Tri-Speeder

The Tri-Speeder is an unlockable kart body that appears in Mario Kart 8. Hence the name, it is a three-wheeled kart that is painted green and slightly resembles a 1937 Morgan Super Sport. The Tri-Speeder is one of two vehicles in Mario Kart 8 to have only three wheels, with the other vehicle being the Bone Rattler. It sports an open V-twin engine with an ? Block from the front facing northeast housing the crankshaft, and two cylinders with heads shaped like mushrooms housing the pistons and valve gear. The cylinders and exhaust pipes shake while the kart is moving. The emblem is located on the hood. It has an advantage in weight and traction, but a disadvantage in acceleration and handling. It shares its stats with the Badwagon, the Steel Driver, the Standard ATV, and the GLA.

In Mario Kart 8 Deluxe, the Tri-Speeder has its stats changed, so it now boosts ground speed, water speed, weight and water handling, and all its other stats (except traction) are lowered. It now only shares its stats with the Steel Driver and the Bone Rattler. CPU Wario uses the Tri-Speeder with Off-Road tires and Morton uses it with the Monster tires. Skyward Sword Link also use this kart occasionally but pairs it up with the Triforce Tires instead. Additionally, Metal Mario pairs it with the Metal tires.

Trivia

 * This is the only non-DLC kart body in the game to not be raised above the Monster, Hot Monster, and Cushion tires. Instead, they are placed on the direct axles, similar to ATVs and bikes.
 * Its engine sound is actually a combination of three different sounds. The idling and revving sounds are unique for this vehicle, while the acceleration and boosting sounds are the same as Standard ATV and Jet Bike respectively.
