There is no specific age limit set by Harley-Davidson for riding their motorcycles. However, the legal age requirements for operating a motorcycle can vary depending on the jurisdiction and the type of license you hold. In most places, you need to be at least 16 or 18 years old to obtain a motorcycle license or endorsement, which allows you to legally ride a motorcycle on public roads.
It's important to familiarize yourself with the laws and regulations regarding motorcycle licensing and age restrictions in your specific location. Additionally, it's always recommended to receive proper training and follow safety guidelines when operating any motorcycle, regardless of your age.
