My daughter has an X2 1993 and it has a cam belt. All models from 1990 will have a cam belt but I'm not sure about the earlier X1 series prior to 1990. If you are replacing the belt, make sure you buy a cam belt kit with the new tensioner pulley assembly. I found this out the hard way when I pulled my daughters car apart to replace the belt. The pulley bearing was stuffed and also the tensioner spring gets weak over time.
