Was looking at a kawasaki homepage and it labelled the gpx 250r and the zx2r both ninjas. Is this true? What exactly is the difference? Is one imported? What about power and performance? Is the zx2r the same as the zxr 250? Yes i maybe a noob but i cant seem to get straight info about bikes anywhere. Ive tried a couple of sites ala www.totalmotorcycle.com. help me out.
