Rim tape is a protective strip applied to the inner surface of a motorcycle wheel rim. Its primary purpose is to shield the inner tube or tire from sharp edges, spoke nipples, and other potential sources of damage. Rim tape also helps to prevent punctures and improve the overall safety and longevity of the wheel assembly. It is usually made from materials like rubber or adhesive-backed fabric and is designed to fit snugly within the rim, covering the spoke holes and providing a smooth surface for the tire or tube.
