^ Replace heavy character with Funky Kong and you're correct. However, Funky Kong is just the best character in terms of speed. Other characters such as Toadette and the Magik Cruiser e xcel the most in offroad, while Toad and the Quaker are the best in acceleration, and so on. You'll find that almost everyone uses the Flame Runner, Mach Bike, and Bullet Bike.

But yeah, Funky Kong is the best overall.
