The final drive system employed on most Harley-Davidson motorcycles utilizes a reinforced belt to transfer power from the transmission to the rear wheel. This system offers a quieter and smoother ride compared to chain drives, while requiring less frequent adjustments and maintenance. A typical example consists of a toothed belt composed of aramid fibers embedded within a durable rubber compound, ensuring strength and flexibility.
This method of power transmission contributes significantly to the riding experience characteristic of these motorcycles. Its durability and low maintenance requirements are valued by riders, and its development represents a significant advancement in motorcycle technology. The shift away from chain drives towards belt drives marked a key point in the brand’s history, enhancing comfort and reliability. Furthermore, the belt drive contributes to the distinct aesthetic associated with these machines.
