2014 Kawasaki KX100, RACE READY! - A New Challenger Helps Riders Prepare for the Big Time! The Kawasaki KX100 represents a natural step in the progression of any budding young motocrosser who has outgrown the 85’s, but could still stand to grow a few more inches, gain a couple more pounds or simply put in a little more seat time before jumping aboard a powerful, full-sized KX250F. The new KX100 offers the perfect blend of a proportional power increase and a physically larger chassis for a more gradual learning curve en route to the big bikes.
