We're talking about a specific class of bikes here- Sport Tourers. Not Goldwings and Geezer Glides or chromed out garage queens that don't see as many miles in a year as most people put on a ST in a month.
If I pay 19k for a ST class bike, I expect it to have better features and be a better bike overall than a lesser priced bike. But when you get down to it, you can pay less for a C14, add on the things that are missing from the 19k bike, and come out ahead with a better overall bike. The C14 out performs all of them aside from the K1600, and that is really in a class of it's own since it costs almost double what a C14 costs and is more in the Goldwing category when you look at the LT version.
All I'm saying is you can have upright riding position, wind protection, cruise control, comfortable seating, all the features a good touring bike has for less than the price of any of those you said were better. What are you missing, a gallon of fuel? That isn't even a factor for me because I like to get off the bike every 200 miles or so anyway.
I don't only look at the bike. My money is hard earned and I want the best value for the dollar. So in that case, yes, price does matter when you are looking at a hobby such as riding.
