Aluminum Wheel Maintenance
SXS1000M5D (Aluminum wheel model)
Refer to Safety Precautions on page 111.
Aluminum may corrode from contact with dirt, mud, or road salt.
Clean the wheels after riding through any of these substances. Use
a wet sponge and mild detergent. Avoid stiff brushes, steel wool, or
cleaners containing abrasives or chemical compounds.
After washing, rinse with plenty of water and dry with a clean cloth.
Then apply a mild, commercially available spray cleaner/polish or
wax.
For stained or dull-looking wheels, use a quality chrome/aluminum
polish to restore the finish.
