Overview

What drives a rider to drop nearly 20,000 euros on a machine stripped of every superfluous comfort? The answer comes down to two words: Street Bob. This 2023 Harley-Davidson doesn't try to win you over with technology or features. It grabs you by the collar with its 1868 cc V-twin and its hatchet-hewn bobber stance. The deal is simple. You get on, you twist the throttle, and Milwaukee hits you right in the gut.

Harley-Davidson 1870 Softail Street Bob FXBB

The big change on this generation is the switch to the Milwaukee-Eight 114 powertrain. With its 102 mm bore and 114 mm stroke, this 45-degree V-twin puts out 94 horsepower at 5020 rpm. A modest figure on paper, especially against an Indian Scout Bobber playing in the same price range with a livelier temperament. But the Street Bob isn't defined by its power alone. Its knockout argument is the torque: 154.9 Nm available from just 3250 rpm. At that engine speed, the motor pulls like a locomotive diesel, and every roll-on with a whiff of throttle becomes a small blissful ritual. The 10.5:1 compression ratio, four valves per cylinder, a six-speed gearbox, and belt final drive round out a mechanical package calibrated for straight-line pleasure, not the track.

On the chassis side, the Softail platform has definitively buried the old Dyna frame. The tubular steel frame houses a 49 mm telescopic hydraulic fork with 130 mm of travel up front and a hidden mono-shock under the seat, limited to 86 mm of travel at the rear. It's firm, sometimes harsh over road seams, but the handling gains in precision over the old architecture. The seat perched at just 680 mm makes for easy confidence at a standstill — a real asset for shorter riders. On the other hand, the 297 kg wet weight is a quick reminder that this bike demands some muscle during low-speed maneuvers. Braking, handled by a 300 mm disc clamped by a four-piston caliper up front and a 292 mm disc at the rear, gets the job done without any particular brilliance. On a machine topping out at 160 km/h, nobody's asking for more.

Harley-Davidson 1870 Softail Street Bob FXBB

Let's talk style. Wire-spoke wheels, fork gaiters, raised Shotgun exhaust pipes, dark paint, and a gauge pared down to the bare minimum: the Street Bob cultivates a raw aesthetic that will appeal to American custom purists. Anything that might soften the line has been removed. The 13.2-liter tank limits range and forces frequent fuel stops, which clearly confines the machine to urban cruises and Sunday rides on back roads. Harley did add a passenger seat, but with the comfort of a postage stamp and the complete absence of grab handles, you have to wonder whether it's an invitation or a deterrent.

Harley-Davidson 1870 Softail Street Bob FXBB

At 19,890 euros, the Street Bob FXBB is aimed at the rider who wants the uncompromising bobber look, who's willing to sacrifice comfort for the sake of attitude and mechanical thunder. Up against a more versatile Triumph Bonneville Bobber or a higher-performing Indian Scout Bobber, it plays the card of American authenticity and radical minimalism. This is a motorcycle of conviction, not of reason. If you're looking for a practical, comfortable tool, move along. If you want to feel every firing pulse in the V-twin travel up your spine, Bob is waiting.
