Got my motorcycle license and have been learning to ride on my friends old suzuki 600. And im happy to say i only dropped it once

Anyway, the new kawasaki ninja 250R is due out this december, and it looks mean in green for only $3500! What do you guys think? should i buy this or are there any other bikes that are a great bang for the buck for a new rider. Price range being no more then $14K.
