Daytona Supercross by the numbers

The high-flying competition of the AMA Amp'd Mobile Supercross Series returns to action under the lights of Daytona International Speedway for the Daytona Supercross by Honda on Friday.

But before the show can begin, a grassy section of the Speedway must be converted to a Supercross track by the track-building experts from Dirt Wurx USA.

Here's a look at the Daytona Supercross by the numbers, courtesy of Dirt Wurx:
