Why do people tell us what kind of handlebars their bike has and then ask what kind of sprockets to use?

How much faster do you want to go? If it's almost where you want it, start by going up a tooth in the front or down 2-3 in the rear. Don't get too crazy with the gearing or that 125 motor will have a hard time pulling you around.
