I don't know what benefit aerodynamics have on a 110cc bike, seeing it barely passes 55MPH.
THe aerodynamic drag reduction you get from using the plastic frame, is compensated by the added weight for start-stopping the bike.
An aerodynamic frame like that makes sense if your cruising speed exceeds 45MPH. A 110cc cruises best between 35-40MPH, at about 3-4k RPM.
Taking it beyond 40MPH will hurt MPG.
I would think that a 110 can get 125MPG easily.
When maintaining 35-40MPH it might even reach 150MPG.
200MPG is a bit optimistic, unless the engine is ran in the 2,5k rpm range, if it could pull the load..
