Original Kymco Spike Chain Tensioner Plug Washer

Washers are small metal or plastic pieces that fit between screws, bolts, and other motorcycle parts. They help prevent unwanted loosening due to vibrations and forces they are exposed to during riding. Properly installed, high-quality washers can last for many years under normal use. However, it's important to watch for any signs of wear or damage and take steps to replace them when necessary to ensure safe and reliable operation.
