The 2019–2024 Harley-Davidson Touring Milwaukee-Eight 114 (FLHTK Ultra Limited) represents a pinnacle of the company’s Grand American Touring line, designed for long-distance comfort, performance, and luxury. This generation of the Ultra Limited is defined by the integration of the powerful Milwaukee-Eight 114 engine and a suite of modern technologies, solidifying its position as a flagship model. It builds upon Harley-Davidson’s long heritage of two-up touring machines, offering riders and passengers a premium experience with robust power, advanced rider aids, and comprehensive infotainment options.
Engine and Performance
At the core of the FLHTK Ultra Limited is the Milwaukee-Eight 114 engine, a 45-degree V-twin with a displacement of 114 cubic inches (1,868 cc). This powerplant was a significant step forward for Harley-Davidson, featuring four valves per cylinder (totaling eight, hence the name), a single chain-driven camshaft, and dual spark plugs per cylinder. A key design feature is the internal counter-balancer, which cancels out 75% of the engine’s primary vibration at idle, resulting in a much smoother experience for the rider, especially at stops and during low-speed maneuvers.
The engine is precision oil/air-cooled, focusing on cooling the exhaust valve areas of the cylinder heads to manage heat effectively during long rides and in heavy traffic. This system contributes to consistent performance and enhanced rider comfort. Paired with a 6-speed Cruise Drive transmission, the Milwaukee-Eight 114 delivers substantial torque at low RPMs, providing strong acceleration for passing and climbing grades, even when fully loaded with a passenger and luggage.
Differences from the Previous Twin Cam Engine
The Milwaukee-Eight engine marked a considerable evolution from its predecessor, the Twin Cam engine, which powered earlier Touring models. Key differences include:
Smoother Operation: The single internal counter-balancer in the Milwaukee-Eight dramatically reduced idle vibration, a common characteristic of the non-balanced Twin Cam.
Improved Heat Management: The targeted oil cooling was more efficient at dissipating heat from the rider and passenger compared to the Twin Cam’s less-focused cooling system.
Increased Power and Efficiency: With its 4-valve heads, the Milwaukee-Eight offered improved airflow, resulting in approximately 10% more torque and better fuel economy than the Twin Cam 103 it replaced.
Refined Sound: While retaining a characteristic Harley-Davidson rumble, the Milwaukee-Eight has a mechanically quieter valvetrain, allowing the exhaust note to be more prominent.
Chassis and Handling
The FLHTK Ultra Limited is built on Harley-Davidson’s robust Touring frame, engineered for stability and predictable handling on highways and winding roads. The front suspension features 49mm forks with dual bending valve technology, which provides the performance of a cartridge-style fork with linear damping characteristics for a controlled and comfortable ride. The rear suspension consists of premium emulsion-style shocks, with a single knob for hydraulically adjusting preload without the need for tools, making it easy to adapt the ride for a passenger or heavy luggage.
Braking is handled by the Reflex Linked Brembo brake system with standard ABS. This system electronically links the front and rear brakes to apply the optimal amount of braking power to each wheel, regardless of which brake control the rider uses, enhancing control in urgent braking situations.
Technology and Features of the Harley-Davidson Touring Milwaukee-Eight 114
This generation of the Ultra Limited is equipped with a comprehensive suite of modern technology. The centerpiece is the Boom! Box GTS infotainment system, which features a full-color touchscreen that is usable even with gloves on. The system offers navigation, communication, and music options, with compatibility for Apple CarPlay.
Beginning in 2020, the model became available with the optional, and later standard, Reflex Defensive Rider Systems (RDRS). This advanced package of electronic aids utilizes the latest chassis control, electronic brake control, and powertrain technology to assist the rider in accelerating and braking, especially in adverse conditions. RDRS includes:
Cornering Enhanced ABS (C-ABS): Prevents wheels from locking under braking, even when cornering.
Cornering Enhanced Traction Control System (C-TCS): Prevents the rear wheel from excessive spinning under acceleration in straight lines or corners.
Drag-Torque Slip Control System (DSCS): Manages rear-wheel slip during deceleration.
* Vehicle Hold Control (VHC):** Applies brake pressure to prevent the motorcycle from rolling when stopped on an incline.
Comfort is paramount on the Ultra Limited, which comes standard with heated handgrips, electronic cruise control, a full Batwing fairing with a Splitstream air vent to reduce head buffeting, and a Tour-Pak luggage carrier with an integrated passenger backrest and room for two full-face helmets.
