Vikingo is an Argentine movie by director José Celestino Campusano. It has the peculiarity that the actors are not pros but actual real motorcyclist of the tough slums of the South of Buenos Aires. He had directed a documentary about them and then decided to do a work of fiction. It doesn't quite work too well, the acting is poor and there are some narrative problems. There are several Royal Enfields featured in the movie. You can watch it on youtube for free, but it is in Spanish only.
