The numbers just don't add up...
while on a 4 stroke scooter with 50cc you can get at least 40MPH.
The 2 stroke scoots (with variator) sometimes reach 60MPH.
Makes me question if the 66cc is really a 66cc, or a 33cc 2 stroke (2x stroke from a 4 stroke, thus compared to a 66cc 4 stroke)?
Again, being able to go 45 doesn't mean I'll go 45. It just means I'll be riding 28-32MPH more comfortably (on lower RPM's).
The thing is the 50cc runs smoother and higher RPM and is easy to get high speeds out of, the 66cc is a larger piston and runs a little rougher, but has a little more low end to it. I have a 32 tooth sprocket on mine and not broken in it scoots along great and at realitivly low RPM
