G5/C5 cruising speeds, different?

[exiledcarper]

Apologies if this has been covered before, but will the overall gear ratio be lower on the C5, with it's smaller wheels, or does it have a bigger c/shaft sprocket to compensate?
  Bottom line, will the two bikes cruise at the same rpm's in top gear, at a given speed?

I've read that the C5 has a one tooth larger front sprocket than the G5, I can't remember where I read it though.

This is true, but the C-5 has 18 inch wheels instead of 19 inch wiht the G-5. I am SURE that someone here will do the requisite math.
