I was just reading about the 2015 Multistrada 1200S. That bike can certainly be considered in the ST segment.
Peoples' definitions of sports touring varies, but I wouldn't consider it in the same class. It is chain drive, it has only a small, MANUALLY adjustable windscreen that can only move 60mm (2.25"), handlebar mounted mirrors, less fairing, smaller electrical system, etc.
It has 160 hp and still under 500 lbs dry. More hp then the C14 and almost 200 lbs lighter. I know a big difference in price but the C14 is no longer the performance leader in the ST segment. A bump in HP wouldn't be the worst thing Kawi could do to this bike.
It is only 3 hp more (160 vs 157, with ram, at crank, depending on source) . And it is 150 pounds lighter, not 200 (520 vs 670 wet) and that still isn't right because the 670 on the Concours is WITH BAGS and it is without bags on the 1200S (I can't find the with bags on the 1200S).
A bump in HP wouldn't be the worst thing Kawi could do to this bike.
I don't think it would be a bad thing.
