21/49...not positive. Anyway I dropped my rear to a 46, took away some of the get up (countered with performance mods) and she lost that screaming buzz bomb feel/sound/effect when at highway speeds.
Simple sprocket info
bigger in front or smaller in rear will lose pick up but will add top end & lower rpm at highway speed.
smaller front or larger rear will increase pick up, cut into top end & increase rpms at speed.
1 tooth in the front is about the same as 2.5 or 3 teeth in the rear.
Hope this helps
