It also has to do with the "one bike do all" mentality. These big adventure bikes sure check a lot of points: Ground clearance, long suspension travel, big and powerful engines, ergonomics etc. However, you still won't be touring like you do on a Goldwing or riding the twisties like your on a KTM Superduke 1290 or S1000R. Nor will you hit 300 kmph unless your on a typical 1000cc inline four. But KTM especially is trying to mix it all into one bike here, I think. As they did with the 1190 ADV.
I really don't get the race to produce the fastest, like Gas_Up mentions. 125 bhp 125 Nm torque... That's A LOT of power guys, seriously. If anything, I would ask for CT to be lighter, with better AND slightly longer suspension, and a few more extras as standard, like cruise control and heated grips. Maybe an engine mode for rain, 3-4 liters bigger fuel tank just to spoil us. The last, I mean THE last thing I would want to have on CT would be extra power. I would be happy riding bikes with a lot of grunt all across the rev range but produce "just" 125-130 bhp in the next 10 years as well. And if I would want more, I would go and buy a bike built for that purpose only.
Hell, if Honda were to actually produce a CT I described, I would be easily willing to pay as much as a premium package GS for it. Instant purchase, I mean it. I know I wouldn't be the only one. Far from it.
I am constantly considering the purchase of a GS, maybe ADV. The only thing that keeps me from pulling the trigger is the fact, I mean actual fact (no offense to anyone), that it won't be half as reliable as a Honda. The same goes for KTM. I don't care if its chain-drive. But with so many electronics, and so many talks with 1190 ADV owners, I know I will ruin it in less than two years at my riding rate. 80-90k kms in 2 years mean I will probably be left with the tyres and rims only.
