The final drive system employed on most Harley-Davidson motorcycles utilizes a reinforced belt to transmit power from the transmission to the rear wheel. This system offers a quieter and smoother ride compared to chain drives, requiring less frequent adjustments and lubrication. A typical example consists of a toothed belt made of a durable, composite material reinforced with aramid fibers, riding on pulleys connected to the output shaft of the transmission and the rear wheel hub.
This method of power transmission contributes significantly to the riding experience characteristic of these motorcycles. Reduced noise and vibration enhance rider comfort, especially on long journeys. Lower maintenance demands simplify ownership and contribute to the longevity of the drivetrain. While belt drives have been a feature of certain models for decades, continuous improvements in materials and design have increased their strength and reliability, making them a staple in the brand’s lineup.
