With its unstoppable character the Kawasaki KX 250 is ready to deal with any type of terrain with poise. The bike is propelled by a fuel injected, liquid cooled, 4 stroke, 249 cc engine which sends power to the rear wheel through a five speed gear box. The sound of the new 30mm shorter muffler is pretty impressive because it was designed with a 7mm wider outlet than the previous one. On the other hand, the stainless header now uses an acoustic resonator to decrease sound output and boost low-end power. The 2013 Kawasaki KX 250F is now offered with DFI map selector couplers to make the power change much faster than before.
