Hi mate, not sure on cc, its a 5HP if that helps.
It goes about 30mph but feels a lot faster when sat low down if you know what i mean. It will shift no problem at all with 2 adults. Its not road legal. Ive used it in the street as i live in a quiet cul de sac. Its fine if you have good neighbours.
The engine model number is 135212
My friends call me Bob
