THE 2018 KTM 150 SX

The 150 SX has the agility of a 125 and enough muscle to take the fight to the 250cc 4-strokes, this bike punches well above its weight.

Its snarling engine sets benchmarks in terms of power and torque, rocketing its state-of-the-art chassis miles ahead of the competition. The top step of the podium does have the unmistakable scent of 2-stroke premix exhaust.

KTM engineers just love dropping weight year after year. The result: the 2018 KTM SX models are the slimmest, lightest dirt bikes out there. And all SX models feature an all new, tailor-made graphics kit and a Factory orange frame.

Because in this sport, champs deserve to look the part regardless of the dirt.
