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 are one (later two) specific card(s) integrated: the Field Spell Card "Speed World" (and later "Speed World 2"). 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"/"Speed World 2" 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. Season 2 also introduces Duel Boards, customized skateboards build for children to do Turbo Duels; it also counts as a simplified version of a standard Duel Runner.

Anime

The first Duel Runner made by Yusei Fudo. Jack Atlas stole it from him along with "Stardust Dragon" before leaving his friends. According to Jack Atlas it has since been destroyed. In the English anime, Jack's current Duel Runner is the first one Yusei made. In Yu-Gi-Oh! 5D's Stardust Accelerator, this runner was not actually destroyed, but was actually being used to power an experiment in secret. The reason for this is unknown seeing as it was only seen in flashbacks.
Yusei Fudo's Duel Runner - Yusei Fudo uses a Duel Runner similar to his last one but colored in red, which is known to be a rare color.

It appears to have been created with such duels in mind, as it is able to take far more punishment than the typical Duel Runner. It is the Duel Runner equivalent to a Dark Signer's duel disk, with the dragon wing at the back and the teeth in the front. It was presumably destroyed upon Kalin's defeat.
After becoming a Dark Signer, Greiger's Duel Runner was redesigned for Shadow Turbo Duels, making it more powerful than before.
