Nice predicament to be fair! I sold my last bike in January this year and do miss them but promised my wife I'd stay safe and on four wheels for the forseeable.
I'd be looking at the 1198 Hypermotard as an option, as dare I say it the smaller cc version feels a bit weezy in comparison. A friend had the 1198s and I borrowed it for a weekend a while ago, very accomplished bike, great riding position, great looks etc.
The KTM 690 isnt a bad bike but motorways aren't friends with single cyld lumps. I had the older Duke 2 640cc a good while ago and it hated motorway journeys, also had a CCM R30 for a while and lastly a balls out Husaberg 501 full race motard (total animal - 60bhp 100kg short geared mono-cycle
) so speak from experience with a numb crotch. Aprillia Dorsoduro not too bad if you want the supermoto styling with a twin engine?
Other than that, the new-ish multistrada is supposed to be a fantastic all rounder with 150bhp on tap
Just my two pennies worth!! Enjoy whatever you choose.
