I saw this ZZR recently. It was a standard ZZR and the owner took it to a "mechanic" to modernise it. So the mechanic junked the fairings including all the ram air system, cut away the rear frame and set about destroying the bike. As you can guess the bike never ran again and it is now up for sale. It really is sad to see this. Wrong on so many levels. I am trying to buy it and take it apart for spares. I will let you know if I do.
