Motorcycle Jousting

Motorcycles are often treated as the modern day equivalent of horses. Some works take this an extra step and have the protagonist engage in jousting from the back of a motorbike.

Examples:

Comic Books

In keeping with their theme, the Knight and the Squire (England's equivalent of Batman and Robin) have lances they use from the back of their motorcycle steeds.

The movie Knightriders is all about this.

Terrence Hill and Bud Spencer do it in Watch Out, We're Mad
In a variant involving cars, in Herbie Rides Again there are people who are called Knights and who dress in wacky costumes who joust in one scene.
In another variant, Quick Change gives us a bizarre (and apparently lethal) bicycle jousting scene. Loomis panics and yells that "it's bad luck just seeing a thing like that!"
