A little late here, but I have a Russell Daylong Seat that is super comfy, but also super expensive. And you have to send them your stock seat to have it modified. But the end result is amazingly comfortable.
The seat is a Russell Daylong and yes, it is very comfy. The radiator covers are TCP covers and you can find them here:

Hello, just registered here. I've been over at FZ1OA for a few years and figured I'd come and play here too. Looking forward to learning and contributing. I've been a fizzy owner (2001) since last March and loving it.
