Disclaimer: Down through the years China bike engine factories have always advertised their biggest engine as 80cc therefore we have listed them the same way on our website. However, the bore and stroke of an 80cc being 47x38mm only equals 66cc. Therefore there is no such thing as an 80cc bike motor and it truly does not exists and we want to make sure that you are aware of this. |
