Has been a while since we had a speculative thread...
Now that the Concours has been dead in the USA/CA for a year and a half (and 6 years in the other markets), one wonders if Kawasaki will ever make a real sport touring bike again, a new Concours? The bike it is based on, the ZX-14 is still alive (surprisingly), so until that dies, it certainly unlikely.
Please don't point to the H2SX as a replacement, it is not a real sport tourer. Chain drive, small fixed windscreen, seating/bar position, short frame, narrow fairings, shorter range, etc, it is more of a relaxed sport bike with several touring features (heated grips, KIPASS, cruise, and OPTIONAL panniers), and at a vastly higher price. It is close in some ways, nice (for sure) but not quite what most people would think of as a Concours replacement. It could be made into one, though, if Kawasaki felt the desire. Add shaft drive, keep the electronics, but add an analog speedometer as well on a wider dash, widen the fairings a bit, add a real/adjustable/power windscreen, raise the bars, up the tank to 6+ gal, include the panniers, and they might have it.
Anyway, I suspect that tastes have changed permanently and we will not see the name "Concours" again (or "GTR" for our non-American friends).
