I just sold my 25mm lowered seat and can't help - other than to say, try the other forum '2014-2017 Caponord 1200' - it is the main talkfest forum whereas this one started out as the 2013 forum and never really gained many active members (though, like you, I started here first).
The other forum is a bit messy nowdays so just go into the main 1200 Capo forum and list a post asking for a rider seat (state if you want a lowered one or an oem seat and also that you are in SA Aus - to filter out UK/USA guys as the freight will kill your budget).
