The 2021 Harley-Davidson FLFBS, commonly known as the Fat Bob, is a modern cruiser with a muscular stance and aggressive styling. Introduced in its current form in 2018, it belongs to the Softail family. The FLFBS is a standout model, distinguished by its distinctive inverted front forks, dual front disc brakes, and a commanding presence. It appeals to riders seeking a blend of classic Harley-Davidson soul with contemporary performance and technology. Pricing for the 2021 model typically ranged from around $20,000 to $22,000 new.
The Good
The 2021 FLFBS offers a powerful Milwaukee-Eight engine for exhilarating performance, a robust build for reliability, and a comfortable ride thanks to its updated Softail frame. Its aggressive, modern design turns heads, while its solid value proposition makes it an attractive long-term investment for riders seeking both style and substance.
The Bad
Potential buyers should be aware of the FLFBS's weight, which can make low-speed maneuvers challenging for less experienced riders. Some may find the stock suspension a bit firm, and the lean angle is not as generous as some other cruisers, potentially limiting aggressive cornering. Fuel range can also be a consideration for long tours.

What Problems Does the 2021 Harley-Davidson FLFBS Have?
For the 2021 Harley-Davidson FLFBS, reports of significant widespread mechanical failures are relatively uncommon, which is typical for well-maintained Harley-Davidson motorcycles. However, as with any production vehicle, some owners have reported minor issues. One area that sometimes garners attention is the electrical system; while generally robust, occasional glitches with sensors or accessory connections can occur. Some riders have noted that the stock exhaust can be prone to discoloration or carbon buildup over time if not properly maintained, which is more of an aesthetic or maintenance concern than a functional failure. Clutch feel and engagement can also be a point of discussion, with some riders finding it a bit heavy, though this is subjective and often improves with break-in or aftermarket adjustments. In terms of recalls, specific to the 2021 model year for the FLFBS, it is crucial to check the National Highway Traffic Safety Administration (NHTSA) database or Harley-Davidson's official recall information. Recalls can be issued for various reasons, including potential issues with braking systems, fuel systems, or electronic components that may arise during production. For the 2021 models, there were no major widespread recurring issues that significantly impacted the long-term reliability of the FLFBS. The Milwaukee-Eight engine platform is generally considered strong and reliable. As always, consistent and proper maintenance is the most critical factor in ensuring the longevity and reliability of any Harley-Davidson. Following the recommended service intervals, using quality fluids, and addressing minor issues promptly will contribute to a trouble-free ownership experience. Owners should be vigilant for any unusual noises, performance changes, or warning lights, and consult a qualified technician if concerns arise. The 2021 model year benefits from the refinements made to the Softail platform in previous years, making it a generally dependable motorcycle.
How long will the 2021 Harley-Davidson FLFBS last?
The 2021 Harley-Davidson FLFBS, with its robust Milwaukee-Eight engine and solid Softail frame, is built for longevity. With diligent adherence to the manufacturer's maintenance schedule, including regular oil changes, filter replacements, and other specified services, owners can realistically expect to see service lives well beyond 100,000 miles. Many Harley-Davidson riders achieve significantly higher mileage, often reaching 150,000 miles or more before major engine work might be considered. The primary factors influencing long-term durability are consistent maintenance, proper riding habits (avoiding excessive abuse), and timely attention to any minor issues that may arise. Weaknesses over time are generally related to wear and tear on components like tires, brakes, and suspension, which are consumables. However, the core mechanicals of the engine and transmission are known for their durability when cared for.
What Technology & Safety Features are Included?
The 2021 Harley-Davidson FLFBS incorporates a respectable suite of technology and safety features, aligning with its modern cruiser persona. Standard tech includes a digital riser-mounted speedometer that displays a variety of information, including gear indication, fuel level, clock, and trip meters. It also features a USB charging port for convenient device connectivity, a welcome addition for riders who rely on their smartphones for navigation or communication. The ignition system is keyless, utilizing a proximity fob for starting and security, enhancing convenience. For safety, Anti-lock Braking System (ABS) is standard on both front and rear brakes, a crucial feature for confident stopping power in various conditions. The lighting system is all LED, featuring a distinctive Daymaker LED headlamp, providing excellent illumination and visibility at night, and enhanced conspicuity during the day. While the FLFBS doesn't offer advanced driver-assistance systems like adaptive cruise control or blind-spot monitoring, its focus remains on the core riding experience. There are no direct crash-test ratings for motorcycles in the same way cars are tested by organizations like NHTSA or IIHS. Motorcycle safety is primarily evaluated through the effectiveness of their engineered safety features and components. Optional features for the 2021 FLFBS typically revolve around customization and performance enhancements, such as different exhaust systems, upgraded audio options (though not integrated infotainment screens), rider comfort accessories, and luggage solutions. The emphasis is on enhancing the rider's connection to the road and the machine, rather than inundating them with complex electronic aids. The technology present on the FLFBS is designed to be functional, intuitive, and enhance the overall riding experience without detracting from the raw character of the motorcycle.

2021 Harley-Davidson FLFBS Prices and Market Value
When new, the 2021 Harley-Davidson FLFBS typically carried an MSRP in the range of $20,000 to $22,000, depending on color options and any factory-installed accessories. Current used market prices for a 2021 FLFBS in good condition with average mileage can range broadly, often between $15,000 and $19,000. Harley-Davidson motorcycles, especially popular models like the Fat Bob, tend to hold their value relatively well compared to many other brands. Depreciation is most significant in the first couple of years of ownership. Factors that greatly affect resale value include the motorcycle's overall condition, mileage, maintenance history (documented service records are a big plus), originality of parts, and the presence of desirable aftermarket modifications. Limited edition colors or special editions can also command higher prices. Market demand also plays a role; the Fat Bob remains a sought-after model due to its aggressive styling and performance.
2021 Harley-Davidson FLFBS Cost of Ownership
Owning a 2021 Harley-Davidson FLFBS involves moderate to high ownership costs. Insurance premiums can vary significantly based on rider age, location, riding history, and coverage levels, but expect it to be pricier than for a smaller motorcycle. Fuel costs are reasonable given the engine size, with an average of 45-50 mpg, but premium fuel is usually recommended. Routine maintenance, including oil changes and filter replacements, can be done DIY or at a dealership, with dealership costs being higher. Repairs, especially for specialized components or engine work, can be costly. Overall, the FLFBS is not an economical choice for budget-conscious riders; it represents a lifestyle purchase where the cost is associated with the brand, performance, and experience.

How Does the 2021 Harley-Davidson FLFBS Compare to Other Motorcycle?
The 2021 Harley-Davidson FLFBS sits in the modern muscle cruiser segment, directly competing with models that blend aggressive styling with potent performance. Key rivals include the Indian Chief Dark Horse and select models from brands like Ducati (Diavel) or Triumph (Scrambler 1200, though a different style).
Performance: The FLFBS's Milwaukee-Eight 114 engine delivers strong torque and a satisfying rumble, offering brisk acceleration and capable highway cruising. The Indian Chief Dark Horse, with its Thunderstroke 116 engine, often boasts slightly more displacement and torque, providing a comparable, if not more potent, power delivery. The Ducati Diavel offers significantly higher performance with its sportbike-derived engine, but at a much higher price point and with a very different riding dynamic.
Features: The FLFBS comes with modern essentials like LED lighting and ABS. The Indian Chief Dark Horse offers a similar feature set, sometimes including more integrated tech like a touch screen display depending on the specific trim. Ducati Diavel models often lead in technological integration and premium components.
Reliability: Harley-Davidson has a generally good reputation for the reliability of its Milwaukee-Eight engines and Softail platform, especially with proper maintenance. Indian motorcycles have also improved significantly in reliability over the years. Ducati, while offering incredible performance, historically has had a reputation for higher maintenance costs and potentially more complex issues.
Price: The FLFBS is competitively priced within its segment, typically starting in the low $20,000s. The Indian Chief Dark Horse often aligns closely in price. The Ducati Diavel is usually in a higher price bracket, reflecting its performance-oriented engineering and premium branding.
Recommendations:
* Similar Alternative: The Indian Chief Dark Horse is a very strong contender. It offers a similar aggressive aesthetic, powerful V-twin engine, and a robust feature set, often at a comparable price. The choice between them often comes down to brand loyalty and subjective styling preferences.
* For more performance: If raw speed and cutting-edge technology are paramount, and budget is less of a concern, the Ducati Diavel is a superior performer, though it sacrifices some of the classic cruiser feel for a more aggressive, sporty stance.
* For a more classic vibe with modern tech: Some might consider a Triumph Bonneville Bobber or Speedmaster for a different take on the bobber style, though performance is generally less aggressive than the FLFBS.

Whether it's worth buying depends on individual priorities. For its price point, it offers a compelling package of performance, style, and the iconic Harley-Davidson experience. Buying used is often a smart move, as you can find well-maintained examples at a significant discount from their new price, especially a year or two after release, as the initial depreciation has occurred. While new offers the latest options and full warranty, a used 2021 FLFBS can provide excellent value. There is only one primary trim for the Fat Bob, so focusing on condition and mileage for used purchases is key.
