Promotional poster: Moto madness

A group of promotors is looking for an image to put on a poster advertising a motorcycle show that will be traveling around the country. The show features street bikes, racing bikes, dirt bikes, custom bikes and antiques. The image must be of a motorcycle or a very obvious motorcycle component. The image may include a visible trademark, but the trademark must not be the subject (e.g., don't submit a BMW logo). The image must not have recognizable faces.
