    Top Speed: 35-38 MPH (miles per hour) stock

    Fuel Economy: 100-150 miles per gallon

    *Note* CNS Carburetor upgrades will require extra matierial to fit flush around the manifold. This can be remedied by wrapping the manifold with electric tape or using PVC to fill in the gap between the carburetor port and the maifold.

    Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of "80cc", the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all "80cc" engine kits on the market today are actually 66cc in displacement size if measuring by US standards.

    Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of "80cc", the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. As such, there lies a discrepancy between measuring standards by the manufactures in China with those in the United States. As such, all "80cc" engine kits on the market today are actually 66cc in displacement size if measuring by US standards.
