A motorcycle final drive system employing a reinforced belt to transmit power from the transmission to the rear wheel is a common feature on Harley-Davidson motorcycles. This system typically consists of a toothed belt, two pulleys (one at the transmission output and one at the rear wheel), and an adjustable tensioner to maintain proper belt engagement. A common example is the use of a reinforced rubber belt with embedded carbon fiber cords for strength and durability.
This method of power transmission offers several advantages, including quieter operation compared to chain drives, reduced maintenance due to the lack of lubrication requirements, and a cleaner overall aesthetic. Historically, Harley-Davidson adopted this technology to improve rider comfort and enhance the cruising experience. The shift towards these systems also reflects advancements in materials science, enabling the creation of belts capable of withstanding the high torque and power output of these large-displacement engines.
