Red Bull X-Fighters are freestyle motocross competitions contested in bullfighting arenas. Alongside the X Games, they are the most prestigious and most challenging freestyle motocross (FMX) competitions.

Red Bull X-Fighters are invitation tournaments where the best FMX riders in the world come face to face. The competitions' particular flair comes on the one hand from the relatively restricted space in the bullfighting arenas (and therefore the close proximity of the crowd to the sporting spectacle) and, on the other hand, from the replication of a number of rituals from a typical "corrida": for example, the riders are greeted by drum rolls and trumpet fanfares, and the public honours the riders' performances by waving white rags.
