The Kawasaki KX100 represents a natural step in the progression of any budding young motocross rider who is on the verge of outgrowing the KX85, but maybe still needs to grow a few inches, gain a few pounds or simply get a little more seat time before jumping aboard a full-sized KX250F. The new KX100 offers the perfect blend of a power and a larger chassis for an ideal learning curve en route to the big bikes.
