Motorcycle specifications Harley-Davidson 1870 Softail Low Rider S FXLRS 2021 A rumbling story
presentation of the 1870 Softail Low Rider S FXLRS 2021
Riding on a wave of success that continues unabated, the Low Rider is not only a machine particularly appreciated by Harley customers, but also a model that knows how to play versatile. Less so here, where it's decided to be mean instead, with an S version packed with displacement and torque thanks to a bigger engine.
Decided to be mean? Or rather, to be mean again. The Low Rider already had an S edition in 2016 / 2017. A time when its backbone was called Dyna, and housed the biggest twin in the range: the 1800 cm3 110 ci block, reserved for Custom Vehicle Operation machines.
This time, the heart is even bigger. Total cubic capacity reaches 1868 cm3, providing a torque gain of 1 mkg since the standard Low Rider. A moment of robustness, a sprinkling of vigor, an authority that every piston wants to dictate. With power and torque levels virtually identical to those of the previous-generation S. Except that the technology and character are no longer on the same level.

No big block for this gangster machine, but a big block all the same. The Milwaukee Eight is rich in emotion, benefiting from all the modernity of Harley and then expressing itself through a chassis that's sharper than on the Low Rider 107. With a front end as muscular as that of an FXDR 114, you can smell a fight at every turn. Whereas the Low Rider uses a conventional fork with a single brake disc, the rebel S is equipped with a 43 mm inverted fork, complete with two 4-piston shoes on two 300 mm discs. The column angle has been retracted by 2°, to 28°, for more incisive cornering. The Low Rider S wants a dose of fierceness, so it shows it: small black windscreen, higher handlebars, single-seater saddle with a kidney-hugging profile, several shades of black finish for the engine, exhausts and chassis, bronze-colored rims for show-off, and for the rest of the invective, just get started.
Is this Low Rider S a thug? No. Embellished by a big engine and improved dynamics, this custom is akin to an American baron. It doesn't transcend the attributes of theex-FXLRS 110; it just brings them up to date. It doesn't necessarily need anything more; we'd expect nothing less. Roads and parties can simper in front of this bad-boy bike... those from the nicer neighborhoods.
