Superbike 

A hybrid street motorcycle that is highly modified particulary for use racing. This term has been around since circa 1969 and Webster has failed to publish it.

I watched World Superbike racing last night on the Speed channel

superbike 

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.
Yes, the competing manufacturers actualy produce the racing machines to sell to consumers (equiped with turn signals for street use).
You could say that, advertising a company name through racing is profitable but,
selling the actual racing bike is more profitable.

Suzuki GSXR
Kawasaki ZX-R
Honda CBR
Yamaha FZR

superbabe 

A Superbabe is a woman who is delicious in everyway, from head to toe. Her personality is addictive. Her beauty is mesmerizing. Her soul is captivating. A Superbabe can make a man smile in his darkest hour. She can make him melt while flashing her "supersmile". A sexual force to be reckoned with that can lasso a man with her heart.

I was on the phone with Araceli when she superbabed me with the sweetest words I have ever heard. Her Superbabe powers can turn my frown upside down.
