Edited to add: I have made a schoolboy error in posting before my first cup of coffee and only afterwards realising that despite it being more obvious than obvious, I am looking at a photo of a Gen 1. I leave my post up for anyone else who needs this info in the future, though.

You don't have the low profile seat. I do on my Gen 2, and the base for the rider is much, much thinner - but in my experience and despite what others have found, still very comfortable and suitable for all day, multiple day, touring. I weigh about 80Kg in my riding gear. See photo from the Czech Republic this summer, during which trip I found that long days in the saddle were all good. My 6 foot tall son found the pillion seat as identically comfortable to the M Sport seat that the bike came with.

I hope this answers your question.
