All Harley-Davidson motorcycles have their engines positioned on the right side. This design feature is commonly referred to as a "right-side drive." It is a distinctive characteristic of Harley-Davidson motorcycles and has been a part of their design for many years.
The right-side drive configuration means that the primary drive, which transfers power from the engine to the transmission, is located on the right side of the motorcycle. The final drive, which delivers power to the rear wheel, is located on the left side. This design choice gives Harley-Davidson motorcycles a unique look and sound.
It's worth noting that other motorcycle manufacturers, such as Indian Motorcycle and most Japanese motorcycle brands, typically have their engines positioned on the left side. Each manufacturer has its own design philosophy and engineering considerations when it comes to motorcycle design.
