    A 250cc motorcycle has much larger wheels than that of a 250cc scooter, why is that?
    Comparing the same cc's of both vehicles, wouldn't the power be basically the same?
    Alfredo G is right about the hp, I'm not sure why I asked that power question. But the real question was why the small wheels? Pretty interesting answers too.

    because you need a lot more power to turn the big wheels than little wheels

    The reason being is that Piaggio the company that created the Vespa was a aircraft manufacturer during WWII. After the war they had a bunch of small aircraft wheels and decided to use them when they designed the first Vespa in 1947.

    The smaller the wheel diameter (less "trail" geometry), the more responsive it is. A higher "flick" factor is often preferred for urban commuting, as compared to open road touring. Kymco offers both small and large diameter wheel scooters.

    it does not matter, engines could be the same size put out diferent horsepower, and in this case, the scooter has smaller wheels because the engine puts out a smaller horse power.
