Of course. Here is a full article about the 2017–2019 Harley-Davidson Touring FLHTKL Ultra Limited Low, written in the requested style and format.
The 2017–2019 Harley-Davidson Touring Milwaukee-Eight 107 (FLHTKL Ultra Limited Low) represents a significant generation in the company’s long history of grand American touring motorcycles. Launched as part of the 2017 model year lineup, this model introduced the then-new Milwaukee-Eight engine to the public while specifically catering to riders seeking a more manageable and confidence-inspiring fit on a full-featured touring machine. It combined the long-haul amenities of the Ultra Limited with ergonomic enhancements designed to bring the controls, and the ground, closer to the rider.
The Advent of the Milwaukee-Eight Engine
The most substantial update for the 2017 model year was the replacement of the long-serving Twin Cam engine with the new Milwaukee-Eight. This was the ninth generation of Harley-Davidson’s “Big Twin” engine and represented a major leap forward in performance, rider comfort, and emissions compliance.
The Milwaukee-Eight 107 (107 cubic inches / 1753 cc) featured four valves per cylinder—totaling eight valves, hence the name—which significantly improved intake and exhaust flow efficiency by 50% over the previous Twin Cam models. This resulted in a noticeable increase in torque and power across the RPM range.
Key Differences from the Twin Cam Predecessor
Compared to the Twin Cam engine it replaced, the Milwaukee-Eight brought several key improvements designed to enhance the riding experience:
Reduced Vibration: A single internal counter-balancer was engineered to cancel 75% of the engine’s primary vibration at idle. This resulted in a much smoother experience at a standstill, while still retaining the classic Harley-Davidson feel when underway.
Improved Heat Management: The engine was designed for better heat dissipation, a common concern on the previous air-cooled Twin Cam. The FLHTKL utilized the “Twin-Cooled” version of the Milwaukee-Eight, which used liquid coolant circulated through the cylinder heads to further reduce heat felt by the rider and passenger, especially in slow-moving traffic.
Enhanced Power and Response: The four-valve-per-cylinder design, coupled with dual spark plugs per cylinder, provided quicker throttle response and more passing power. The engine produced approximately 10% more peak torque than the Twin Cam 103 it succeeded.
Refined Sound: A richer and more mechanically subdued exhaust note was achieved through lighter valvetrain components, a single-cam design, and optimized cover designs.
Chassis and Ergonomic Design of the FLHTKL Ultra Limited Low
The defining characteristic of the 2017–2019 Harley-Davidson Touring Milwaukee-Eight 107 (FLHTKL Ultra Limited Low) is its ergonomics. Built on Harley’s robust touring frame, the “Low” model incorporated several modifications to accommodate a wider range of riders, particularly those with a shorter inseam.
The front and rear suspension were lowered, resulting in a laden seat height of just 26.6 inches (675 mm), one of the lowest in the full-size touring class. This allowed most riders to comfortably place both feet flat on the ground at a stop. To complement the lower stance, the motorcycle was equipped with a “pull-back” handlebar that brought the grips closer to the rider, reducing reach and shoulder strain. Further adjustments included a narrower primary drive cover and a sculpted, low-profile seat to allow the rider’s legs a straighter path to the pavement.
Onboard Technology and Touring Features
As a premium touring model, the FLHTKL was equipped with a comprehensive suite of features. The centerpiece was the Boom! Box 6.5GT infotainment system, featuring a full-color touchscreen, GPS navigation, and Bluetooth connectivity for hands-free calling and music streaming.
Standard safety features included Reflex Linked Brembo Brakes with ABS. This system electronically links the front and rear brakes to provide optimal braking force to each wheel, regardless of which brake control the rider uses, and prevents wheel lock-up under heavy braking. The bike also featured Daymaker LED headlamps and fog lamps for superior visibility, along with a full Tour-Pak luggage carrier and saddlebags, cruise control, and heated handgrips, making it fully equipped for cross-country travel right from the showroom floor.
