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

Milwaukee-Eight® 117 Classic V-Twin

Every ride starts with the heartbeat of the Milwaukee-Eight® 117 Classic. Rated at 98 horsepower with 120 ft-lbs of torque at just 2,500 rpm, it delivers the immediate, low-end thrust riders expect from a big-bore Harley-Davidson® V-Twin. The 4.075-inch bore and 4.5-inch stroke provide a broad, usable powerband, while the 10.3:1 compression ratio and Electronic Sequential Port Fuel Injection (ESPFI) deliver crisp fueling under throttle. Tactile and responsive, the 117 Classic pairs authentic V-Twin character with refined manners — smooth at cruising speed, assertive when you ask for more. Whether threading traffic or overtaking on a country two-lane, the engine’s torque-first tuning makes the bike easy to ride quickly without constant downshifts. It is a powertrain that respects the Street Bob®’s minimalist ethos yet gives you far more headroom than its stripped silhouette suggests.

Two-into-One Exhaust

The Street Bob® channels its energy through a torque-focused 2-into-1 exhaust with a catalyst in the header. Beyond its muscular note, this layout strengthens midrange delivery, smoothing the engine’s transition from initial roll to sustained acceleration. On real roads, that matters — pulling away from lights, driving out of corners, and merging with authority. The system’s tuned length and collector design help the 117 breathe efficiently while maintaining a clean, compact line that complements the bike’s bobber stance. The result is a soundtrack that feels right-sized for daily riding and a response curve that makes the most of each gear. Pair it with the Street Bob®’s sensible overall ratios and you get acceleration that feels effortless, with fewer shifts and a more relaxed rhythm.

Cornering Rider Safety Enhancements

Confidence is part of performance, and the Street Bob® equips it as standard. The Anti-lock Brake System (ABS) and Traction Control System (TCS) form the backbone, supported by Drag-Torque Slip Control System (DSCS) to mitigate rear-wheel slip during abrupt deceleration or downshifts. Tire Pressure Monitoring System (TPMS) keeps tabs on inflation, helping protect tire life and ride quality. Cornering Enhanced Anti-lock Brake System (C-ABS), Cornering Enhanced Traction Control System (C-TCS), and Cornering Drag-Torque Slip Control System (C-DSCS) add sophistication: by accounting for lean angle, brake pressure and traction interventions are tuned for the dynamics of a motorcycle in a turn. The upshot is smooth, predictable behavior if you encounter gravel in an apex, a rainy commute, or a cold morning ride — systems that stay in the background until they are needed, then act to preserve control.

Dual-Bending Valve Front Suspension and Hidden Monoshock

A chassis is more than geometry — it is communication. The dual-bending valve 49 mm front fork delivers improved compliance across a range of inputs, filtering out chatter and supporting clean corner entries. At the rear, a hidden free-piston coil-over monoshock with a 43 mm stroke and cam-style preload adjustment lets you dial in ride height and sag for your weight and cargo. Combined with a 30-degree rake, 6.2 inches of trail, and a 64.2-inch wheelbase, the Street Bob® feels neutral and planted. It tips in without nervousness, tracks lines with minimal correction, and responds well to mid-corner adjustments. Strong braking performance — a 4-piston fixed front caliper and 2-piston floating rear, with solid uniform expansion rotors — matches the chassis’ intent, providing confident, linear deceleration that complements the bike’s nimble nature.

4-Inch Analog Gauge with Selectable Ride Modes and USB-C

The cockpit keeps the Street Bob® honest: an analog speedometer for quick-glance legibility, integrated with digital readouts for ride modes, gear position, odometer, fuel level, range, traction control, ABS, TPMS, and more. Selectable ride modes let you tailor throttle response to conditions and preference, adding a layer of control without clutter. USB-C charging brings practical utility — power navigation, a communication device, or a camera on the go. All-LED lighting, from the headlamp with signature position lamp to the bullet-style LED stop/tail/turn signals, enhances conspicuity and modernizes the silhouette. Cast Annihilator wheels come standard for durability and easy cleaning, and optional painted aluminum tubeless laced wheels are available if you want a classic spoke look with tubeless convenience. Together, these details deliver an interface that is simple, informative, and thoroughly modern.
