On a 1980 Puch Maxi 1.5 hp. Changed the front sprocket from 14 to 18 teeth. Changed the rear sprocket from 45 to 40 teeth. Actual speed increase was from 26.7 to 31. 8 mph. (I have a digital speedo.) Some loss in acceleration. Theoretical (no load) speed increase based on ratio of sprocket change is for a top speed of 38.5 mph. Need more power!!
