The new 2017 KTM 250 SX comes with a high-tech lightweight chrome-moly steel frame which has a knack for easy handling, outstanding rideability, excellent stability and precise cornering. This bike has a high torsional rigidity and low longitudinal stiffness. In result of this, it gives a better absorption of the energy which is created from the front and rear suspension, sucking up bumps and jumps. In other words, it offers more comfort and less rider fatigue. The engine head is light in weight and is laterally attached contributes in precise cornering and reduction of vibration level. The KTM engineers were able to reduce the weight of the 2017 KTM 250 SX a kilogram lighter than that of the lightest competitor on the market.
