Why its a normal kawasaki. The kawasaki ninja series has always been loud in the top end. The ram air that we all love has increased this sound over the years. In fact many of the people that ride kaws do so because of the intake rush sound of the engine. The designers at kaw have even gone to the point of making sound deflectors to send this sound to the rider. Basically with the ram air the way it it- its a big resonate box right under you with a horn(air intake)putting the sound right up in front of the bike. If your bike seems loud after hearing rumours- point it out to the dealer- but don`t assume problems. The problems are the same in number as any other new bike. Don`t let a few problems- which seem to more prevelent among those with multiple nicknames and accounts on these forums- deter you from enjoying your bikes.
