Bicycle Engine 50cc Vs 80cc. Let me make sure i have this clear the difference between the 80cc and the 50cc is that the 80cc has a little more torque and the 50cc is smoother less vibration because the pistion is smaller and that they both have about the same top speed 50cc is just slightly slower. The largest i know of so far is a 69 4 cc advertised as an 80 for a 2 stroke engine.
