I'll put this out there just in case, but I have a Seth Laam Dual Seat off my 2014 C14 for sale. Just got it back a week ago Friday from being rebuilt, so I have approximately 400 miles on it. It's a great seat and very comfortable but I traded the bike today. It has the Carbon FX vinyl smooth sides and a silver topstitch.
So, if there are any members in the Cleveland Ohio area that may be thinking about a customized seat and can swap me with their seat drop me a PM. I only want a seat that matches in color the 2014, so no grey. Not sure what year they stopped using the grey color.
I have $410 invested and asking $325 + your stock seat. I can only do a quick local trade/buy since the bike is gone on Tuesday.
