Irvine, CA. (March 20, 2012) - The over-under bridge is one of the coolest obstacles in Supercross and for 2012, the GEICO MiniMotoSX will include just such an obstacle. The track map for the ninth annual MMSX taking place inside the Orleans Arena in Las Vegas on the Sunday following the Monster Energy Supercross finals also reveals a starting gate located outside the arena. This will leave more space on the arena floor for the rest of the track. And instead of watching the action, almost anybody can get out on the track to experience it firsthand.
