Key Features of the 2026 Harley-Davidson® Street Bob®

Milwaukee-Eight® 117 Classic V-Twin

The heart of the Street Bob® is Harley-Davidson’s 117 cu in Milwaukee-Eight® 117 Classic. It produces 120 ft-lbs of torque at 2,500 rpm and 98 HP at 4,600 rpm, delivering a deep reservoir of low-to-midrange thrust. A 10.3:1 compression ratio, 4.075-inch bore, and 4.5-inch stroke create a torque curve you can feel in every gear. Thanks to Electronic Sequential Port Fuel Injection (ESPFI), fueling is precise and predictable, helping the engine respond smoothly to small throttle inputs in town and decisive twists when merging or overtaking. The primary drive uses a 34/46 chain ratio to translate the engine’s output into crisp acceleration, while the six-speed gearbox (with well-spaced overall ratios from 9.311 in 1st to 2.79 in 6th) keeps the motor in its sweet spot whether you are rolling through city blocks or cruising at steady-state rpm.

Two-into-1 Exhaust with Street-Ready Performance

The Street Bob® channels its muscle through a 2-into-1 exhaust with a catalyst in the header, tuned for a strong torque signature that complements real-world riding. The single muffler design helps concentrate mass low and central, contributing to the bike’s balanced feel when you tip into a corner or make tight maneuvers. Beyond the classic tone, the exhaust’s flow dynamics support roll-on acceleration where riders spend most of their time—between 2,000 and 4,000 rpm. It is the kind of system you appreciate every time you pull away from a light or transition lanes—responsive, straightforward, and built to work seamlessly with the Milwaukee-Eight® 117 Classic.

Selectable Ride Modes + 4-inch Display

At first glance, you see a clean, 4-inch analog speedometer. Look closer, and you will appreciate the digital integration: gear indicator, odometer, fuel level, ride modes, heated gear status, traction control, ABS, TPMS, cruise control, clock, trip functions, range, and a tachometer readout. Selectable Ride Modes tailor throttle response and intervention thresholds for different conditions, giving you a consistent feel and control as streets change block by block. The interface strikes that ideal balance—classic analog readability with digital depth when you want it. Add USB-C charging for your device, and you have a compact cockpit that is functional without clutter, exactly in keeping with the Street Bob® philosophy.

Rider Safety Enhancements with Cornering

Standard Rider Safety Enhancements provide an additional layer of confidence. Systems include Anti-lock Brake System (ABS), Traction Control System (TCS), Drag-Torque Slip Control System (DSCS), and Tire Pressure Monitoring System (TPMS). Cornering Enhanced Anti-lock Brake System (C-ABS), Cornering Enhanced Traction Control System (C-TCS), and Cornering Drag-Torque Slip Control System (C-DSCS) further refine stability by accounting for lean angle during braking, acceleration, or deceleration on varying surfaces. These technologies do not intrude on the bike’s raw character; rather, they act in the background to help the motorcycle maintain traction and composure in unexpected moments. Think slick manhole covers, painted lines, or a sudden need to slow mid-corner—the suite is designed to support smooth, predictable control.

Softail® Chassis, Suspension, and Ergonomics

The raw, rigid-look Softail® frame underpins the Street Bob® with modern compliance. Up front, a dual-bending valve 49 mm telescopic fork manages bumps with progressive damping. In back, a hidden, free-piston coil-over monoshock (43 mm stroke) pairs with cam-style preload adjustment to balance comfort and control. Geometry is set for agile, stable behavior: 30 degrees of rake, 6.2 inches of trail, and a 64.2-inch wheelbase. Lean angles of 28.5 degrees (left and right) support confident cornering. Black Annihilator cast aluminum wheels are standard, with painted aluminum tubeless laced wheels available for riders who want the laced look without inner tubes. Braking is handled by a 4-piston fixed front caliper and 2-piston floating rear, working with solid, uniform expansion rotors. The 25.8-inch laden seat height and narrow midsection help a wide range of riders get comfortable and command the bike from the first ride.
