The FZ1 seat has been retrieved. It is wider more square at the back, fills the gap, and the contour at the tank isn't perfect, but OK. The kicker is, the pan is too much different, I'd have to do a lot of surgery to make it work. Mulling that over because I don't mind cutting up the pan..... got looking at the FZ6R pan again, and after riding it some more, it just needs to be flattened a bit and made wider (the pan), then new foam and cover (custom by me). I will spend a bit more time thinking about this before I get an XJ6 Diversion seat.... cheapest used seat now is $225 from France, and I would want a new cover which is $160 from Poland.
