riding my 42 defense model Bf Goodrich
If it was a straight bar it was not a DX! DX has 2 curved barsI had a straight bar Schwinn , a DX model I believe . All bare, like this one. no fenders or tank or accessories. I could wheelie that bike for miles if i had a long flat road. There's something to be said about a bare bones bike. The serial number will tell you a lot. Good luck , You will get a lot of good info here
