Kawasaki Integrated Power-valve System varies exhaust port height for increased horsepower and produces a power-band with more low-end torque and mid-range, while retaining excellent top-end power. Intake and exhaust port bridges are machine-finished for reduced wear and improved reliability. KIPS system varies exhaust-port height for increased horsepower and torque at all rpm. Six-speed transmission has chrome-finished shift fork ends to resist wear and seizing while bushings on the second, third and fourth gears on the output shaft increase durability.
Chassis and Suspension – 2012 Kawasaki KX85 high-tensile steel perimeter frame with a specially designed fuel tank sitting inside the cage to keep the fuel load and the center of mass as low as possible for improved handling.
