So, to sum this bike up...
The KTM looks impressive on paper, works better than you think it will in the flesh and, aside from the mirrors that vibe the world behind into a visible mush over 6000rpm, it has every corner covered. It’s a shade under £16,000 OTR and that’s a lot of cash. But with the GT you’ve got a bike that can do pretty much what you want without any half measures.
I’d score this bike as a 9/10 as a tourer, superbike and nimble naked (because I don’t think that any bike deserves a 10/10 when it’s spread across such a wide range of skills) but don’t think that means this motorcycle is missing anything. It’s an old saying but if you’re a jack of all trades you can’t be a master of one. And that works fine in this context, as while the KTM 1290 Super Duke GT isn’t the best ever big roadster, superbike or specialist tourer, it is able to take the party to any motorcycle in those sectors when in the hands of the real riders in the real world.
It solves the puzzle of how you can take a bike and turn it into a motorcycle that can match what you need, your mood and the roads underneath you almost intuitively. It’s immense.
