Is the Jet Silver/Stealth Really An 80cc Engine?
It is marketed as 80cc engines but in fact it is more like 68.6cc engines. There is no such thing as an 80cc 2-cycle bicycle engine. We refer to it as such because it is widely referred to as an 80cc. Benefits of the 68.6cc engines over the 49cc are more power for inclines and larger riders while getting about the same gas mileage.
