The 2020 Harley-Davidson FLSL, commonly known as the Low Rider S, is a modern take on a classic American cruiser. Introduced as part of the Softail family, it has been a popular model since its inception in this iteration. The FLSL is characterized by its aggressive, dark styling and a focus on rider engagement. It typically features a single model year with minimal trim variations, emphasizing its specific performance-oriented cruiser appeal. Its popularity stems from its potent engine, blacked-out aesthetic, and a more performance-tuned suspension compared to other Softail models, attracting riders who want both style and substance.
The Good

The 2020 FLSL offers a potent Milwaukee-Eight 114 engine for thrilling performance, a rugged design that exudes iconic Harley-Davidson cool, and surprisingly agile handling. Its comfortable riding position and quality build appeal to both the desire for freedom and the need for a dependable ride.

The Bad

Owners often note the limited suspension travel, which can lead to a firm ride on rough roads. Wind protection is minimal due to its minimalist fairing, and luggage capacity is also restricted, making long-distance touring less comfortable without modifications.

What Problems Does the 2020 Harley-Davidson FLSL Have?

The 2020 Harley-Davidson FLSL, benefiting from the established Milwaukee-Eight engine platform, generally exhibits good reliability. However, like many motorcycles, there are some common owner observations and potential issues to be aware of. One frequently mentioned aspect is related to the suspension, particularly the rear monoshock. While tuned for performance, some riders find it can feel a bit harsh over significant bumps or rough pavement. This is more of a characteristic than a flaw, but it's worth noting for those prioritizing plush comfort. Another area some owners have reported is related to the electronic throttle control. While not widespread, occasional reports of minor throttle response inconsistencies or sensor issues can occur, though these are typically resolved with software updates or minor adjustments.

For the 2020 model year specifically, there haven't been any widely publicized, systemic major mechanical failures unique to the FLSL. Harley-Davidson does issue recalls periodically for various models, and it's always advisable to check the VIN against the NHTSA (National Highway Traffic Safety Administration) database for any outstanding recalls. These can range from minor software updates to more significant component checks. In terms of long-term reliability, the Milwaukee-Eight engine is known for its robust construction. Regular maintenance, as outlined in the owner's manual, is crucial. This includes timely oil changes, filter replacements, and proper care of the primary and transmission fluids. Owners who adhere to a strict maintenance schedule generally report excellent longevity from their FLSL, with many anticipating hundreds of thousands of miles of service. The electrical system, while generally reliable, can sometimes be a source of minor gremlins in any vehicle over time, but there are no overwhelming concerns specific to the 2020 FLSL model year.

How long will the 2020 Harley-Davidson FLSL last?

The 2020 Harley-Davidson FLSL, with its robust Milwaukee-Eight 114 engine and solid construction, is designed for longevity. Based on owner experiences and general Harley-Davidson durability, a well-maintained FLSL can realistically achieve 100,000 miles or more. Many owners aim for significantly higher mileage, with some reporting over 150,000 miles. The primary factor influencing long-term durability is consistent adherence to the recommended maintenance schedule, including regular oil changes, filter replacements, and checking belt tension. While the engine and drivetrain are very durable, potential weaknesses over time might include wear on suspension components and the clutch, especially with aggressive riding. The electrical system, while generally reliable, can also require attention as the bike ages. Overall, the FLSL is built for the long haul, especially for riders who prioritize proper upkeep.

What Technology & Safety Features are Included?

The 2020 Harley-Davidson FLSL focuses on a classic riding experience, with technology integrated to enhance rather than dominate. Standard features include a digital riser-mounted tachometer with a digital speedometer, gear indicator, fuel gauge, clock, trip meters, and engine diagnostics. It boasts an LED Daymaker headlight for superior illumination and an LED taillight for enhanced visibility. For rider safety, Anti-lock Braking System (ABS) is typically standard equipment on this model year, helping to prevent wheel lock-up during braking.

There isn't an integrated infotainment system with features like a touchscreen display, Bluetooth connectivity for music streaming, or navigation in the traditional automotive sense. The focus is on the mechanical feel and sound of the motorcycle. However, owners can opt for various Harley-Davidson accessories to add functionality. These might include upgraded sound systems that can be integrated into the fairing or handlebars, smartphone mounting solutions, and GPS units.

Driver-assistance features as commonly found in cars are absent, as the emphasis is on direct rider control. There are no advanced cruise control systems beyond basic throttle lock mechanisms or lane-keeping assist.

Crash-test ratings for motorcycles are not conducted in the same manner as for cars by organizations like the NHTSA. Instead, safety is assessed through the design of the motorcycle, its braking systems (like the standard ABS), lighting, and structural integrity. The FLSL is designed with a sturdy frame and robust components, contributing to its safety profile.

The used market for a 2020 FLSL currently sees prices ranging from around $17,000 to $23,000, with variations based on mileage, condition, and any aftermarket modifications. Harley-Davidsons, particularly popular models like the Low Rider S, tend to hold their value well compared to many other motorcycle brands. Depreciation is most significant in the first few years, but after that, values stabilize.

Repair costs can be higher than average if specialized Harley-Davidson parts or labor are required.

How Does the 2020 Harley-Davidson FLSL Compare to Other Motorcycle?

The 2020 Harley-Davidson FLSL competes in the power cruiser segment, often facing off against rivals like the Indian Chieftain, Ducati Diavel, and certain models from Yamaha or Kawasaki. In terms of performance, the FLSL's Milwaukee-Eight 114 engine delivers strong torque and acceleration, making it a potent performer for its class. It often edges out some competitors in raw grunt, though bikes like the Diavel might offer superior outright horsepower and sharper handling due to their sportbike underpinnings.

Features on the FLSL are deliberately minimalist, focusing on the riding experience. This contrasts with more tech-laden cruisers from Indian or touring-oriented models that offer infotainment systems, advanced audio, and more creature comforts. The FLSL's strengths lie in its iconic Harley-Davidson styling and focused cruiser aesthetic.

Reliability is a strong suit for the Milwaukee-Eight platform, generally considered robust. While competitors like Indian have improved significantly, Harley-Davidson's long history and widespread dealer network can be a plus for parts and service availability.

Price-wise, the FLSL sits in a competitive range, often positioned as a premium offering. It can be more expensive than some Japanese power cruisers but may offer better value than highly specialized European alternatives.

Similar or Better Alternatives:
  • Indian Chieftain/Dark Horse: Offers more features, comfort, and a comparable engine size, often at a slightly higher price point. It's a strong contender for those wanting more touring capability and tech.
  • Ducati Diavel: For riders prioritizing sportbike-like handling and exhilarating performance with a more exotic flair, the Diavel is a superior choice, albeit at a higher cost and with a more aggressive riding posture.
  • Triumph Bonneville Bobber/Speedmaster: If a more classic, British take on the cruiser aesthetic with excellent build quality is desired, these are worth considering, though their engines are typically smaller and less powerful.
  • Yamaha MT-07/XSR700 (or larger models): For a more agile, lighter, and potentially more affordable power cruiser experience with modern tech, Japanese offerings can be compelling, though they lack the distinct Harley-Davidson heritage.
The FLSL remains a compelling choice for those who value its specific blend of raw power, iconic styling, and the authentic Harley-Davidson experience, provided they don't require extensive technological amenities.

Final Verdict: Is the 2020 Harley-Davidson FLSL a Good Motorcycle?

The 2020 Harley-Davidson FLSL is ideal for riders who appreciate a potent, performance-oriented cruiser with a distinct dark, aggressive aesthetic and the iconic Harley-Davidson heritage. It's best suited for those who prioritize engaging riding dynamics and a stripped-down, focused experience over extensive tech features or touring comfort. It's worth buying, especially on the used market where it offers significant value compared to its original price. Buying used is generally recommended, as the initial depreciation has already occurred. Look for models with good maintenance records and minimal modifications. If you're seeking a motorcycle that makes a statement and delivers a visceral riding experience, the FLSL is an excellent choice. For those needing more comfort or technology, alternatives might be more suitable.
