Overview

Imagine a straight road cutting through Nevada in the early morning, the asphalt still cold, the sky shifting from indigo to copper. That's why they built the Road King Special. Not to navigate roundabouts, not to impress café terraces: to swallow miles with a quiet authority, the kind that belongs to someone who has nothing to prove but knows exactly where he's going.

Harley-Davidson 1745 ROAD KING SPECIAL FLHRXS

Milwaukee offered the Road King in three versions for 2017, then 2018, and this Special occupies a particular position within the trio. Where the standard version plays functional sobriety and the Classic claims deliberate nostalgia, the Special adopts an entirely different stance. Harley pulled out the black paint and methodically emptied it onto almost every surface: engine guards, mirrors, turn signals, engine covers, mufflers, heat shields, forks. The result is a dark, cohesive visual mass, coiled like a clenched fist. The Mini-Ape handlebars complete the picture by tilting the rider slightly forward, without tipping into the discomfort of radical positions. This is a motorcycle that wants to look menacing while remaining usable over 300 miles at a stretch.

The wheels deserve a closer look. Gone are the 16-inch units of old: the Special runs 19-inch Turbine rims up front and 18-inch at the rear, shod with 130/60 and 180/55 tires respectively. This change noticeably reshapes the front profile — the prow gains character, and the steering gains stability over long distances. The rear tapers with integrated saddlebags that wrap around the exhaust outlets; the seat lowered by 10 millimeters brings the seat height down to 695 mm, manageable for an average-sized rider despite the 372 kg fully loaded. Because the weight must be addressed: it's there, real, unavoidable. The Road King Special is not a motorcycle you toss around. It demands respect, anticipation, a composed riding style. Forget comparisons with an Indian Scout or a Honda CMX 1100 — this segment has nothing to do with lightweight.

Harley-Davidson 1745 ROAD KING SPECIAL FLHRXS

Beneath the near-total black of the engine, the Milwaukee-Eight 107 cubic inch turns over 1746 cc with a bore and stroke of 100 x 111.1 mm, four valves per cylinder and a compression ratio of 10:1. The claimed output is 89 horsepower at 5,450 rpm, but that figure says little about real-world use. What matters is the torque: 149 Nm available from 3,250 rpm — more than 15 mkg over the old unit. The gain in roll-on performance compared to the Twin Cam 103 is noticeable from the first miles. The six-speed gearbox paired with belt final drive does the rest, with a smoothness that former primary-chain owners will appreciate without any particular nostalgia. Some vibration persists at high revs — period character, as expected — but nothing that compromises comfort over a full day's riding.

The suspension received genuine attention with this generation. The 49 mm dual-valve telescopic fork and rear emulsion shocks work better together than what Harley had accustomed us to. Travel remains modest — 117 mm at the front and 76 mm at the rear — but the filtering of road imperfections is noticeably improved. The dual 300 mm front disc brakes with four-piston calipers inspire confidence, though ABS remains a mental prerequisite when managing this much mass. At €25,390, the Road King Special is clearly positioned for a market of connoisseurs. It's not for a freshly minted license holder, nor for someone still undecided between cruiser and adventure bike. It speaks to the seasoned tourer who wants a character machine capable of crossing a continent on the 22.7-liter tank with the serenity of an engine that never runs short of breath. The rest is a matter of finding the right road.
