210 MAINTENANCE AND ADJUSTMENT Chrome and Aluminum Chrome and uncoated aluminum parts can be treated with a chrome/aluminum polish. Coated aluminum should be washed with a mild neutral detergent and finished with a spray polish. Aluminum wheels, both painted and unpainted can be cleaned with special non-acid based wheel spray cleaners. Leather, Vinyl, and Rubber If your motorcycle has leather accessories, special care must be taken. Use a leather cleaner/treatment to clean and care for leather accessories. Washing leather parts with detergent and water will damage them, shortening their life. Vinyl parts should be washed with the rest of the motorcycle, then treated with a vinyl treatment. The sidewalls of tires and other rubber components should be treated with a rubber protectant to help prolong their useful life. WARNING Rubber protectants can be slippery and, if used on the tread area, cause loss of traction resulting in accident causing injury or death. Do not apply rubber protectant to any tread area.
