For Reference:
Larger rear sprocket = more low end, you will reach the top speed faster, the bike will accelerate harder, but you will lose top end speed.
Smaller rear sprocket = less low end but gains in mid range and top. The bike wll accelerate slower, but the top speed will increase.
Look to front sprocket adjustment for top speed, best combination is with a bigger front sprocket and smaller rear sprocket.
