The 2017 Harley-Davidson FLS, often known as the Softail Slim, is a cruiser motorcycle that pays homage to post-WWII bobber styling. Introduced in 2012, it was produced until 2017. Its minimalist aesthetic, low-slung profile, and classic charm made it a popular choice for riders seeking an authentic vintage look. Pricing for a new 2017 model ranged from approximately $16,000 to $17,000.
The Good

The FLS offers a timeless, classic design that appeals to the heart, coupled with a comfortable, laid-back riding position for practical enjoyment. Its strong V-twin engine provides satisfying power, while Harley-Davidson's reputation for build quality suggests good long-term reliability.

The Bad

Potential buyers should be aware of the FLS's basic suspension, which can be firm over rough roads. Also, the lack of modern electronic rider aids means a more raw, less forgiving riding experience. Limited storage is another consideration.

2017 Harley-Davidson FLS: Quick Overview

  • Engine: The 2017 Harley-Davidson FLS Softail Slim is powered by a single engine option: the Twin Cam 103B V-twin engine. This air-cooled engine displaces 1690cc (103 cubic inches).
  • Horsepower: While Harley-Davidson typically doesn't officially state horsepower figures, the Twin Cam 103B is estimated to produce around 70-75 horsepower at the crank. Torque is its strong suit, with figures typically around 97-100 lb-ft.
  • Fuel Economy: The fuel economy for the 2017 FLS is generally in the range of 42-45 miles per gallon (MPG), depending on riding style and conditions.

What Problems Does the 2017 Harley-Davidson FLS Have?

The 2017 Harley-Davidson FLS, as part of the Softail family and utilizing the Twin Cam 103B engine, generally enjoys a reputation for solid reliability, especially when properly maintained. However, like any motorcycle, there are common points to consider. One frequently reported aspect across Twin Cam models, including the 2017 FLS, involves the cam chain tensioners. Early Twin Cam engines used plastic cam chain tensioner shoes that could wear down over time, leading to a rattling noise and potential failure. While Harley-Davidson updated these components throughout the Twin Cam's lifespan, it's a common area of concern for owners and a point of inspection for potential buyers. For the 2017 model year specifically, there were a few recalls issued for Harley-Davidson motorcycles. One significant recall involved the clutch master cylinder, where a small number of units could have a faulty seal, potentially leading to a loss of clutch function. Another recall addressed potential issues with the throttle control system. While these recalls were addressed by Harley-Davidson, it's crucial for any owner or prospective buyer to verify that all applicable recalls have been performed on the specific vehicle. Beyond these specific recalls, long-term reliability is largely dependent on the owner's maintenance habits. Regular oil changes, proper lubrication, and timely servicing of wear items like brake pads and tires are essential. Owners who neglect maintenance may encounter issues sooner. Some riders report that the stock suspension, particularly the rear shocks, can feel a bit basic and may become harsher with age and mileage, but this is more of a comfort and performance characteristic than a reliability failure. Overall, the 2017 FLS is considered a robust machine, but vigilance regarding recalls and diligent maintenance are key to ensuring its long-term dependability.

How long will the 2017 Harley-Davidson FLS last?

With proper and consistent maintenance, a 2017 Harley-Davidson FLS can reasonably be expected to last for well over 100,000 miles, with many owners reporting their Twin Cam-powered Harleys exceeding 150,000 miles. The core engine and transmission are built for longevity. The primary weaknesses over time tend to be cosmetic wear, such as fading paint or tarnishing chrome, and the eventual need for suspension component replacement due to wear and tear, especially if subjected to rough roads. The previously mentioned cam chain tensioners are a long-term check item. However, the fundamental mechanicals of the Twin Cam 103B are known for their robustness, making the FLS a durable machine if treated well.

What Technology & Safety Features are Included?

The 2017 Harley-Davidson FLS Softail Slim is intentionally designed with a focus on classic styling, which means its technology suite is intentionally minimalist, eschewing the complex electronics found on many modern motorcycles. There is no built-in infotainment system or advanced entertainment features. The rider interface is primarily a single analogue speedometer with an integrated digital odometer and gear indicator. Navigation and music would require aftermarket solutions. In terms of driver-assistance features, the 2017 FLS does not offer features like traction control, multiple riding modes, or electronic cruise control as standard. However, Anti-lock Braking System (ABS) was an available factory option and is highly recommended for enhancing safety. It's crucial to check if a specific FLS is equipped with ABS, as it significantly improves braking control, especially in emergency situations or on slippery surfaces. Safety features beyond the optional ABS are focused on the fundamental aspects of motorcycle design: reliable brakes, good lighting, and a sturdy chassis. Due to the nature of motorcycle testing, official crash-test ratings like those for cars are not applicable or available for the 2017 Harley-Davidson FLS. Safety is primarily left to the rider's skill, the motorcycle's inherent stability, and the availability of optional safety systems like ABS. For riders seeking advanced technological integration, the FLS might feel basic, but for those who appreciate a pure, analog riding experience, its simplicity is a key part of its appeal. The focus is on the connection between rider, machine, and the road, rather than digital distractions.

2017 Harley-Davidson FLS Prices and Market Value

When new, the 2017 Harley-Davidson FLS Softail Slim typically retailed between $16,000 and $17,000 USD, depending on color options and any dealer-installed accessories. On the used market in late 2023 and early 2024, prices generally range from $10,000 to $14,000, with variations based on mileage, condition, maintenance history, and the presence of desirable factory options like ABS. Harley-Davidson motorcycles, especially popular models like the Softail Slim, tend to hold their value relatively well compared to many other brands. Depreciation is most significant in the first few years of ownership. Factors positively affecting resale value include low mileage, excellent maintenance records, original paint and parts, and any desirable factory options. Conversely, significant modifications, high mileage, or a lack of service history can decrease its market value.

2017 Harley-Davidson FLS Cost of Ownership

Owning a 2017 Harley-Davidson FLS is generally considered moderately costly, leaning towards the pricier side of motorcycle ownership. Insurance premiums can vary significantly based on rider age, location, and driving record but are typically higher than for smaller, less powerful bikes. Fuel costs are reasonable, with its V-twin engine achieving around 42-45 MPG. Maintenance is crucial; while routine oil changes and inspections are manageable, parts and specialized labor from Harley-Davidson dealerships can be expensive. Repairs, especially for complex issues, can also add up. It's not an economical daily commuter but offers value for its style and brand prestige, with long-term ownership costs reflecting its premium nature.

How Does the 2017 Harley-Davidson FLS Compare to Other Motorcycle?

The 2017 Harley-Davidson FLS Softail Slim competes in the cruiser segment, directly challenging models like the Indian Scout Bobber and various Japanese cruisers such as the Honda Shadow series or Yamaha Bolt. In terms of performance, the FLS's Twin Cam 103B engine offers strong low-end torque, ideal for cruising and relaxed acceleration, though it's not built for outright speed or high-RPM performance. The Indian Scout Bobber, with its liquid-cooled V-twin, often provides a more potent and modern power delivery. Features on the FLS are deliberately sparse, focusing on its retro aesthetic with minimal technology. Rivals like the Yamaha Bolt offer a similar minimalist vibe but might include slightly more modern instrumentation. Reliability is generally good for the Harley, though the Twin Cam has known points like cam tensioners. Indian has improved its reliability significantly, while Japanese brands are typically paragons of mechanical dependability. Price-wise, the FLS often sat in a premium position when new. Used, it remains competitive, but the Indian Scout Bobber might offer a newer platform or more features for a similar used price. Alternatives worth considering include the Indian Scout Bobber for a more modern take on the bobber style with a punchier engine, or the Yamaha Bolt R-Spec for a more budget-friendly, customizable Japanese cruiser with a similar stripped-down appeal. If pure reliability and potentially lower maintenance costs are paramount, a Honda Shadow Phantom or a Kawasaki Vulcan S could be considered, though they lack the distinct Harley-Davidson character and bobber styling of the FLS.

Final Verdict: Is the 2017 Harley-Davidson FLS a Good Motorcycle?

The 2017 Harley-Davidson FLS Softail Slim is ideal for riders who appreciate classic, minimalist bobber styling and the iconic Harley-Davidson experience. It's perfect for those who prioritize a laid-back cruising style over aggressive performance or cutting-edge technology. It's worth buying for enthusiasts drawn to its vintage aesthetics and the satisfying torque of the Twin Cam 103B engine. Purchasing used is the only option now, and it's a good value if found in good condition with documented maintenance and ideally, ABS. It represents a solid choice for a stylish cruiser with timeless appeal, provided the buyer understands its retro nature and isn't seeking a high-tech, feature-laden machine.
