The Kawasaki KLX140 was introduced for the model year 2008. It is one of the only Japanese playbikes to sport a rear disc brake. In addition, many suspension, wheel, and brake parts will transfer over from the KX80/85/100. Performance is down, a bit, from the other Japanese 150 playbikes but the exhaust is whisper quiet. Changing out the exhaust and the carb can really wake this bike up.
