Yes, some Harley-Davidson motorcycles are equipped with a reverse gear. Reverse gears are typically found on larger and heavier touring models designed for long-distance riding. These motorcycles are often referred to as "Touring" or "Cruiser" models. The reverse gear is a useful feature that assists riders in maneuvering their motorcycles in tight spaces or when parking, especially given the weight of these larger bikes.
It's important to note that not all Harley-Davidson models have a reverse gear. Reverse functionality is not available on their entire lineup. If reverse capability is a specific requirement, it's advisable to check the specifications of the particular model you are interested in or consult with a Harley-Davidson dealership for accurate information on which models offer reverse gear.
