2015 KTM 250 SX, Frame: The modern frame design of the SX models, comprising lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. A forged and milled cross-tube connects the two frame halves with the connecting rod of the linkage on the new SX frame for 2015. Omission of the weld seams leads to very precise manufacturing tolerances and greater safety - moreover, it saves another 60 grams of weight.
