Default Re: Sprocket ?'s (does size really matter?)

The motor rpm will drop for any given road speed with a smaller (less teeth) sprocket.

The top speed may or may not increase due to several factors...these engines only make so much HP, ad that's where you get the mph from.

Most bikes (if you are lucky) will hit a top speed somewhere in the mid 30's no matter what sprocket you use.
