i am from dallas-fortworth area TX, and one of the kawasaki dealer is ready to sell me a used 2010 kawasaki ninja 250r especial edition with less than 300 miles for 3500 with tax and title (out the door price). so far i think according to my research (craigslist, ebay, and other local dealers), this bike is cheaper. the bike is cosmetically excellent, but when the sales man tried to start it, it didnt stay stable without having to pull chokes. is it just because the bike was not used for long. or there may be some problems with the bike? i need help.
