Motorcycle specifications Harley-Davidson1870 Softail Fat Boy FLFBS 2021 Majority expression

Harley wanted to revamp one of its most iconic machines. For 2021, this modernization means... shiny chrome instead of satin chrome. A rather slight evolutionary move, but entirely in keeping with the company's communications strategy. In any case, we don't touch the Fat Boy, except during the great Softail turnaround that ousted the Dyna. This piece of stylistic marble and steel with a patina of history couldn't resist a daring designer. The Fat Boy is even more Fat, and its forehead is now more neo than retro.

It was a daring move. And Harley dared. The face of this Fat Boy will shake some people up. Still hooded, the headlight has clearly gone modern. With a hint of Suzuki VZR 1800 Intruder. A breath of impertinence that only grazed the forks, leaving the whole silhouette in its comfortable absorbent cotton of conformism. A touch of zest, however, for the rims, with their American muscle-car-like presence. The tires become monstrous: 240 at the rear, and a 160 at the front - the widest ever fitted to a production H-D. Once the mount of the Terminator, the Fat Boy would fit right in with Fast & Furious.

a cheekiness that the bike can fully assume thanks to the Milwaukee Eight engine. At 1870 cm3, the cylinders are more than capable of delivering big torque. 15.8 mkg of torque are used to hammer the rear gumshoe, which is now 240 mm wide (+ 40 mm). That's no less than 3 mkg more than the Twin Cam 103. Purists may cough at the knowledge that 4 valves per cylinder. But this modern block, designed to last and evolve, is sure to put a smile on your face. A more intimidating air filter, emblazoned with the displacement (in cubic inches), reminds the rider of the bike he's looking at.
With such a cubic capacity, it takes over from the thundering Fat Boy S of 2017, set alight by the Twin Cam Screamin'Eagle of ex-CVO.

Fat Boy in spirit and Softail in technique. As a result, the machine benefits from Harley's major evolution. The frame, redesigned, reinforced and lightened, requires 50% fewer parts and 22% fewer welds. Almost 6 kilos lighter, it is 65% stiffer. All in all, the overall chassis rigidity has been improved by 34%.
An improvement in handling, enhanced by new suspension. The rear is completely redesigned with a monoshock (with easy preload adjustment), while the front uses the same forks as the Touring models. To conclude, and going against its name, the new-generation Fat Boy loses weight. Technical upgrades have shaved off 16 kilos.
