A Superbike is a motorcycle used for racing in the "American Motorcycle Assosiation Superbike Challenge".
Spelled with a lowercase 's' it refers to the consumer version of the racing motorcycle.

You could say that, advertising a company name through racing is profitable but,
selling the actual racing bike is more profitable.
