The Kawasaki KX100 is built for the young motocross racer transitioning from the popular KX85 minicycle to the full-sized, championship-winning KX125. Based on the smaller KX85 chassis, the rider is quickly familiar with the larger KX100, which benefits from an increase in engine displacement, larger wheels and tires, and suspension with longer travel.
The KX100 is powered by a liquid-cooled, two-stroke engine, with a machined finish on the bridges between the intake and exhaust ports to improve engine reliability and helps prevent seizure. With a displacement of 99cc, the motor breathes through a 28mm carburetor with a crescent slide to position the needle closer to the intake ports. A large air intake cutout on the airbox and large-diameter duct to the carburetor improve airflow. Meanwhile, a carbon-fiber intake reed valve aids throttle response and a smooth-shifting six-speed transmission gets the KX100 around the track without missing a beat.
The high-tensile steel perimeter frame for the KX100 supports a specially designed gas tank that lowers the fuel load, and in turn, the center of gravity, for improved handling. Protected by lime green plastic that wears graphics to match the larger-displacement models, the frame has a slim symmetric finish and provides a comfortable riding position.
