110cc = 4 stroke = power stroke once every 2 revolutions
50cc = 2 stroke = power stroke once every revolution

so no not 10 times more powerful and the 50cc two strokes are so torquey and powerful (the good ones nothing you will find on ebay).

do yourself a favour go to a track and watch the euros or w/c bikes going then compare. they are blisteringly quick.

maybe you should look at a 110-150cc motard? there big and lap about the same time as the elite watercooleds
