Lowering a Harley Davidson motorcycle can certainly affect the handling. This is because when you lower the bike, you are changing the center of gravity and affecting the suspension. Many people believe that lowering a Harley improves the handling, but it really depends on your individual riding style and preferences. You may find that lowering your bike makes it more difficult to corner at high speeds or navigate through tight turns. If you frequently ride on winding roads or off-road trails, you may want to keep your Harley at its stock height in order to maintain optimal handling. Ultimately, it is up to you to experiment with different settings and find what works best for you and your motorcycle.
