Watch Bombuj. WHY isn't a question; it's a statement: WHY is a glimpse into the soul of motocross through the eyes of some of the most skilled participants in the world. It's a film juxtaposing the riders' intense talents on their bikes with their own unique personalities off. And while the stars of the movie differ from one another in their own special way, they all do what they do for the exact same reason: That unmistakable high that each and every one of us gets while riding.
