The sixth gear was introduced on Harley-Davidson® motorcycles as a way to improve the overall riding experience. One of the main benefits of adding a sixth gear is increased fuel efficiency. With the ability to run at a higher gear ratio, the engine is able to run at a lower RPM, which reduces fuel consumption. This can result in significant savings for long-distance riders, as well as a reduction in emissions.
In addition to fuel efficiency, the sixth gear also helps to reduce rider fatigue on long trips. When riding at highway speeds, the engine is able to run at a more relaxed pace, allowing the rider to maintain a more comfortable cruising speed without having to constantly shift gears. This can make a big difference over the course of a long journey, as it allows the rider to relax and enjoy the ride.
Another benefit of the sixth gear is improved handling and stability at high speeds. With the ability to run at higher gear ratios, the bike is able to maintain a more consistent speed, which can make it easier to handle in windy conditions or when passing other vehicles. This can also result in a safer riding experience, as the rider is better able to maintain control of the bike at high speeds.
Finally, the sixth gear helps to reduce engine noise and vibration, making for a more comfortable riding experience. With the engine running at a lower RPM, there is less mechanical noise, which can be beneficial for riders who are sensitive to engine noise. Additionally, with less vibration, the rider is less likely to experience fatigue or discomfort.
Overall, the addition of the sixth gear on Harley-Davidson® motorcycles was a significant improvement that has greatly enhanced the riding experience for many riders. It provides a more efficient and comfortable ride, improves handling and stability, and it also reduces engine noise and vibration.
