Harley-Davidson’s new Screamin’ Eagle Stage IV Milwaukee 8 Crate Motor with a whopping 135 cubic inch (2.2 liters using the metric system) displacement. That’s larger than many modern car engines. What all those cubic inches gets you is 144 horsepower and 149 foot-pounds of torque. Better still, those figures are measured at the rear wheel, not just unburdened at the crankshaft. The 2024 Street Glide is more powerful, lighter, and more dynamic, and feature all-new visual design elements that combine a cohesive dynamic flow from the front fenders to the saddlebags. Both models feature an evolved fairing profile that appears refreshingly modern yet retains Harley-Davidson design DNA that makes them instantly familiar. Additional key features include:* An updated Milwaukee-Eight 117 V-Twin engine features a new cooling system which further optimizes thermal comfort for the rider and enhanced intake and exhaust flow to boost performance.* Selectable Ride Modes – Road, Sport, Rain and Custom – electronically control the performance characteristics of the motorcycle.* Infotainment technology is powered by Skyline OS and presented on a 12.3-inch TFT color touch screen that replaces all analog instrumentation and most switches. A new 200-watt audio amplifier powers a pair of fairing-mounted speakers.* Improved aerodynamics enhance rider comfort and reduce subjective helmet buffeting at highway speed by an average of 60 percent. Rear suspension travel is increased to 3-inches. A redesigned one-piece seat shape and padding materials offer a significant improvement in long-range comfort for most riders.The engine in question is Harley-Davidson’s new Screamin’ Eagle Stage IV Milwaukee 8 Crate Motor with a whopping 135 cubic inch (2.2 liters using the metric system) displacement.
