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

Milwaukee-Eight® 117 Classic V-Twin

The Milwaukee-Eight® 117 Classic anchors the Street Bob® with the unmistakable feel of a big-bore American V-Twin. With a 4.075-inch bore and 4.5-inch stroke for 117 cu in of displacement and a 10.3:1 compression ratio, it is tuned for accessible, street-ready torque. The numbers tell the story—120 ft-lbs at 2,500 rpm and 98 HP at 4,600 rpm—yet the experience is even better: immediate response, broad midrange, and the steady cadence you expect from a Harley-Davidson®. ESPFI keeps fueling precision, while the primary drive and six-speed ratios are set for punching off the line and easy highway cruising. Whether you are threading through traffic or rolling on from 50 to 70 mph, the 117 Classic makes the bike feel light under you, with power that is always right there.

Two-into-One Exhaust with Street-Ready Performance

Harley-Davidson® fit the 2026 model with a torque-tuned 2-into-1 exhaust that complements the 117’s character. By optimizing scavenging and backpressure, the system sharpens low-to-midrange response—exactly where you ride most of the time. This is not just about sound and style, though both are unmistakably bobber; it is about crisp throttle pickup, strong corner exits, and steady pull through the gears. The catalyst-in-header design supports clean performance, while the routing and finish frame the bike’s minimal silhouette. Paired with the Softail® chassis and Ride Modes, the exhaust helps the Street Bob® feel eager everywhere from short urban hops to longer stretches where you settle into the engine’s sweet spot.

Cornering Rider Safety Enhancements

Rider Safety Enhancements are standard, and the Cornering suite adds confidence when the road turns unpredictable. Cornering Enhanced Anti-lock Brake System (C-ABS) modulates brake pressure with lean angle in mind, helping reduce wheel slip in a turn. Cornering Enhanced Traction Control System (C-TCS) tempers rear-wheel spin when you accelerate upright or in a lean. Cornering Drag-Torque Slip Control System (C-DSCS) helps prevent rear-wheel slip or lock when you rapidly close the throttle or downshift aggressively. The base systems also reinforce your margin: ABS for straight-line braking stability, TCS to keep power in check, and Drag-Torque Slip Control for controlled deceleration. Add Tire Pressure Monitoring System (TPMS) alerts on the display, and you have a connected safety net that works quietly in the background until you need it.

4-inch Analog Gauge with Selectable Ride Modes

The 4-inch analog speedometer integrates a digital information panel that is easy to read at a glance. You see gear position, odometer, fuel level, ride mode selection, traction control, and ABS status, TPMS, clock, trip, estimated range, and tachometer indication in one compact layout. Selectable Ride Modes adjust throttle response and traction management to suit preference and conditions—ideal when you want a calmer setup for slick pavement or a livelier feel on a dry morning. USB-C charging lets you power a navigation or a mobile device, and all-LED lighting ensures you remain visible. This is the right tech in the right dose: intuitive to use, minimally intrusive, and focused on the ride.

Softail® Chassis, Suspension, and Wheels

The Street Bob® rides on a stiff, lightweight Softail® chassis that translates input precisely—quick to turn, steady mid-corner, and planted on exit. Up front, a 49 mm telescopic fork with dual-bending valve technology and gaiter covers delivers controlled damping over chop without harshness. Out back, a hidden, free-piston coil-over monoshock with 43 mm stroke and cam-style preload adjustment keeps the stance low while maintaining travel and support. Black Annihilator cast aluminum wheels pair with Dunlop® Harley-Davidson Series bias blackwall tires—100/90B19 up front and 150/80B16 at the rear—for composed grip and predictable feedback. Optional painted aluminum tubeless laced wheels add a classic look with modern function. Solid, uniform-expansion rotors and a 4-piston front/2-piston rear caliper setup round out a package that feels agile in town and unflappable on rougher backroads.
