Easier said than done. I have a '11 and like the smoothness of the TC the way it is, don't want to lose that. I don't want a mickey mouse add on box, I want a reflash but there are only a couple that can do that and they are 1000's of miles away. I don't feel comfortable spending $400 on a reflash without time on a dyno.
And I think all your points and concerns are valid.
The Concours can easily "eat" the ancient Honda in just about every way and should be able eat the brand new Yamaha, in most ways too. But it is a shame that Kawasaki didn't make the secondary butterflies and linked brakes adjustable with a simple menu controls. As far as I know, this could be done, easily, and without a single hardware change at all.
The funny thing is that Kawasaki could make some minor hardware changes and end up right back at previous "miles above" the other two again: add cruise, add a gal to the tank, change headlights to projector HID, add profiles for the FI/Flies/brakes, change all bulbs to LED. Wham; not even a single change to the engine, trans, drive, physical brakes, controls, frame, FI, suspension, or main bodywork. Throw in adjustable bars or something just to spite the others. All quite possible in the next revision of the Concours. But it speaks volumes that the C-14, a 2008 release, is still extremely competitive even with a newly designed 2013 Yamaha....
