement is rated at 6.2 inches. Combined chassis geometry contributes to stable corner entry and controlled steering response during low-speed urban operation.
Gross Vehicle Weight Rating is 1,160 pounds. Gross Axle Weight Rating is 450 pounds for the front axle and 730 pounds for the rear axle. Weight as shipped is 622 pounds, while the running order weight is rated at 646 pounds.
Front and Rear Suspension Operation
Front suspension uses a dual-bending valve 49 mm telescopic fork system with aluminum fork triple clamps and dual-rate springs. Fork gaiter covers protect exposed fork surfaces from debris accumulation. Front suspension travel measures 5 inches.
Rear suspension uses a hidden free-piston coil-over monoshock with 43 mm stroke. Preload adjustment is controlled through a cam-style mechanism. Rear suspension travel measures 3.4 inches. The hidden monoshock layout preserves the Softail® profile while maintaining rear suspension movement and damping performance.
The suspension system is configured to balance low-speed ride comfort with chassis stability during acceleration and braking transitions. Front and rear suspension geometry also contributes to lean-angle capability and tire contact consistency during cornering operations.
Wheel Construction and Tire Dimensions
The 2026 Harley-Davidson® Street Bob® uses black Annihilator cast aluminum wheels. The front wheel diameter measures 19 inches with a width of 2.5 inches. Rear wheel diameter measures 16 inches with a width of 3 inches. Optional painted aluminum tubeless laced wheels are also listed for selected markets and configurations.
Tire equipment includes Dunlop® Harley-Davidson® Series bias blackwall tires. Front tire specification is 100/90B19 57H BW using the D401F model designation. Rear tire specification is 150/80B16 77H BW using the D401T model designation.
Brake System and Lean-Angle Control
The front brake system uses a 4-piston fixed caliper paired with an 11.8-inch solid uniform expansion rotor. Rotor thickness measures 0.2 inches. The rear brake system uses a 2-piston floating caliper with an 11.5-inch rotor measuring 0.23 inches thick.
An anti-lock braking system is included as standard equipment. The system monitors wheel speed and assists with braking control during reduced-traction conditions. The 2026 Harley-Davidson® Street Bob® also integrates Cornering Enhanced Anti-lock Brake System technology. This system accounts for lean-angle conditions while managing brake-force modulation during cornering operation.
Lean-angle capability is rated at 28.5 degrees on both the right and left sides. These measurements were tested using J1168 standards. Equal lean-angle figures support balanced turning characteristics during directional transitions.
Integrated Rider Safety Technologies
The 2026 Harley-Davidson® Street Bob® includes several electronic rider-assistance systems focused on traction management and stability support. Standard equipment includes the Traction Control System, the Drag-torque Slip Control System, and the Tire Pressure Monitoring System.
Cornering Enhanced Traction Control System is also included. This system monitors lean-angle conditions and rear-wheel traction input during acceleration. Cornering Drag-torque Slip Control System assists with rear-wheel management during aggressive downshifts or abrupt throttle reduction.
The Tire Pressure Monitoring System provides active tire-pressure status through the motorcycle instrumentation display. Vehicle Hold Control, Electronic Linked Braking, Wheel Lift Mitigation, and Enhanced Lift Mitigation are not included on this model.
Instrumentation and Electrical Features
The 2026 Harley-Davidson® Street Bob® uses a 4-inch analog speedometer integrated with a digital information display. The instrumentation system provides gear position indication, odometer data, fuel level monitoring, ride-mode information, heated gear indication, traction control status, ABS indication, Tire Pressure Monitoring System data, cruise control status, clock functions, trip information, range calculations, and tachometer information.
The electrical system uses a sealed maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp-hours. Cold cranking output is rated at 310 CCA at 0°F. Charging is managed through a three-phase 48-amp system. Charging output is rated at 364 watts at 13 volts and 900 rpm, with maximum output reaching 624 watts at 13 volts and 2,000 rpm.
The starting system uses a 1.6 kW electric starter with solenoid shift starter motor engagement. Lighting components are fully LED-based. The headlamp includes low beam, high beam, and signature position lamp functionality. Front and rear turn signals use LED bullet-style housings. Tail and stop lamps also use LED bullet-style lighting assemblies.
A USB-C Type power outlet is included with 5V and 2.4-amp output capability. This outlet supports charging compatibility for portable electronic devices.
Fuel Capacity and Efficiency Metrics
