I'm guessing your bike didn't come with an owners manual ? All that info should be in it. The stock sprocket sizes are a 13 tooth front, a 48 tooth rear, and the standard chain type and length is #520 x 112 links. I recomend a 50 tooth sprocket on the rear tho. 125's just don't have the torque to turn a 48t well out of the hole.
