2017–2024 Harley-Davidson Touring Milwaukee-Eight 107 (FLHR Road King)

Of course. Here is a full article about the 2017–2024 Harley-Davidson Touring Milwaukee-Eight 107, focusing on the FLHR Road King model.

Valvetrain: The Milwaukee-Eight features four valves per cylinder (totaling eight, hence the name), a significant departure from the Twin Cam’s two-valve design. This improves airflow capacity by 50%, contributing to greater power and torque.
Camshaft Design: The engine returned to a single, chain-driven camshaft, similar to the Evolution engine, simplifying the design compared to the Twin Cam’s dual-cam setup.
Vibration and Idle: A key rider-focused improvement was the inclusion of a single internal counter-balancer. This system cancels 75% of primary vibration at idle, resulting in a much smoother experience at a standstill without eliminating the classic V-twin feel at cruising speeds.
Heat Management: The Milwaukee-Eight was designed to run cooler. Targeted oil or liquid cooling around the hottest parts of the cylinder heads (exhaust valves) significantly reduces the amount of heat felt by the rider and passenger, a common complaint with the air-cooled Twin Cam on hot days or in slow traffic.
Charging System:** The charging system was upgraded to provide 50% more output at idle, better supporting the electrical demands of accessories, heated gear, and modern electronics.

Chassis and Suspension Upgrades

Alongside the new engine, the 2017 Touring models received a complete suspension overhaul. This was the second major update to the chassis, which was originally redesigned in 2009 for improved stability. For 2017, Harley-Davidson introduced new front and rear suspension components to enhance both ride comfort and handling performance.

The front forks were equipped with Showa Dual Bending Valve (SDBV) technology, providing the performance of a racing-style cartridge fork with linear damping characteristics. This results in a more controlled and planted feel, especially over small, sharp bumps. At the rear, the air-adjustable shocks of the previous generation were replaced with modern emulsion-style shock absorbers. The most significant improvement was the new tool-free preload adjustment, which could be set using a single hydraulic knob, allowing riders to easily adapt the suspension for a passenger or luggage without needing an air pump.

The 2017–2024 Harley-Davidson Touring Milwaukee-Eight 107 in the Road King (FLHR) Model

As applied to the FLHR Road King, the Milwaukee-Eight 107 and updated chassis created a motorcycle that was both familiar and vastly improved. The bike’s classic silhouette remained, defined by its massive chrome headlight nacelle, wide handlebars, and tank-mounted speedometer. However, the performance was transformed. The 107 cubic-inch (1746 cc) engine delivered approximately 10% more torque than its predecessor, providing stronger acceleration and passing power.

Over its production run from 2017 to 2024, the FLHR Road King remained largely consistent in its core design. Updates were typically limited to new paint color options each model year. Standard features included Reflex Linked Brembo Brakes with ABS, providing confident stopping power by electronically linking the front and rear brakes when the rider applies significant pressure to either control. The one-touch opening saddlebags and detachable windshield maintained the model’s practical touring credentials.
