Argentina Biker Collision 4 Dirt-Bike Pile-Up in Race Caught on Video
A dirt bike race in Argentina caused quite the calamity ... a stuck bike resulted in multiple collisions during the competition -- though organizers say riders only sustained minor injuries.
Video shows how the crash at Enduro del Invierno in Mar del Plata, Argentina went down ... beginning after one moto rider got himself and his bike stuck in beach sand -- and he frantically waves to keep other racers from plowing into him.
A few bikers just barely miss the competitor ... before one runs right through rider and bike alike.
