The KTM 150 XC-W really is in a class of its own. Picking up where the iconic 200 XC-W left off, the 150 XC-W has the gap between 125 and 250 2-strokes firmly in its crosshairs. The ‘XC’ means cross-country, while the ‘W’ represents its wide-ratio transmission, giving it longer legs on faster sections while still maintaining low-down torque.
