How much does a 05 KAWASAKI Ninja go for?

My brother wants me to sell his bike and its an 05 Kawasaki Ninja 600, i was just wonder whats the highest i can sell it for?|||Well, the kelly blue book trade-in value for a 2005 Kawasaki ZX600-N1 Ninja ZX-6RR (600 cc Ninja) with about 14000 miles, in good condition is $4415, but that is for a stock bike. Ask your brother if he has any aftermarket parts installed on his bike and if so you may want to increase the price. But if your mileage is a lot more than 14,000 mi, then you are probably going to have to lower the price. Realistically, if you are selling this bike as a private seller (as in you are selling it to another person, not a dealership), you are probably going to get somewhere around $4000 after bargaining.. I wouldn%26#039;t take anything less than that.|||Usually in my area they sell for about $2,500 to $3,000 but I would check with the local area boke dealer ships about selling prices to be safe.
