EAU26000 Care While the open design of a motorcy- cle reveals the attractiveness of the technology , it also makes it more vul- nerable. Rust and corrosion can develop even if high-quality compo- nents are used. A rusty exhaust pipe may go unnoticed on a car , however , it detracts from the overall appearan- ce of a motorcycle.
ve any marks. If the windshield is scratched, use a quality plastic polishing compound after washing. After normal use Remove dirt with warm water , a mild deter gent, and a soft, clean sponge, and then rinse thoroughly with clean water . Use a toothbrush or bottle- brush for hard-to-r each areas.
ECA10800 CAUTION ● Apply spray oil and wax spa- ringly and make sure to wipe off any excess. ● Never apply oil or wax to any rubber and plastic parts, but treat them with a suitable car e product. ● Avoid using abrasive polishing compounds as they will wear away the paint.
