A go-kart is a type of open-wheel car and they are fun to ride!
Does a go cart have a motor that burns gas?
Some do but they in all shapes and forms, from motorless models to high-powered racing machines.
So go-karts are off road vehicles?
I believe you can not drive them on the streets. Superkarts, are able to beat racing cars or motorcycles on long circuits.
What is the average cost of a go-kart?
Very broad price range and I stand corrected. go-karts can be licensed for use on public roads, in some countries.
