150 SX 2018

With 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.
