Overview

Picture an ocean-liner ferry converted into two wheels, chromed down to the rivets, ready to swallow a tarmac transatlantic between Bordeaux and Saint Petersburg. That's roughly the silhouette drawn by the 1870 Ultra Limited FLHTK, 2021 vintage, this Milwaukee steamship set on 416 kg fully fueled, or 399 dry if you want to reassure yourself with numbers that mean nothing once it's on the side stand. At 31,190 euros, you're not buying a motorcycle, you're signing a lease with the asphalt.

Beneath the flanks of the Batwing fairing sits the Milwaukee Eight 114, a 45-degree V-twin that spits out 1868 cc through four valves per cylinder and a compression ratio of 10.5 to 1. The 90 horsepower claimed at 5020 rpm seem almost modest on paper, until you look at the block's true signature, those 163.8 Nm delivered as early as 3000 rpm. It's this mover's torque, not the cavalry, that pushes the ship forward, and that explains why the six-speed belt-drive gearbox is content to stay in fourth from the Vemars tollgate all the way to Frankfurt. The balance shaft filters out most of the shuddering at idle, the mixed air-liquid cooling draws heat from the cylinder heads, and the Big Twin has finally reached its industrial maturity without betraying its character.

Any comparison with the competition falls short, so locked down is the genre. The Honda Gold Wing DCT plays in an entirely different register, more surgical, more Asian in its smoothness. The Indian Roadmaster remains the only true stylistic rival, with its Thunderstroke 116, often judged more modern in its chassis. Against them, the Harley banks on mythological capital, that timeless fairing head, that twin tubular steel cradle that never pretended to draw curves, and a 740 mm seat height that lets you plant both feet flat even in raw unwashed denim. The 49 mm telescopic fork offers 117 mm of travel, the two side shocks make do with 76 mm, adjustable for preload via a dial, and that's more than enough as long as you don't ask the beast to slalom through the hairpins of the Galibier.

The braking deserves a word. Two 300 mm front discs pinched by four-piston calipers, a single rear disc in the same configuration, all managed by Reflex Link which electronically links the two ends according to lean angle and speed. Add the switchable traction control with Rain mode, the anti-slip that contains torque surges under downshifting, hill-start assist, TPMS and cornering ABS. The kind of kit we saw yesterday on German hypersports, now equipping this 170 km/h top-speed behemoth. The 22.7-liter tank permits 300 km stages without range anxiety.

That leaves the question of the audience. This is neither a beginner's motorcycle nor an urban toy. Handling 416 kg at a standstill takes craft, and parking-lot maneuvers on a slope are negotiated with the thighs. It's the mount of the long-haul tourer, of the couple setting off for three weeks in Norway with the Tour-Pak luggage locked shut with one press of the One-Touch button, of the rider who favors the 6.5-inch TFT screen with CarPlay compatibility and the 25 watts per channel of the Boom Box GTS over circuit lap times. You pay dearly, you weigh heavy, you ride far. For those it makes dream, no other equation holds up.
