When a motorbike gang kills an occultist, the evil spirit he was summoning inhabits a damaged bike. The bike is then bought and restored, but reveals its true nature when it tries to exact vengance on the gang, and anyone else who gets in its way.
I Bought a Vampire Motorcycle is a 1990 British comedy horror film about a motorcycle possessed by an evil spirit, which rides by itself and kills people, particularly members of a particular motorcycle gang. It stars Neil Morrissey as the bike's owner, Michael Elphick as a police inspector and Anthony Daniels as a priest who attempts to exorcise the bike's evil spirit.
