Swift Jack

The Swift Jack is a kart that appears in Mario Kart Tour. It is a variant of the Wild Wing and is classified as a tour-exclusive High-End kart. Unlike the Wild Wing, slipstreaming lasts longer and yields more points when using this kart. The Swift Jack can be unlocked during the London Tour, where it is part of a Tour Gift for Gold Pass members after getting 310 Grand Stars. The tires appear to be the ones used on the Pipe Frame in Super Mario Kart, as well as in this game.
