2006 KTM 125 SX

KTM 125 SX

The 125 SX 2006 model is a light, robust and extremely agile bike that continues to challenge the power of the 4-stroke equivalent and provides the decisive argument in the 125 cc class. Easy in the curves and exceptionally controllable, this bike is in a class of its own. The 125 SX 2006 again allows for a range of more individual settings than any other Motocrosser in its class: seats, handlebar positions, adjustable fork offset (machined triple clamp) etc.
