Of course. Here is a full article about the 2017–2024 Harley-Davidson Police Milwaukee-Eight 114 (FLHP Road King), written in the requested style and format.
The 2017–2024 Harley-Davidson Police Milwaukee-Eight 114 (FLHP Road King) is a purpose-built law enforcement motorcycle produced by Harley-Davidson for use by police departments and government agencies across North America and select international markets. Based on the civilian FLHR Road King platform, the FLHP is factory-equipped with a host of modifications designed to meet the rigorous demands of patrol duty. Its introduction in 2017 marked a significant engineering evolution for Harley-Davidson’s fleet vehicles, primarily due to the replacement of the long-serving Twin Cam engine with the then-new Milwaukee-Eight powerplant.
Development and Transition from the Twin Cam
The development of the Milwaukee-Eight equipped police models was part of a larger update to Harley-Davidson’s entire touring motorcycle lineup. The preceding police model, which ran until 2016, was powered by the Twin Cam 103 engine. While a reliable and proven engine, the Twin Cam was known for producing significant heat and vibration, factors that could increase rider fatigue during long patrol shifts.
The transition to the Milwaukee-Eight 114 engine for the 2017 model year addressed these issues directly. Key differences from the previous Twin Cam 103 model include:
Engine Performance: The Milwaukee-Eight 114 offered a substantial increase in torque and smoother power delivery, providing improved acceleration for traffic enforcement and pursuit situations.
Reduced Vibration: A single internal counter-balancer reduced idle vibration by approximately 75%, leading to greater rider comfort.
Improved Heat Management: The new engine featured precision oil or water cooling targeting the hottest areas around the exhaust valves, significantly reducing the amount of heat felt by the rider, especially in slow-moving traffic.
Upgraded Suspension: The 2017 models introduced all-new front and rear suspension components, featuring Showa Dual Bending Valve (SDBV) technology in the front forks and emulsion-style rear shock absorbers. This provided a more controlled and comfortable ride compared to the previous air-adjustable suspension.
These enhancements made the new FLHP a more capable and comfortable vehicle, allowing officers to perform their duties more effectively and with less physical strain.
Engine and Drivetrain of the Police Milwaukee-Eight 114
At the core of the FLHP is the Milwaukee-Eight 114 engine, a 45-degree V-Twin with a displacement of 114 cubic inches (1868cc). The engine is characterized by its four-valve-per-cylinder heads (totaling eight valves, hence the name), which improves intake and exhaust flow for increased power and fuel efficiency. It is paired with Harley-Davidson’s 6-speed Cruise Drive transmission, which provides smooth shifting and a low final-drive ratio for relaxed highway cruising. Power is delivered to the rear wheel via a quiet and low-maintenance belt drive system.
Chassis and Police-Specific Modifications
The FLHP is built on Harley-Davidson’s robust touring frame, designed for stability at high speeds and maneuverability in urban environments. The updated suspension system provides a compliant ride over varied road surfaces while maintaining firm handling characteristics. Braking is handled by a Reflex Linked Brembo brake system with standard ABS, which electronically links the front and rear brakes to provide optimal braking force under various conditions.
To accommodate the needs of law enforcement, the FLHP includes several features not found on the civilian model:
High-Output Charging System: A powerful alternator and electrical system are standard to support the continuous power draw from emergency lights, sirens, radios, and other police equipment.
Specialized Hand Controls: The switchgear is modified to include controls for sirens and lights, allowing the officer to operate essential equipment without removing their hands from the handlebars.
Solo Saddle: The motorcycle is equipped with a sprung, air-adjustable solo saddle designed for all-day comfort for a single rider in full duty gear.
Factory Pre-Wiring: The FLHP comes with a factory-installed wiring harness that simplifies the process of upfitting the motorcycle with department-specific communication and emergency equipment. This “pigtail” harness reduces installation time and ensures electrical system integrity.
Reinforced Luggage Rack:** A heavy-duty rear rack is fitted to support the weight of police radio equipment. The motorcycle can be equipped with traditional hard-shell saddlebags for storage.
