Arthur Ketch's motorcycle

British Man of Letters Mr. Ketch owns a black Norton Commando motorcycle.

The motorcycle first appeared in The Foundry, while Dean was walking back to the Impala after purchasing food from a store. He gave a comment of appreciation, unaware on who it truly belonged to. Mr. Ketch is revealed to be following the Winchester brothers using this motorcycle, and in American Nightmare, he follows them to Mason City, Iowa.

After the brothers let the psychic Magda Peterson go, Mr. Ketch follows her into the bathroom and kills her, while bemoaning the Winchester brothers inability to "finish the job".

The motocycle's license plate is GK B02.
