What Problems Does the 2015 Harley-Davidson FLHTKL Have?
The 2015 Harley-Davidson FLHTKL, while generally a robust touring machine, did have some reported issues and recalls that owners should be aware of. One of the most significant recalls affecting many Harley-Davidson models from this period, including the 2015 FLHTKL, involved the front brake master cylinder. This recall (often referenced as affecting certain production dates) was due to a potential internal seal failure that could lead to a brake lever feeling spongy or a loss of braking power. It was imperative for owners to have this addressed by a dealer.
Another area that sometimes garnered attention was the electronic systems, particularly the infotainment unit, the Boom!™ Box. While offering modern amenities, some users reported occasional glitches with Bluetooth connectivity, touch screen responsiveness, or audio system quirks. These were often software-related and sometimes resolvable with firmware updates, but some instances required dealer intervention.
Regarding the Twin Cam 103™ engine itself, it is generally considered reliable. However, like many air-cooled V-twins, consistent and diligent maintenance is paramount. Owners who neglected regular oil changes, filter replacements, or proper spark plug maintenance might experience accelerated wear or performance degradation. Some users reported minor oil leaks from gaskets over time, which is not uncommon for engines of this design with significant mileage.
The clutch and transmission also generally hold up well, but aggressive riding or improper clutch use can lead to premature wear. For the 2015 model year specifically, while not a widespread epidemic, there were isolated reports of issues with the starter clutch or transmission engagement, particularly with higher mileage examples that may not have received optimal care.
Long-term reliability is heavily dependent on the owner's maintenance habits. Bikes that were regularly serviced according to Harley-Davidson's schedule, with quality fluids and parts, tend to be very durable. Conversely, neglected bikes might encounter more electrical gremlins, premature wear on suspension components, or drive belt issues. The overall consensus is that with proper care, the 2015 FLHTKL is a dependable touring motorcycle, but vigilance regarding recalls and routine maintenance is key.

How long will the 2015 Harley-Davidson FLHTKL last?
Based on owner data and common usage patterns for touring motorcycles like the 2015 Harley-Davidson FLHTKL, it is not uncommon for these bikes to accumulate 50,000 to 100,000 miles or more over their service life. Many owners use them for extensive touring and day-to-day riding. With diligent maintenance, including regular oil changes, filter replacements, and component checks, the Twin Cam 103™ engine is capable of lasting well over 100,000 miles. Key areas to monitor for long-term durability include the drive belt, wheel bearings, suspension components (especially seals), and the exhaust system. While the core engine and transmission are robust, electrical components and accessories like the infotainment system might require more attention as they age. Proper care ensures excellent long-term reliability, making it a trustworthy companion for many years and miles.
What Technology & Safety Features are Included?
The 2015 Harley-Davidson FLHTKL came equipped with a suite of technology and comfort features designed for long-distance touring. The centerpiece of its entertainment system was the Boom!™ Box 4.3 infotainment unit. This system included an AM/FM radio, a USB port for connecting and charging devices, and Bluetooth connectivity for audio streaming and hands-free phone calls. It featured a 4.3-inch color touchscreen display, though its visibility could be reduced in bright sunlight.
Standard safety features included integrated ABS (Anti-lock Braking System) for both the front and rear brakes, providing enhanced stopping power and control, especially in adverse conditions. The linked braking system meant that applying pressure to either brake lever would engage both brakes to some extent, further aiding in stable deceleration. The FLHTKL also came with a standard cruise control system, which is a significant convenience for highway riding, reducing rider fatigue.
For comfort and convenience, the bike featured heated grips to keep hands warm in cooler weather, a comfortable two-up saddle with lumbar support for the passenger, and ample storage in its hard-shell saddlebags and tour-pak.
Optional features available at the time of purchase could have included a CB radio and intercom system for communication with a passenger or other riders, a GPS navigation system (sometimes integrated into the Boom!™ Box or as a separate unit), and various cosmetic and functional accessories.
It's important to note that motorcycles, unlike cars, are not subjected to standardized crash-test ratings by organizations like the NHTSA or IIHS. Safety evaluations for motorcycles typically focus on the effectiveness of individual safety features like ABS, lighting, and chassis integrity under stress. The design of the FLHTKL, with its substantial fairing and stable platform, contributes to rider protection from the elements and offers a degree of stability, but it does not receive a numerical crash-test rating.

2015 Harley-Davidson FLHTKL Prices and Market Value
When new, the 2015 Harley-Davidson FLHTKL Ultra Low carried a premium price tag, typically ranging from approximately $26,000 to over $28,000 depending on color options and any factory-installed accessories. The FLHTKL, as the top-tier Ultra model, represented a significant investment.
Currently, the used market price for a 2015 FLHTKL varies considerably based on mileage, condition, maintenance history, and added accessories. A well-maintained example with average mileage might be found in the $15,000 to $19,000 range. Bikes with significantly lower mileage or desirable upgrades can command higher prices, while those with higher mileage or in lesser condition may fall below this range.
Harley-Davidson motorcycles, especially the touring models, tend to hold their value relatively well compared to many other vehicle types.

2015 Harley-Davidson FLHTKL Cost of Ownership
Owning a 2015 Harley-Davidson FLHTKL is generally considered a moderately costly endeavor, especially compared to smaller motorcycles. Insurance premiums can be substantial due to the bike's value and the potential for theft, varying greatly by rider profile, location, and coverage levels. Fuel economy, while decent for a large V-twin (around 35-40 mpg), means fuel costs will be a notable part of ownership. Maintenance, including regular oil changes, tire replacements, and periodic checks of the drive belt and brakes, requires ongoing investment. Repairs, especially for specialized parts or if significant issues arise, can be expensive, often requiring dealership service. Overall, it's not an economical vehicle to own, but the cost is often offset by the luxury touring experience and brand prestige.
