Of course, here is a full article about the 2017–2024 Harley-Davidson Touring FLHX Street Glide, written in the requested style.
The 2017–2024 Harley-Davidson Touring Milwaukee-Eight 107 (FLHX Street Glide) represents a significant era for one of the most iconic models in the American manufacturer’s lineup. Serving as the quintessential “hot-rod bagger,” the Street Glide from this period is defined by the introduction of the Milwaukee-Eight engine, a completely new V-Twin design that brought modern performance, improved rider comfort, and enhanced refinement to the venerable Touring platform. This generation solidified the Street Glide’s position as a market leader by blending its signature stripped-down styling with major technological and mechanical advancements.
Transition from the Twin Cam Engine
The most substantial change for the 2017 model year was the replacement of the long-serving Twin Cam 103 engine with the new Milwaukee-Eight 107. This transition addressed key areas for improvement and marked a clear departure in engineering philosophy.
Valvetrain: The Milwaukee-Eight features four valves per cylinder (totaling eight, hence the name), compared to the Twin Cam’s two valves per cylinder. This improves airflow, resulting in more power, torque, and better fuel efficiency.
Vibration and Smoothness: A key innovation was the inclusion of a single internal counter-balancer. While the Twin Cam engines were known for their signature “Harley shake” at idle, the Milwaukee-Eight’s counter-balancer eliminates 75% of the primary vibration. This results in a much smoother experience at a standstill and while cruising, reducing rider fatigue without erasing the classic V-Twin pulse at speed.
Heat Management: Rider comfort was a major focus. The Milwaukee-Eight engine was designed to run cooler, with improved heat rejection from areas around the rider’s legs, a common complaint on previous models. This was achieved through precision oil cooling targeted at the hottest areas around the exhaust valves.
* Mechanical Simplicity:** The Milwaukee-Eight returned to a single, chain-driven camshaft design, reminiscent of earlier Harley-Davidson engines, which is mechanically simpler than the dual-cam setup of its predecessor.
Engine and Performance: The 2017–2024 Harley-Davidson Touring Milwaukee-Eight 107 (FLHX Street Glide)
The heart of the FLHX Street Glide from this period is the Milwaukee-Eight 107, displacing 107 cubic inches (1,746 cc). This air- and precision oil-cooled 45-degree V-Twin was engineered to deliver stronger low-end torque and a broader, more accessible powerband. Paired with a six-speed Cruise Drive transmission, it provides ample power for city cruising, highway passing, and two-up touring. The engine’s character is defined by a smoother power delivery and a distinct, deeper exhaust note compared to the Twin Cam.
Complementing the new engine was a completely overhauled suspension system. The front features Showa Dual Bending Valve (SDBV) forks, which provide the performance of a racing-style cartridge fork but with linear damping characteristics for a more controlled and comfortable ride. The rear suspension was upgraded to emulsion-style shock absorbers with a tool-free, knob-operated preload adjuster, allowing riders to easily adapt the suspension for a passenger or luggage without needing special tools.
Braking is handled by Reflex Linked Brembo brakes, with ABS offered as a popular option and later becoming standard on many models. This system links the front and rear brakes to provide optimal braking force to each wheel, regardless of which brake control the rider activates, enhancing safety and stability.
Styling, Features, and Evolution
The FLHX Street Glide maintained its signature aesthetic throughout this generation. Key styling cues include the iconic “batwing” fairing mounted to the forks, a low-profile windscreen, a clean rear fender, and sleek, lockable hard saddlebags. The single-piece, two-up seat and low seat height contribute to the bike’s slammed, custom look while offering reasonable comfort for both rider and passenger.
Inside the fairing, the Street Glide featured a modern infotainment system. Early models came standard with the Boom! Box 4.3 system, with the larger, full-color touchscreen Boom! Box 6.5GT available as an upgrade. In 2019, this was updated to the more advanced Boom! Box GTS infotainment system, which offered a faster interface, higher resolution, and smartphone integration through Apple CarPlay.
Over its production run, the model saw incremental updates. These included new paint and wheel options annually. Later in the cycle, Harley-Davidson introduced the optional Reflex Defensive Rider Systems (RDRS), a suite of electronic aids including cornering-enhanced ABS, traction control, and drag-torque slip control, further elevating the bike’s technological capabilities.
