From the wiki: “‘Motorhead’ was written by Lemmy, later of the group Motörhead, while he was a band member in Hawkwind; it was his last before leaving the band. The song first appeared on the B-side of Hawkwind’s 1975 single ‘Kings of Speed’. The title of the song is American slang for a ‘speed’ (amphetamine) freak. The song was written in the Hyatt Hotel (a.k.a. ‘Riot House’) in West Hollywood, California. Lemmy explains:
‘I was on tour with Hawkwind in 1974, we were staying at the Riot House and Roy Wood and Wizzard were also in town. I got this urge to write a song in the middle of the night. I ran downstairs to the Wizzard room, got Roy’s Ovation acoustic guitar, then hurried back to mine. I went on to the balcony and howled away for four hours. Cars were stopping and the drivers were listening then driving off, and there I was yelling away at the top of my voice.
‘The six thousand miles was a reference to Los Angeles, and the rest is self-explanatory. And yes, I am the only person to fit the word ‘parallelogram’ into a Rock’n’roll number! I’m very proud of that.’
