I don't think you can make a minimoto road legal. 70 kit in a minimoto i don't think that will be possible, engine bracket size and engine is to big and I know its a 70cc engine but, Some mopeds do like 80-90 mph when de-restricted and exaust etc... Minimotos weigh nothing so if you can bodge it that will fly. It is like trying to put like a 2 litre turbo in a go kart not going to happen . lol
