This Kawasaki ninja 250r decal kit prices started at $53.95 (2011, July). As we know, truly Kawasaki has Ninja 250R special edition with special decal and great graphic, but if you want to install aftermarket accessories such as aftermarket decal kit, you should better check the aftermarket motorcycles part store. Enjoy your Ninja 250R bikes !
