Overall, the 250SX is an awesome machine, in the two-stroke world and the four-stroke world. Since this bike received the same major improvements in suspension, brakes and cosmetics as the other orange motocrossers, if you like the way those bikes feel, you will definitely love this bike. More and more four-strokes are being sold than two-strokes and the majority of us aren't even giving them a second thought. Maybe if more of these bikes are sold, more manufacturers will be able to keep them going. KTM seems pretty committed and it gives us riders just another option, and a good one at that.
