2020 Harley-Davidson Low Rider S FXLRS: First-Year Milwaukee-Eight 114 Softail Performance Cruiser
The 2020 Harley-Davidson Low Rider S, factory code FXLRS, was the first Low Rider S built on the Milwaukee-Eight Softail platform. It replaced the short-lived but highly regarded 2016-2017 FXDLS Dyna Low Rider S in spirit rather than in chassis architecture, carrying the blacked-out performance-cruiser attitude into Harley-Davidson’s consolidated Softail generation.
Its importance lies in the way Harley-Davidson translated the Dyna-era “club-style” performance formula into the new Softail frame: Milwaukee-Eight 114 power, inverted fork, dual front discs, a high bar position, black finishes, bronze wheels, and a tauter stance than the standard Low Rider. For collectors and serious Harley buyers, the 2020 model is significant as the first-year Softail Low Rider S and the only opening chapter before later Low Rider S and Low Rider ST variants pushed the platform further.
Best Known For: The 2020 FXLRS is best known as the first Softail Low Rider S, combining the counterbalanced Milwaukee-Eight 114 engine with Harley-Davidson’s hidden-monoshock Softail chassis and a factory performance-cruiser specification.

The FXLRS was not a limited-production homologation model, a police motorcycle, or a racing derivative. Its appeal is more modern and more specific: it is a factory-built answer to a style of modified Harley that had already been refined by Dyna and FXR riders before the factory brought much of that vocabulary into the showroom.
Why the 2020 Low Rider S Matters
The 2020 Low Rider S deserves its own page because it marks a clean break in the Low Rider S story. The earlier FXDLS was a late Dyna built around the Twin Cam 110 and exposed twin-shock frame; the 2020 FXLRS moved the idea to the stiffer, lighter-feeling Softail architecture with a counterbalanced Milwaukee-Eight 114.
That transition matters to collectors because the Softail Low Rider S was not merely a styling continuation. It changed the motorcycle’s mechanical language: no visible rear shocks, a different engine character, a different chassis stiffness, improved braking hardware, and a more contemporary interpretation of the West Coast performance-cruiser look. The 2020 model is the baseline against which later 117-powered Low Rider S and Low Rider ST machines are often judged.
Historical Context and Development Background
By the time the 2020 Low Rider S appeared, Harley-Davidson had already ended the Dyna line and folded much of its big-twin cruiser range into the Milwaukee-Eight Softail platform. That move was controversial among riders attached to the Dyna’s twin-shock silhouette, but it gave Harley a more modern chassis structure with concealed rear suspension, improved rigidity, and the ability to house the counterbalanced Milwaukee-Eight engine.
The market context was equally important. A strong performance-cruiser subculture had formed around FXR and Dyna models, especially machines with high bars, mid controls, upgraded suspension, fairings, performance exhausts, and dual-disc front ends. The Low Rider S was Harley-Davidson’s factory recognition of that taste, even if many owners immediately personalized the motorcycles further.
The 2020 FXLRS also sat in a particular competitive space. It was not a full-dress touring bike, not a traditional chrome Softail cruiser, and not a sport naked in the European or Japanese sense. It was Harley’s big-inch, torque-led answer to riders who wanted the stance and presence of a big twin but expected more chassis and braking specification than a conventional cruiser offered.
Engine and Drivetrain
The 2020 Low Rider S used the Milwaukee-Eight 114, an air/oil-cooled 45-degree V-twin displacing 1,868 cc. In Softail form the Milwaukee-Eight is counterbalanced, which gives the engine a different physical feel from rubber-mounted Dyna and Touring applications. It retains the Harley big-twin cadence, but with less low-frequency shake transmitted into the chassis at idle and low road speed.
The Milwaukee-Eight’s four-valve cylinder heads, single camshaft, hydraulic lifters, and electronic sequential-port fuel injection make it a thoroughly modern Harley-Davidson big twin, even though its visual architecture still reads as traditional American V-twin machinery. Factory literature emphasized torque rather than horsepower; Harley-Davidson commonly listed the 2020 Low Rider S at 119 lb-ft of torque at 3,000 rpm in U.S. specification.
Primary drive is by chain, with power passing through a multi-plate wet clutch to the six-speed Cruise Drive transmission. Final drive is by belt, consistent with Harley-Davidson’s modern big-twin road motorcycles. The result is a drivetrain designed less around peak revs than immediate midrange thrust, relaxed gearing, and low-maintenance road use.
Engine and Drivetrain Specifications
These are factory-listed or widely documented mechanical specifications for the 2020 FXLRS. Harley-Davidson did not make horsepower the principal published figure for this model in U.S. literature, so it is not treated as a verified specification here.

|---|---|
| Engine | Milwaukee-Eight 114 |
| Configuration | 45-degree V-twin, four valves per cylinder |
| Cooling | Air/oil-cooled |

| Final drive | Belt |
As with many Milwaukee-Eight Softails, the engine responds strongly to exhaust, intake, and calibration changes, which is why completely stock examples can be harder to find than mileage alone might suggest. For collectors, an unmodified intake, original exhaust system, and correct emissions equipment can matter as much as cosmetic condition.
Chassis, Suspension, and Braking
The Softail frame was central to the 2020 Low Rider S. Unlike the Dyna FXDLS, the FXLRS does not use exposed twin rear shocks. Its rear suspension is hidden beneath the seat area, allowing Harley-Davidson to preserve a hardtail-inspired side profile while using a monoshock chassis with a more contemporary structural approach.
The Low Rider S specification added an inverted fork and dual front discs, two of the most visible signs that this was not a standard boulevard cruiser. The wheels were bronze-finished cast aluminum units, a deliberate contrast against the otherwise blacked-out mechanical finish. Visually, the bike was defined by the small headlight screen, high bars on risers, tank console, black powertrain, and compact tail treatment.
Chassis and Equipment Specifications
The table below focuses on reference details useful to buyers and restorers. It avoids comfort or handling claims and sticks to identifiable factory equipment.
| Component | 2020 FXLRS Factory Specification |
|---|---|
| Frame | Steel Softail frame |
| Rear suspension | Concealed coil-over monoshock |
| Front suspension | Inverted fork |
| Front wheel | 19-inch bronze Radiate cast aluminum |
| Rear wheel | 16-inch bronze Radiate cast aluminum |
| Front tire size | 110/90B19 |
| Rear tire size | 180/70B16 |
| Front brakes | Dual disc |
| Rear brake | Single disc |
| ABS | Standard on U.S.-market 2020 Low Rider S |
| Factory colors commonly associated with 2020 | Vivid Black and Barracuda Silver |
The chassis package made the Low Rider S distinct within the Softail line. It was still a long, low Harley-Davidson big twin, but its front-end specification and braking equipment gave it a sharper factory identity than chrome-heavy Softails built around visual nostalgia.
Riding Experience and Mechanical Character
The 2020 Low Rider S starts like a modern Harley-Davidson, without the ritual of a carburetor, choke, or manual advance. The security fob, electronic fuel injection, electric start, and conventional foot-shift controls make it a contemporary motorcycle in use, even though the tank console and big exposed V-twin maintain a traditional visual relationship with the rider.
The Milwaukee-Eight 114 is the center of the experience. It does not need to be revved hard to feel authoritative; the engine’s useful work is done in the lower and middle ranges, with a broad torque delivery that suits short shifting and roll-on acceleration. Compared with the earlier Twin Cam 110 Dyna Low Rider S, the Softail’s counterbalanced engine feels smoother through the frame while still delivering the uneven pulse that defines a Harley big twin.
The clutch and six-speed gearbox are substantial rather than delicate. Engagement has the expected big-twin weight, and the transmission rewards deliberate shifts. The belt final drive removes chain maintenance from the ownership routine and contributes to the clean, low-drama road manners expected of a modern Harley cruiser.
On the road, the Softail chassis gives the FXLRS a more integrated feel than the old Dyna platform, particularly in the way the engine, frame, and suspension behave as one structure. The inverted fork and dual front discs do not turn it into a sport bike, but they do matter: front-end confidence and braking authority are central to the Low Rider S identity. At low speed the motorcycle still feels like a heavy big twin, with wide bars helping leverage; at open-road pace it is more composed than its stripped appearance suggests.
Identification and Originality
Correct identification begins with the factory model code: FXLRS. The 2020 model should be understood as a Softail Low Rider S, not a Dyna Low Rider S, even though sellers sometimes blur the distinction in casual advertising. The visible clues are clear: hidden rear shock layout, Milwaukee-Eight 114 engine, Softail frame architecture, inverted fork, dual front discs, bronze cast wheels, blacked-out finishes, small headlight screen, and high bars on risers.
Originality concerns are different from those on an antique Harley, but they are very real. The most commonly altered parts are exhaust systems, air cleaners, ECM calibrations, handlebars and risers, seats, rear shocks, lighting, mirrors, turn signals, license-plate mounts, and fairing accessories. Many changes improve usability, but they can make a supposedly stock first-year FXLRS difficult to verify.
Collectors should look for the original exhaust, catalyst-equipped components where applicable, factory intake, emissions labels, owner’s manual, key fobs, service records, and any removed take-off parts. Paint and finish condition matter because the 2020 Low Rider S used a strong black-and-bronze visual theme; mismatched wheel finishes, non-original black powder coating, or replaced tins should be questioned carefully.
Frame and engine number integrity should be checked through normal legal-title channels rather than folklore decoding. Harley-Davidson VIN and model information can confirm the model family and year, but buyers should avoid unsupported internet decoding claims and instead rely on the title, factory labels, dealer documentation, service history, and physical configuration.
Model Code and Variant Breakdown
The 2020 FXLRS is best understood by placing it beside the models that enthusiasts most often compare with it. The table below is not a complete Low Rider genealogy, but it covers the relevant model-code relationships for identification, shopping, and collector discussion.
| Model / Code | Years | Engine / Displacement | Purpose | Key Difference |
|---|---|---|---|---|
| Low Rider S / FXLRS | 2020 model year | Milwaukee-Eight 114 / 1,868 cc | Factory performance cruiser | First Softail Low Rider S; inverted fork, dual front discs, bronze wheels, black finish package |
| Low Rider / FXLR | Softail generation from 2018 | Milwaukee-Eight big twin; displacement varied by year and market | Standard Low Rider cruiser | Less aggressive specification; not the S performance trim |
| Low Rider S / FXDLS | 2016-2017 | Twin Cam 110 / 1,801 cc | Late Dyna performance cruiser | Predecessor in concept; Dyna twin-shock chassis and Twin Cam engine |
| Low Rider S / FXLRS | Later Softail continuation | Milwaukee-Eight; later versions received factory changes including 117 cu in specification | Evolved Softail performance cruiser | Not the first-year 2020 configuration; later specification changes affect collector comparison |
| Low Rider ST / FXLRST | Introduced after the 2020 FXLRS | Milwaukee-Eight 117 in factory ST form | Sport-touring-influenced performance cruiser | Adds frame-mounted fairing and saddlebags; related but not a 2020 first-year Low Rider S |
The important collector distinction is simple: a 2020 FXLRS is not merely a “Low Rider with black parts.” It is the first Softail S model carrying the Low Rider performance identity, and its model-code accuracy matters when comparing it with the Dyna FXDLS or later 117-powered machines.
Performance and Dimensional Specifications
Factory figures for the 2020 Low Rider S were built around torque, weight, and chassis dimensions rather than magazine-style acceleration numbers. Harley-Davidson did not consistently publish horsepower for U.S.-market big twins of this period, and reliable 0-60 mph or quarter-mile figures depend heavily on test conditions and source.
| Factory Specification | 2020 Low Rider S FXLRS |
|---|---|
| Engine torque | 119 lb-ft at 3,000 rpm, U.S. factory listing |
| Length | 92.7 in |
| Wheelbase | 63.6 in |
| Rake | 28 degrees |
| Trail | 5.1 in |
| Ground clearance | 4.7 in |
| Seat height, laden | 26.5 in |
| Fuel capacity | 5.0 U.S. gal |
| Weight, as shipped | 650 lb |
| Weight, running order | 679 lb |
Those numbers explain much of the motorcycle’s character. The Low Rider S is long, low, and heavy by general motorcycle standards, but its torque output, front-end equipment, and chassis stiffness distinguish it from softer cruiser interpretations within the same broad category.
Compared With Related Models
2020 FXLRS Low Rider S vs. 2016-2017 FXDLS Dyna Low Rider S
This is the comparison that matters most to enthusiasts. The FXDLS has the emotional pull of the last high-spec Dyna era, with a Twin Cam 110 and visible twin shocks. The 2020 FXLRS is smoother, structurally different, and built around the Milwaukee-Eight Softail chassis. Riders who value Dyna lineage often prefer the FXDLS; riders who want the Low Rider S idea with a more modern frame and drivetrain tend to favor the FXLRS.
2020 FXLRS Low Rider S vs. Softail Low Rider FXLR
The standard Softail Low Rider is visually and mechanically related, but the S model carries the performance brief more clearly. The inverted fork, dual front discs, blacked-out treatment, Milwaukee-Eight 114 specification, and bronze wheels make the FXLRS a more focused motorcycle. Confusion between FXLR and FXLRS listings is common enough that model-code verification is worth doing before purchase.
2020 FXLRS Low Rider S vs. Later 117-Powered Low Rider S
Later Low Rider S models developed the formula further, most notably with factory 117 cu in power in later specification. That does not erase the significance of the 2020 motorcycle. The 2020 FXLRS remains the first-year Softail Low Rider S, and collectors often separate first-year identity from later mechanical upgrades when judging originality and historical position.
Restoration and Ownership Notes
As a modern Harley-Davidson, the 2020 Low Rider S is not difficult to maintain compared with scarce antique or pre-AMF machines. Genuine parts support, aftermarket coverage, tuning knowledge, and specialist familiarity are strong. The challenge is not usually finding parts; it is determining what has been changed and whether those changes were done cleanly.
Common ownership issues revolve around modifications. Exhaust and intake changes may be accompanied by tuning devices or undocumented calibrations. Taller risers can create brake-line, clutch-cable, electrical-routing, and ABS-line concerns. Suspension changes may improve the bike but should be checked for correct fitment, ride height, belt alignment, and evidence of frame or fastener damage.
Engine inspection should include normal Milwaukee-Eight checks: oil leaks, service history, unusual valvetrain noise, evidence of overheating, intake leaks after air-cleaner changes, and the quality of any cam or performance work if present. A stock or lightly modified motorcycle with documentation is generally easier to evaluate than a heavily customized example presented without receipts.
Buyer and Restoration Inspection Points
A 2020 FXLRS can be an excellent used motorcycle, but the performance-cruiser audience modifies these bikes heavily. The inspection should therefore focus less on age-related deterioration and more on correctness, workmanship, and documentation.
| Area | What to Check | Why It Matters |
|---|---|---|
| Model identity | Confirm FXLRS model code through title, factory labels, dealer paperwork, and physical specification | Standard FXLR models are sometimes advertised loosely as Low Rider S-style builds |
| Exhaust system | Look for original exhaust, catalytic components where applicable, sensor wiring, and signs of poor installation | Exhaust swaps are common and affect legality, tuning, value, and drivability |
| Intake and calibration | Check air cleaner type, tuner history, ECM calibration records, and dealer service notes | A poorly matched intake/exhaust/tune combination can create heat, detonation risk, or rough running |
| Handlebars and risers | Inspect cable routing, brake lines, clutch cable, switch wiring, and steering lock-to-lock movement | High-riser conversions are popular and can stress wiring or compromise brake-line safety if done cheaply |
| Front end and brakes | Check fork tubes, seals, calipers, rotors, ABS function, and evidence of impact or curb damage | The inverted fork and dual-disc front brake package are central to the S specification |
| Wheels and finishes | Verify bronze Radiate cast wheels, finish condition, tire sizes, and any repaint or powder-coat work | The black-and-bronze appearance is part of the first-year FXLRS identity |
| Rear suspension and belt | Inspect shock condition, ride-height changes, belt alignment, sprockets, and swingarm area | Lowering or shock changes can affect handling, belt life, and ground clearance |
| Documentation | Ask for service records, original take-off parts, owner’s manual, key fobs, and receipts for modifications | Documentation separates a carefully kept FXLRS from a cosmetically polished but unknown build |
The best examples are not necessarily untouched, but they are coherent. A well-documented exhaust, suspension, or ergonomic change is less worrying than a stock-looking motorcycle with missing records, mismatched finishes, and unexplained wiring.
Collector and Market Relevance
The 2020 Low Rider S occupies a useful place in Harley-Davidson collecting because it is modern enough to be ridden hard and first-year enough to interest buyers who track model transitions. Exact production numbers are not consistently documented in public factory sources, so rarity claims should be treated with caution. Its desirability rests more on configuration, condition, originality, and first-year status than on any verified limited-production narrative.
Collectors typically value unmodified or thoughtfully modified examples with original parts retained. Vivid Black carries the obvious sinister Low Rider S look, while Barracuda Silver gives the first-year bike a more visibly period-specific 2020 appearance. The bronze wheels, blacked-out engine, dual-disc front end, and correct FXLRS equipment should all be present if a seller is asking collector-level attention.
The motorcycle also benefits from its connection to the Dyna performance scene. It is not a Dyna, and serious buyers know the difference, but it was clearly aimed at riders who had made the FXR and Dyna platforms into a performance-cruiser language of their own. That cultural link gives the first-year Softail Low Rider S more significance than a routine trim variation.
Cultural Relevance
The 2020 FXLRS has no military or police legacy and no factory racing record that defines its identity. Its cultural relevance comes instead from club-style Harley practice: tall risers, compact fairings, black components, midrange power, upgraded suspension, and a riding style that values braking and cornering composure more than traditional cruiser posturing.
Harley-Davidson did not invent that scene with the Low Rider S, but the company recognized it. The FXLRS is one of the clearest examples of the factory absorbing rider-built ideas and selling them back in a cohesive production package. That is precisely why the bike matters to younger Harley collectors as well as to older marque loyalists who follow the evolution from FXR to Dyna to Softail.
FAQs
What years were the Harley-Davidson Low Rider S Softail first produced?
The Softail-based Low Rider S began with the 2020 model year under the FXLRS code. Earlier Low Rider S models from 2016-2017 were Dyna FXDLS machines, not Softails.
What engine is in the 2020 Harley-Davidson Low Rider S?
The 2020 FXLRS uses the Milwaukee-Eight 114, an air/oil-cooled 45-degree V-twin with four valves per cylinder and 1,868 cc displacement. U.S. factory literature listed torque at 119 lb-ft at 3,000 rpm.
Is the 2020 Low Rider S a Dyna?
No. The 2020 Low Rider S is a Softail, using Harley-Davidson’s Milwaukee-Eight Softail frame with a concealed rear monoshock. The Dyna Low Rider S was the 2016-2017 FXDLS with a Twin Cam 110 and exposed twin rear shocks.
How do I identify a real 2020 FXLRS Low Rider S?
Look for the FXLRS model identity supported by title and factory documentation, plus the correct Softail chassis, Milwaukee-Eight 114 engine, inverted fork, dual front discs, bronze cast wheels, blacked-out finish package, high bars, and small headlight screen. Avoid relying only on seller descriptions or cosmetic conversions.
Did Harley-Davidson publish horsepower for the 2020 Low Rider S?
Harley-Davidson’s U.S. factory specification for this model emphasized torque rather than horsepower. Because factory horsepower was not consistently published, serious references usually cite the documented torque rating instead of inventing a horsepower figure.
What are the common modifications on a 2020 Low Rider S?
Common modifications include exhaust systems, air cleaners, tuners, handlebars and risers, seats, rear shocks, lighting, fairings, and license-plate mounts. These changes are not automatically negative, but documentation and workmanship are essential when evaluating value and reliability.
Why is the 2020 Low Rider S collectible?
Its collector appeal comes from being the first-year Softail Low Rider S and the factory bridge between the Dyna FXDLS performance-cruiser idea and the Milwaukee-Eight Softail generation. Originality, correct FXLRS specification, retained factory parts, and clean documentation are the key value factors.
Collector Takeaway
The 2020 Harley-Davidson Low Rider S is significant because it marks the moment the Low Rider S identity changed chassis families. The Dyna FXDLS supplied the attitude; the FXLRS supplied the Softail structure, counterbalanced Milwaukee-Eight 114 power, and a more modern front-end and brake package. That makes the first-year Softail Low Rider S a genuine transition model rather than a simple trim exercise.
For a collector, the bike to buy is the one that still reads as a 2020 FXLRS before it reads as somebody’s parts catalog. Original exhaust and intake pieces, correct bronze wheels, proper black finishes, clean documentation, and restrained modifications all matter. The FXLRS will be remembered not because it was rare in the old limited-production sense, but because it captured a major shift in Harley-Davidson’s big-twin performance language at the exact point where Dyna mythology met the Milwaukee-Eight Softail era.
