People ride motorbikes over rough and rocky ground in the Bemrose Trophy Trial.
Various shots of men (and possibly a few women?) on motorbikes following the rough and rocky course of the Bemrose Trophy Trial. One man falls off as he struggles up a rocky hill as a small crowd of people look on. A bull canters up one of the hilly pathways. Another rider manages to stay on their motorcycle as they go bouncing along the track - looks very uncomfortable.
