I have always had black and chrome bikes with the exception of my old Yamahas. I buff them up nice with maguiars when brand new and then use lemon pledge to keep them shiny...then hit the tank with the buffer once a year. If you have never used lemon pledge to clean your bike...try it. Takes all the fingerprints & bugs off. For heavy cleaning I use simple green or S100.
Lemon pledge & a cheap micro fiber towel makes owning a black bike easy.
If you want to wax your bike with a polymer cleaner wax that will last all year try Klasse
