dear fellows i ve been riding cg125 since 2009. n if you really wanna talk about speed then let me tell you that 115 is not that issue for it. as per new 125 euro 2 is concerned ........... it's weight is less but it's electric system n it's pistons are totally different. luckily i ve experience of both :). new 125 can catch 120 even but only in the condition when you ride it the way it should be
