Kawasaki Original Custom Seat D1 Z1 Z2 F Tuck Roll I used to have this installed on a z750d1... but I don't think the seat lock worked when it was installed...? Regarding the mounting hook pin on the frame side, the previous seat was stolen and forcibly bent, so I'm not sure if I used a Z2 one. Please examine the underside for mounting details and make your judgment. While in storage, I had things placed on top of it, causing some unusual creases. I'm hoping they will eventually disappear. I removed the items and let it sit, and the dents have almost returned to their original shape, so I've replaced the photos. There are still some lines visible, but I think they will disappear eventually, or perhaps they will be unnoticeable once installed on a bike and sat upon. It could also be good for a custom base. Please examine the photos carefully and consider your purchase. Thank you.
