New countries, new dirt, new requirements. Go behind the curtain with World Supercross as we haul in 6,000+ cubic metres of dirt across 450-500 truckloads to build a championship-grade track from bare concrete. Then watch Cooper Webb, Haiden Deegan, Eli Tomac and the WSX field walk the finished track for the first time, including the surprise return of the fan-favourite "Dragon's Back" obstacle.
