To maintain warranty coverage for your Harley-Davidson motorcycle, it is generally recommended to use genuine Harley-Davidson parts. Harley-Davidson strongly advises using their genuine parts to ensure proper fitment, performance, and compatibility with your specific model.
While it is not always mandatory to purchase parts directly from Harley-Davidson for minor maintenance or accessory additions, using non-genuine parts could potentially void specific warranty claims if the issue is directly related to the use of non-genuine parts or if they are found to have caused damage.
It's crucial to review the specific terms and conditions of your warranty provided by Harley-Davidson or consult with a Harley-Davidson dealership to obtain accurate and up-to-date information regarding warranty coverage and the use of aftermarket parts on your particular motorcycle model.
