Thanks John. I actually just noticed that today. I found a cheap Triumph touring seat (stock seat off an '07 touring) no backrest can be added to this seat. So my basic decision is to try that seat (thinking if I get it reasonable enough I can probably get some/most of my money back out of it, if I find I need a backrest (this is seat wife liked sitting on it in the showroom) or just buck up the cash for a new Triumph touring with the backrest. Still thinking but not for much longer. Gonna pull the trigger on one of them here shortly.
Thanks,
Pug
