Yoshi's best car Mario Kart Wii?

This is an interesting question. I really think what you're trying to say is What are the cars in Mario Kart Wii. There are a lot of cars, but they are all grouped based on size. For example, the small characters have small karts and bikes, the medium characters have medium karts and bikes, and the large characters have large karts and bikes. I hope this answered your question, but just in case it didnt, the main kart in the game is the Standard Kart, and the main bike is the Standard Bike. Have a super day!
