MSRP $6,449

The KTM 125 SX has been given new airbox design and covers that make it easier to get to for replacement with virtually no tools required. The lightweight design of the frame makes it stronger with better handling and exact steering. The redesigned rear section of the swingarm allowed installation of a thicker rear wheel axle which besides the benefit of better tracking stability it also reduced the weight by 3.53 ounces.
