Sprinter

From Mario Kart Racing Wiki

This is the fastest kart for middleweights. It also has a decent Weight. But there are many flaws to it. The Acceleration is one of the worst in the game. Going Off-Road is not a good idea if you are using this kart. Its Handling is pretty bad. And it's Drift and Mini-Turbo stats are terrible. It is also called the B Dasher MK2.

     The Sprinter takes on an aerodynamic appearance and resembles the Jetsetter in various ways.
