Duel Runner

Duel Runner, also called a D-Wheel (Ｄ・ホイール), is a special Duel Disk extension, developed by KaibaCorp introduced in Yu-Gi-Oh! 5D's for Turbo Duels. They are equipped with a screen which shows details like the current duel field or the Life Points. The helmet also serves to display various information, such as the ATK Points of a monster. It can approach speeds of up to 220 kilometers (136.62 miles) per hour during a Turbo Duel.

In each Duel Runner, there's one specific card integrated: the Field Spell Card "Speed World". If this card is activated, the duel screen on the Runner will appear. Other information, which are irrelevant to the Duel, can be switched off.

"Speed World" also activates the Duel Disk, which is attached to the Duel Runner.

Some Duel Runners are hybrids, with Card Zones that can be detached and used as standard Duel Disks.
