Heavy vehicles can only be ridden by heavy characters. These characters are Wario, Waluigi, Donkey Kong, Bowser, King Boo, Rosalina, Funky Kong, and Dry Bowser.

Heavy Karts: Standard Kart L, Offroader, Flame Flyer, Piranha Prowler, Jetsetter, and Honeycoupe.

Heavy Bikes: Standard Bike L, Flame Runner, Wario Bike, Shooting Star, Spear, and Phantom.

The main good characteristics of these vehicles are their speed and weight. These karts and bikes have the best top speeds in the game, and you can push all of your light weight opponents out of the way, but with great top speed comes bad acceleration and off-road. These are heavy vehicles' weakest points. Try a heavy vehicle if you like what you've heard!
