2018–2024 Harley-Davidson Softail Milwaukee-Eight 114 (FLHCS Heritage Classic 114)

Of course. Here is a full article based on your topic and requirements.

Engine: The most significant change was the move from the air-cooled Twin Cam 103B engine to the new Milwaukee-Eight 114. The Milwaukee-Eight features four valves per cylinder, a single chain-driven camshaft, and dual internal counter-balancers. This resulted in a smoother, more refined engine with significantly more torque and horsepower, improved heat management, and a distinct exhaust note.
Chassis: The old Softail frame, known for its twin shocks hidden underneath the transmission, was completely replaced. The new frame is a stiffer, lighter monoshock design that uses a single, easily adjustable coil-over shock located beneath the seat. This new architecture dramatically improved handling dynamics, increased lean angles, and reduced overall vehicle weight by over 30 pounds (14 kg) compared to its predecessor.
Styling and Features:** While maintaining its classic full-fendered, studded-leather look, the new generation adopted a darker, more modern aesthetic. The abundant chrome of the previous model was replaced with blacked-out components, including the engine, forks, and console. The windshield became detachable, and the classic leather saddlebags were redesigned to be more rigid, lockable, and weather-sealed, enhancing their practicality for touring.

The Heritage Classic 114 and the Milwaukee-Eight Engine

At the heart of the FLHCS is the Milwaukee-Eight 114 V-twin engine. Displacing 114 cubic inches (1868cc), this engine was engineered to deliver massive low-end torque, providing strong acceleration from a standstill and ample passing power on the highway. Within the Softail frame, the engine is rigid-mounted and utilizes dual counter-balancers, which cancel out primary vibrations at idle and allow the rider to feel the engine’s character at speed without excessive shaking. This balance makes the Heritage Classic 114 comfortable for long-distance touring while still delivering the visceral feel expected of a Harley-Davidson V-twin. The engine is paired with a 6-speed Cruise Drive transmission, ensuring relaxed RPMs at highway speeds.

Chassis, Suspension, and Handling

The updated Softail frame provides a more responsive and engaging ride. The front suspension features a Showa dual-bending valve (DBV) fork, which offers the performance characteristics of a cartridge-style fork but with linear damping for a more controlled ride over various road surfaces.

The rear monoshock suspension is a key component of the new chassis. It preserves the classic “hardtail” look that defines the Softail family but provides a modern, compliant ride. Preload can be adjusted to accommodate a passenger or luggage, allowing the rider to fine-tune the handling and comfort level without special tools. Combined with the frame’s increased stiffness, these suspension components give the Heritage Classic 114 confidence-inspiring stability in corners and a smoother experience on long stretches of road. Standard features like full-sized rider floorboards, a comfortable two-up seat, and standard cruise control further solidify its role as a capable light-touring machine.
