No, not all police officers are required to ride Harley-Davidson motorcycles. The choice of motorcycles used by police departments can vary depending on the specific policies and preferences of each department. While Harley-Davidson motorcycles are commonly associated with police departments in some countries, such as the United States, it is not a universal requirement.
Many police departments around the world use a variety of motorcycle brands and models to meet their specific needs. These may include motorcycles from other manufacturers such as BMW, Honda, Kawasaki, Yamaha, and others. The selection of a particular brand or model of motorcycle is typically based on factors like performance, reliability, maintenance costs, and the specific requirements of the police department.
It's worth noting that the use of motorcycles by police departments can also vary depending on the type of law enforcement duties involved. Some departments may predominantly use motorcycles for traffic enforcement and patrol, while others may focus more on cars or a combination of vehicles.
Therefore, while Harley-Davidson motorcycles are often associated with police work, they are not the exclusive or mandatory choice for all police officers. Different departments have the flexibility to choose motorcycles that best suit their operational needs and budgetary considerations.
