The 2010 Harley-Davidson FLSTFB, known as the Fat Boy Lo, is a cruiser motorcycle that debuted in 2010. Part of the Softail family, it distinguished itself with a lower seat height and a more accessible riding position, making it particularly popular for riders seeking classic styling with modern comfort. Its model years primarily fall within the late 2000s to early 2010s, with pricing for a used model typically ranging from $9,000 to $15,000, depending on condition and mileage.
The Good

The 2010 FLSTFB boasts a iconic Harley-Davidson V-twin rumble for emotional appeal, coupled with a low seat height and relaxed ergonomics for exceptional comfort. Its classic styling offers timeless design, while its robust build provides good value for discerning riders.

The Bad

Potential buyers should watch for typical Harley-Davidson quirks like a less potent braking system than modern bikes and the potential for oil leaks on older models. Some riders find the stock suspension could be improved for more aggressive riding.

2010 Harley-Davidson FLSTFB: Quick Overview

  • Engine Options: The 2010 Harley-Davidson FLSTFB primarily came equipped with a 96 cubic inch (1584cc) Twin Cam 96 V-twin engine. This was fuel-injected and air-cooled.
  • Horsepower: Harley-Davidson typically rates its engines in torque rather than horsepower for this era. The Twin Cam 96 produced around 86 lb-ft of torque at approximately 3000 RPM. Horsepower figures were generally in the mid-60s, but exact official numbers varied.
  • Fuel Economy: Fuel economy for the 2010 FLSTFB is estimated to be around 40-45 miles per gallon (MPG) in combined city and highway riding, though this can vary significantly based on riding style and conditions.
  • 0-60 Times: While not a primary metric for cruisers, acceleration is brisk. 0-60 mph times are generally estimated to be in the 5-6 second range, offering satisfying get-up-and-go for most riders.
  • Towing Capacity: As a motorcycle, the 2010 Harley-Davidson FLSTFB does not have an official towing capacity and is not designed for towing trailers or other vehicles.
  • Trim-Level Features: The FLSTFB was a specific trim within the Softail lineup, distinct for its low seat height and classic styling. Key features included:
    • Low Seat Height: A signature feature, typically around 24.25 inches, making it very accessible.
    • Fat Tires: Chrome-spoked wheels with wide, balloon-style tires, a hallmark of the Fat Boy line.
    • Chrome Accents: Extensive chrome plating on the engine, exhaust, handlebars, and other components.
    • Relocated Instruments: The speedometer was often mounted on the handlebar riser.
    • Forward-Mounted Controls: Contributed to a relaxed riding posture.
    • Disc Brakes: Single disc brakes front and rear, common for the era.
    • ABS: Anti-lock Braking System was an optional feature on some models and is a desirable addition.

What Problems Does the 2010 Harley-Davidson FLSTFB Have?

The 2010 Harley-Davidson FLSTFB, like many motorcycles of its era, is generally considered reliable if well-maintained. However, some common issues and points of concern have been reported by owners over time. One frequently mentioned aspect is the potential for the stock braking system to feel somewhat underpowered, especially when compared to more modern motorcycles or when riding aggressively. This isn't necessarily a 'problem' but rather a characteristic that some riders choose to upgrade. Another area to be mindful of is potential oil leaks, which can sometimes occur with the Twin Cam engines, particularly as they age and mileage increases. Regular checks and proper maintenance can often mitigate or resolve these.

Electrical gremlins, while not epidemic, can occasionally surface. This might manifest as issues with lights, indicators, or dashboard components. Ensuring all electrical connections are clean and secure is important. Another consideration for the Twin Cam 96 engine is the cam chain tensioner. Early versions of the Twin Cam engines had plastic cam chain tensioners that could wear over time and lead to noise or potential damage. While the 2010 model year likely incorporated updated tensioners, it's a point of vigilance for owners. There were some recalls issued for Harley-Davidson motorcycles around this period, though specific recalls for the 2010 FLSTFB might vary. It is crucial for potential buyers to research the VIN of any specific bike they are considering to check for outstanding recalls or past recall work.

Long-term reliability is largely dictated by maintenance. A meticulously maintained FLSTFB can last for hundreds of thousands of miles. Neglecting regular oil changes, filter replacements, and fluid checks will undoubtedly accelerate wear and increase the likelihood of encountering issues. The Softail frame itself is robust, and the drivetrain, when cared for, is known for its longevity. However, it's always wise to inspect for any signs of corrosion, especially on chrome components, and ensure that any aftermarket modifications have been performed correctly and do not compromise the bike's integrity.

How long will the 2010 Harley-Davidson FLSTFB last?

With diligent maintenance, the 2010 Harley-Davidson FLSTFB can realistically achieve well over 100,000 miles, with many owners reporting 150,000 miles or more. The Twin Cam 96 engine is known for its robustness and longevity. Regular oil changes, proper tire inflation, and attentive servicing are paramount. Weaknesses over time primarily revolve around the natural wear and tear of components like wheel bearings, suspension bushings, and the clutch. Chrome can also be susceptible to corrosion if not properly cared for. Electrically, while generally reliable, older bikes can sometimes develop minor issues with switches or connections. The overall durability is high, making it a strong choice for long-term ownership, provided a consistent maintenance schedule is followed.

What Technology & Safety Features are Included?

The 2010 Harley-Davidson FLSTFB, true to its classic cruiser ethos, prioritizes a more analog riding experience, meaning its built-in technology is relatively basic. It doesn't feature advanced infotainment systems or extensive digital displays found on many modern vehicles. The primary 'tech' is functional::

  • Instrumentation: A classic analog speedometer is mounted on the handlebar riser, often with a smaller fuel gauge and indicator lights integrated. It provides essential riding information.
  • Lighting: Standard Halogen headlight and tail lights. Turn signals are typically basic incandescent bulbs.
  • Security: Some models may have come equipped with a factory alarm system and immobilizer, which is a key fob-based security feature. This is a common optional accessory for Harley-Davidsons.
  • Optional ABS: Anti-lock Braking System (ABS) was an available option on the 2010 FLSTFB. This is a significant safety feature that significantly improves braking control in emergency situations and is highly recommended if available.
  • Optional Cruise Control: While not standard on all models, cruise control was an option that enhanced long-distance comfort.


Entertainment is deliberately kept minimal, allowing the rider to focus on the road and the sound of the V-twin engine. There are no built-in audio systems or navigation. Driver-assistance features are virtually non-existent, aligning with its classic design philosophy. Regarding safety, the primary safety features are the brakes and lighting. The bike is equipped with front and rear disc brakes. As a motorcycle, it does not undergo traditional automotive crash-test ratings like cars. Safety is primarily dependent on rider skill, responsible riding practices, and potentially optional safety features like ABS. The robust construction of the Harley-Davidson frame contributes to its inherent stability.

2010 Harley-Davidson FLSTFB Prices and Market Value

Owning a 2010 Harley-Davidson FLSTFB is generally considered moderately costly, leaning towards the higher end for a motorcycle. Insurance premiums can vary significantly based on rider history, location, and coverage, but Harley-Davidsons often command higher rates. Fuel economy is decent for its class, around 40-45 MPG. Maintenance is ongoing; regular oil changes, filter replacements, and scheduled service intervals are crucial for longevity. Repairs can be expensive, especially if specialized Harley-Davidson parts or labor are required. While not economical, the value lies in its iconic status and potential for long-term enjoyment, making it a worthwhile investment for enthusiasts.

2010 Harley-Davidson FLSTFB Cost of Ownership

The 2010 Harley-Davidson FLSTFB, positioned as a low-slung, classic cruiser, competes in a segment populated by other American and Japanese manufacturers. Key rivals from the same era include the Indian Chief Classic (though Indian's resurgence was gaining steam, availability might be less), and various models from Honda (like the Shadow series, though often less powerful and with a different aesthetic), Kawasaki (e.g., Vulcan series), and Yamaha (e.g., V-Star series).

Performance: The FLSTFB's Twin Cam 96 engine offers ample torque for cruising, but its horsepower and acceleration are generally surpassed by some Japanese rivals and more performance-oriented cruisers. Its handling is stable and predictable, ideal for relaxed riding, but less agile than sportier bikes.

Features: Harley-Davidsons historically emphasize classic styling and rider comfort over extensive tech. Compared to some Japanese offerings that might include more standard electronic features or rider aids (even in 2010), the FLSTFB is simpler. The key feature is its iconic design and the signature V-twin rumble.

Reliability: While often perceived as very reliable, modern Japanese cruisers, particularly from Honda and Yamaha, often have a reputation for superior mechanical consistency and lower maintenance needs over the long term. Harley-Davidsons, especially older models, can require more diligent maintenance and may have more quirks.

Price: Used prices for a 2010 FLSTFB typically fall in the $9,000-$15,000 range. Competitors like Yamaha V-Stars or Honda Shadows can often be found at lower price points, offering strong value for a rider on a tighter budget. More premium American rivals, if available, might command higher prices.

Recommendations:
  • Similar Alternative: The Harley-Davidson Softail Deluxe offers a similar platform with more traditional chrome styling and spoked wheels, providing a comparable riding experience.
  • Japanese Alternative (Value/Reliability): For riders prioritizing bulletproof reliability and potentially lower ownership costs, the Yamaha V-Star 1300 or Honda Shadow Phantom/Aero are excellent alternatives, offering comfortable cruising with less mechanical fuss, though with a different aesthetic and engine character.
  • Alternative for More Modern Features: If technology and more contemporary performance are desired, looking at newer models or different classes of bikes would be necessary, as the 2010 FLSTFB is firmly in the classic cruiser category.
