I had a DXC 600 about the same era, it looked just about like yours. I believe the DXC was also commonly called the GS back then. It has a speedo and light so it's either a DXC or EXC, the MXC would not have lighting or speedo. DXC = desert EXC = enduro MXC = motocross (at least going from memory) I don't believe there was an EGS (dual sport) in that era, but I could be wrong. But every KTM 2 stroke I have ever had has been a blast to ride, except the 600 2T, which was too hard to kick over. Once running it was a beast. EXC 300 2T has been one of my favorites, the 350 2T should be lots of fun, good torque and good top end. My EXC 300 was super easy to start. Good luck, have fun!
