"Motorhead" is a song written by Ian "Lemmy" Kilmister while he was a member of the English space rock band Hawkwind. It was later recorded by Motörhead, as he called it this instead of Bastard on his then manager's advice.

Hawkwind are an English rock band known as one of the earliest space rock groups. Since their formation in November 1969, Hawkwind have gone through many incarnations and have incorporated many different styles into their music, including hard rock, progressive rock and psychedelic rock. They are regarded as an influential proto-punk band. Their lyrics often cover themes of urban life and science fiction.
