Mechanophilia (or mechaphilia[1]) is a paraphilia involving a sexual attraction to machines such as bicycles,[2] motor vehicles,[3][4] helicopters[5] and aeroplanes.[6]
This is treated as a crime in some nations, such as the United Kingdom,[2] with perpetrators being placed on a sex-offenders' register after prosecution.[7] Motorcycles are often portrayed as sexualized fetish objects to those who desire them
