To ride a Harley-Davidson motorcycle, you typically need a regular motorcycle license or endorsement, depending on the requirements of your jurisdiction. The specific license you need may vary from country to country or even state to state, so it's essential to consult the regulations in your particular area.
In the United States, for example, most states require a motorcycle endorsement on your driver's license to legally operate a motorcycle, including Harley-Davidson motorcycles. To obtain a motorcycle endorsement, you generally need to pass a written test that covers motorcycle-specific rules and regulations and demonstrate your riding skills by completing a practical exam.
It's important to check with your local Department of Motor Vehicles (DMV), Driver and Vehicle Licensing Agency (DVLA), or relevant licensing authority to determine the exact requirements for riding a motorcycle, including a Harley-Davidson, in your specific location. They can provide you with the most accurate and up-to-date information regarding licensing and endorsement requirements.
