What speed could u return with up to on an 80cc quad bike and what speed could u find up to on a110cc -125cc quad bike?

and would u get duplicate speed on a motor bike and a dirt bike

Answers: these smaller quads are not made for speed or power. They are made for kids just starting to swot how to ride. Aftermarket companies dont even make hop up parts for them....
But you will be capable of get a highly developed speed if you were on a dirt bike.....
