RoadKillHeaven,
I have a 2015 and replaced the stock seat with Kawasaki's touring seat about a month ago. The stock and touring seats do look similar, but they are worlds apart when it comes to comfort. Based on my limited experience, (several short 200 km hops) I'd have to agree with most of what has been written about the touring seat thus far. It is 'cushier,' it seems to solve 'being shoved forward against the tank' to a certain extent, it is a bit taller and I find that I seem to be sitting a little more upright. I ride solo so I can't tell you about passenger comfort. So far, I am quite happy with it. I am 6'4", 205 lbs, with a 35 inch inseam.
