What is the difference between the 66cc and the 49cc

[JVROOM]

Because I'm fighting some vibration problems, I was wondering what is the difference between the 66cc and 49cc motors, and wondering how the Chinese are calling them80cc??? Also I have noticed on Rock Solid Bikes they are advertising Pistons and Barrels for for 50cc and 70cc motors. Can someone explain to me what this is all about? I'm wondering if the engine I selected is a bad actor and likes to shake and break? Thank you all for your help and consideration, John

Less vibration and more torque with the 66cc as you can use lower rpm's to travel at the same speed as the 50cc, making the riding experience a lot more pleasant.
