That's the name of a show that is on PBS. Its about an English Detective that some how ends on on a tropical island. Anyway, one of the island police force, in the first episodes, rode a bike that to me looked like a rated out enfield with an even worse side car.
Tonight, it was a very short scene, he goes to start his bike and it very clearly says Royal Enfield! Didn't get a chance to ID it other than appears military green. Just thought it was cool to have one show up as a regular on a TV show.
