Arenacross
"Arenacross is the crazy indoor off-spring of motocross racing first conceived in America in the 1970s. The sport takes the most spectacular elements of outdoor racing, boils them down into a concentrated cocktail and then shoehorns them into arenas onto purpose-built dirt tracks. Racing is short, sharp and shockingly spectacular with huge triple jumps, killer mogul sections and fast, banked corners all designed to provide a high-octane sensory feast."
