For sake of comparison, the factory rear tire on my 2016 Bashan Brozz is a 110/90/17, giving it an outside diameter of 24.795 inches, and an outside circumference of 77.896 inches.
That means that a Hawk's rear tire revolves 780 times per mile, while my rear tire revolves 838 times in order to travel the same distance!

Good info, This is why we are slighty higher rpms with same sprocket set ups as the guys with the 18" back wheels. Thanks for posting specs!
