Hi Cro Magnon and welcome.

I would also recommend trying both bikes.
Perhaps you can reach out on some KTM forums and find a nearer owner who would let you try their Duke?

It is such a personal thing that you can't really take advice from somebody else on how the bike will make you feel...when I was looking I basically knew what I wanted (a petrol version of my burliest mtb!), but everybody I spoke to tried to steer me towards a Honda hornet or a bmw or... whatever it was that they enjoyed. As to the bike reviews in the press, not very objective is all I can say...

Personally I love my Tenere so far, I have only had it a couple of weeks and put about 400 miles on it due to cold wet weather, but I like its single torque and that fact it is not too much of a hooligan, it is a bit like a quality turbo diesel engine if that makes any sense! Also the riding position is very good for me, you can see over the top of all those annoying 4x4s and you feel like the king of the road..

You may find the Duke is just the thing for you though..
